Enrique García-Berro
Enrique García-Berro Montilla (1959 - 2017) was a Spanish and Catalan astrophysicist. He was a world-recognized expert in stellar astrophysics, in particular in the theory of white dwarf stars and type Ia supernovae. Life and career García-Berro earned his master's degree in physics from the University of Barcelona in 1982 with highest honors. He went on at Barcelona to pursue his Ph.D. with Jordi Isern. He earned his Ph.D. in theoretical astrophysics in 1987 ''cum laude.'' In 1987, García-Berro was appointed Associate Professor in Applied Physics at the Polytechnic University of Catalonia (UPC). In 2003, he was promoted to full Professor. From 2006 to 2013, he was the Vice-Rector at the UPC. García-Berro proved to be a capable administrator, and was appointed to be the director of the Serra Húnter program, designed to attract world-class faculty to Catalonian universities. García-Berro also served as the assistant director of the Institut d'Estudis Espacials de Catalun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Dwarf
A white dwarf is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to the Sun's, while its volume is comparable to the Earth's. A white dwarf's faint luminosity comes from the emission of residual thermal energy; no fusion takes place in a white dwarf. The nearest known white dwarf is at 8.6 light years, the smaller component of the Sirius binary star. There are currently thought to be eight white dwarfs among the hundred star systems nearest the Sun. The unusual faintness of white dwarfs was first recognized in 1910. The name ''white dwarf'' was coined by Willem Luyten in 1922. White dwarfs are thought to be the final evolutionary state of stars whose mass is not high enough to become a neutron star or black hole. This includes over 97% of the other stars in the Milky Way. After the hydrogen- fusing period of a main-sequence star of low or medium mass ends, such a star will expand to a red giant ...

Sallent de Gállego (in Aragonese: ''Sallent de Galligo'' or ''Sallén de Galligo'') is a municipality located in the province of Huesca, Aragon, Spain. The town is located in the central Pyrenees besides the reservoir of Lanuza on the foot of some of the highest summits of the chain, close to the border with France. It is part of the Alto Gállego comarca, and it is the capital of the Tena Valley. These localities are also part of the municipality: Formigal, Portalet d'Aneu, Lanuza, Escarrilla, Tramacastilla and Sandiniés. Landscape The Gállego river runs through the town and its first tributary, the ''Aguas Limpias'', unites to the Gállego inside the town. Both rivers' sources are inside the municipality. The Foratata peak (2,000 m) towers over the town, being an iconic peak for all the valley. Other important summits belonging to the municipality are Anayet, Tres Hombres, Arriel and Balaitous, many of them are over 3000 meters high. The GR 11 route that goes alon ...

Pyrenees
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean Sea, Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene (mythology), Pyrene is a princess who eponym, gave her name to the Pyrenees. The Greek historiography, Greek historian Herodotus says Pyrene is the name of a town in Celts, Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Narbonensis, Mediterranean Gaul by whom the hero Hercules was given hospitality during his ...

Gaia (spacecraft)
''Gaia'' is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision. The mission aims to construct by far the largest and most precise 3D space catalog ever made, totalling approximately 1 billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among others. To study the precise position and motion of its target objects, the spacecraft monitored each of them about 70 times over the five years of the nominal mission (2014–2019), and continues to do so during its extension. The spacecraft has enough micro-propulsion fuel to operate until about November 2024. As its detectors are not degrading as fast as initially expected, the mission could therefore be extended. ''Gaia'' targets objects brighter than magnitude 20 in a broad photometric band that covers the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravitational Wave
Gravitational waves are waves of the intensity of gravity generated by the accelerated masses of an orbital binary system that propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as waves similar to electromagnetic waves but the gravitational equivalent. Gravitational waves were later predicted in 1916 by Albert Einstein on the basis of his general theory of relativity as ripples in spacetime. Later he refused to accept gravitational waves. Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, since that law is predicated on the assumption that physical interactions propagate instantaneously (at infinite speed)showing one of the ways the methods of Newtonian physics are unable to explain ph ...
