BPM 37093
BPM 37093 (V886 Centauri) is a variable white dwarf star of the DAV, or ZZ Ceti, type, with a hydrogen atmosphere and an unusually high mass of approximately 1.1 times the Sun's. It is about from Earth in the constellation Centaurus and vibrates; these pulsations cause its luminosity to vary. Like other white dwarfs, BPM 37093 is thought to be composed primarily of carbon and oxygen, which are created by thermonuclear fusion of helium nuclei in the triple-alpha process.Late stages of evolution for low-mass stars , Michael Richmond, lecture notes, Physics 230, , accessed online May 3, 2007.

Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Only Lovers Left Alive
''Only Lovers Left Alive'' is a 2013 fantasy comedy-drama film written and directed by Jim Jarmusch, starring Tilda Swinton, Tom Hiddleston, Mia Wasikowska, Anton Yelchin, Jeffrey Wright, Slimane Dazi and John Hurt. An international co-production of the United Kingdom and Germany, the film focuses on the romance between two vampires, and was nominated for the Palme d'Or at the 2013 Cannes Film Festival.

Jim Jarmusch
James Robert Jarmusch (; born January 22, 1953) is an American film director and screenwriter. He has been a major proponent of independent cinema since the 1980s, directing films including '' Stranger Than Paradise'' (1984), '' Down by Law'' (1986), ''Mystery Train'' (1989), ''Dead Man'' (1995), '' Ghost Dog: The Way of the Samurai'' (1999), ''Coffee and Cigarettes'' (2003), '' Broken Flowers'' (2005), ''Only Lovers Left Alive'' (2013), '' Paterson'' (2016), and '' The Dead Don't Die'' (2019). ''Stranger Than Paradise'' was added to the National Film Registry in December 2002. As a musician Jarmusch has composed music for his films and released three albums with Jozef van Wissem.

Lucy In The Sky With Diamonds
"Lucy in the Sky with Diamonds" is a song by the English rock band the Beatles from their 1967 album '' Sgt. Pepper's Lonely Hearts Club Band''. It was written primarily by John Lennon and credited to the Lennon–McCartney songwriting partnership. Lennon's son Julian inspired the song with a nursery school drawing that he called "Lucy – in the sky with diamonds". Shortly before the album's release, speculation arose that the first letter of each of the nouns in the title intentionally spelled "LSD", the initialism commonly used for the hallucinogenic drug lysergic acid diethylamide. Lennon repeatedly denied that he had intended it as a drug song, and attributed the song's fantastical imagery to his reading of Lewis Carroll's '' Alice in Wonderland'' books. The Beatles recorded "Lucy in the Sky with Diamonds" in March 1967. Adding to the song's ethereal qualities, the musical arrangement includes a Lowrey organ part heavily treated with studio effects, and a drone provided by ...

The Beatles
The Beatles were an English Rock music, rock band, formed in Liverpool in 1960, that comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the Cultural impact of the Beatles, most influential band of all time and were integral to the development of counterculture of the 1960s, 1960s counterculture and popular music's recognition as an art form. Rooted in skiffle, beat music, beat and 1950s rock and roll, rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways; the band also explored music styles ranging from folk music, folk and Music of India, Indian music to Psychedelic music, psychedelia and hard rock. As Recording practices of the Beatles, pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's Baby boomers, youth and sociocultural movements.

Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard conditions for temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) color diamond blue (bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fermi Sea
A composite fermion is the topological bound state of an electron and an even number of quantized vortices, sometimes visually pictured as the bound state of an electron and, attached, an even number of magnetic flux quanta. Composite fermions were originally envisioned in the context of the fractional quantum Hall effect, but subsequently took on a life of their own, exhibiting many other consequences and phenomena. Vortices are an example of topological defect, and also occur in other situations. Quantized vortices are found in type II superconductors, called Abrikosov vortices. Classical vortices are relevant to the Berezenskii–Kosterlitz–Thouless transition in two-dimensional XY model. Description When electrons are confined to two dimensions, cooled to very low temperatures, and subjected to a strong magnetic field, their kinetic energy is quenched due to Landau level quantization. Their behavior under such conditions is governed by the Coulomb repulsion alone, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Body-centered Cubic
In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals. There are three main varieties of these crystals: *Primitive cubic (abbreviated ''cP'' and alternatively called simple cubic) *Body-centered cubic (abbreviated ''cI'' or bcc) *Face-centered cubic (abbreviated ''cF'' or fcc, and alternatively called ''cubic close-packed'' or ccp) Each is subdivided into other variants listed below. Although the ''unit cells'' in these crystals are conventionally taken to be cubes, the primitive unit cells often are not. Bravais lattices The three Bravais lattices in the cubic crystal system are: The primitive cubic lattice (cP) consists of one lattice point on each corner of the cube; this means each simple cubic unit cell has in total one lattice point. Each atom at a lattice point is then shared equally between eight adjacent cubes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteroseismology
Asteroseismology or astroseismology is the study of oscillations in stars. Stars have many resonant modes and frequencies, and the path of sound waves passing through a star depends on the speed of sound, which in turn depends on local temperature and chemical composition. Because the resulting oscillation modes are sensitive to different parts of the star, they inform astronomers about the internal structure of the star, which is otherwise not directly possible from overall properties like brightness and surface temperature. Asteroseismology is closely related to helioseismology, the study of stellar pulsation specifically in the Sun. Though both are based on the same underlying physics, more and qualitatively different information is available for the Sun because its surface can be resolved. Theoretical background By linearly perturbing the equations defining the mechanical equilibrium of a star (i.e. mass conservation and hydrostatic equilibrium) and assuming that the pe ...

Whole Earth Blazar Telescope
The Whole Earth Blazar Telescope (WEBT) is an international consortium of astronomers created in 1997, with the aim to study a particular category of Active Galactic Nuclei (AGN) called blazars, which are characterized by strong and fast brightness variability, on time scales down to hours or less. This collaboration involves many telescopes observing at optical, near-infrared, and radio (millimetric and centimetric) wavelengths. Thanks to their different geographic location all around the world, the emission variations of the pointed source can be monitored 24 hours a day, with the observing task moving from east to west as the Earth rotates. WEBT observations are often carried out in conjunction with observations at higher frequencies, from ultraviolet to gamma rays, performed by both space and ground-based telescopes. In this way, information on blazar emission over almost the whole electromagnetic spectrum can be obtained. The multi-wavelength studies performed by the WEBT hav ...
