Rochus Gliese
Rochus Gliese (6 January 1891 — 22 December 1978) was a German actor, director, production designer, and Academy Award-nominated art director of early films from the 1910s and 1920s. He was born in Berlin. He is most remembered in the United States for his work as an art director on the film '' Sunrise: A Song of Two Humans''. Most of his other films did not receive wide release in the United States.

Wilhelm Gliese
Wilhelm Gliese (, English ; 21 June 1915 – 12 June 1993) was a German astronomer who specialized in the study and cataloging of nearby stars. Life Gliese was born in Goldberg, now in Polish Silesia, the son of judge Wilhelm Gliese. He worked at the Astronomisches Rechen-Institut, first in Berlin and then in Heidelberg. While a student he was encouraged by the Dutch astronomer Peter van de Kamp to study nearby stars, which he did for the rest of his life. His astronomical research was interrupted during World War II when he was conscripted into the German ''Wehrmacht'' in 1942 and sent to the Eastern Front. In 1945, he was taken prisoner by the Soviets and was not released until 1949. He finally resumed his research at the Institute, which had been moved by the U.S. Army to Heidelberg after the war. Although he nominally retired in 1980, he continued his research at the Institute until his death in 1993. Catalogs of nearby stars He is best known for his '' Catalogue of N ...

Gliese Catalogue Of Nearby Stars
The ''Gliese Catalogue of Nearby Stars'' (, English ) is a star catalogue listing stars located within 25 parsecs (81.54 lightyear, ly) of the Sun. First edition and supplements In 1957 Germans, German astronomer Wilhelm Gliese published his first star catalogue of 915 known stars within of Earth, listing their known properties and ordered geographically by right ascension. Stars in the first catalogue are designated by coding ''GL NNN'', the N representing the consecutive integer number based on this order. Gliese published an update as the ''Catalogue of Nearby Stars'' in 1969, all known stars to , which catalogued 1,529 stars, encoded as ''Gl NNN.NA'' (prefix Gl and the entries of twelve years before gained a .0 affix; the more than 500 additional stars were recorded using interspersed 0.1, 0.2 etc. numbering). This list therefore numbered from 1.0 to 915.0 as no stars were entered after 915.0. and retained a strict right ascension order. A Supplement published in 1970 by Ri ...

Gliese 163
Gliese 163 is a faint red dwarf star with multiple exoplanetary companions in the southern constellation of Dorado. Other stellar catalog names for it include HIP 19394 and LHS 188. It is too faint to be visible to the naked eye, having an apparent visual magnitude of 11.79 and an absolute magnitude of 10.91. This system is located at a distance of 49.4 light-years from the Sun based on parallax measurements. Judging by its space velocity components, it is most likely a thick disk star. This is a small M-type main-sequence star with a stellar classification of M3.5V. It has a relatively low activity level for a red dwarf of its mass, suggesting it is an old star with an age of at least two billion years. This star has 41% of the mass and radius of the Sun. It is spinning slowly with a projected rotational velocity of 0.85 km/s and has a rotation period of 61 days. The star is radiating just 2% of the luminosity of the Sun from its photosphere at an effectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliese 229
Gliese 229 (also written as Gl 229 or GJ 229) is a binary system composed of a red dwarf and the first brown dwarf seen by astronomers, 18.8 light years away in the constellation Lepus. The primary component has 58% of the mass of the Sun, 69% of the Sun's radius, and a very low projected rotation velocity of 1 km/s at the stellar equator. The star is known to be a low activity flare star, which means it undergoes random increases in luminosity because of magnetic activity at the surface. The spectrum shows emission lines of calcium in the H and K bands. The emission of X-rays has been detected from the corona of this star. These may be caused by magnetic loops interacting with the gas of the star's outer atmosphere. No large-scale star spot activity has been detected. The space velocity components of this star are U = +12, V = –11 and W = –12 km/s. The orbit of this star through the Milky Way galaxy has an eccentricity of 0.07 and an orbital inclinat ...

Gliese 581
Gliese 581 () is a red dwarf star of spectral type M3V at the center of the Gliese 581 planetary system, about 20 light years away from Earth in the Libra constellation. Its estimated mass is about a third of that of the Sun, and it is the 89th closest known star to the Sun. Gliese 581 is one of the oldest, least active M dwarfs known. Its low stellar activity improves the likelihood of its planets retaining significant atmospheres, and lessens the sterilizing impact of stellar flares. History of observations Gliese 581 is known at least from 1886, when it was included in Eduard Schönfeld's ''Southern (SD)''—the fourth part of the '. The corresponding designation is BD -7 4003. Characteristics The name ''Gliese 581'' refers to the catalog number from the 1957 survey ''Gliese Catalogue of Nearby Stars'' of 965 stars located within 20 parsecs of the Earth. Other names of this star include ''BD-07° 4003'' ( BD catalogue, first known publication) and ''HO Librae'' (var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliese 581d
Gliese 581d (often shortened to Gl 581d or GJ 581d) is a proposed extrasolar planet orbiting within the Gliese 581 system, approximately 20.4 light-years away in the Libra constellation. It is the third planet claimed in the system and (assuming a five-planet model) the fifth in order from the star. Though not confirmed to be a terrestrial planet and significantly more massive than Earth (at 6.98 Earth masses), the Super-Earth is the first exoplanet of terrestrial mass regarded as orbiting within the habitable zone of its parent star. Assuming its existence, computer climate simulations have confirmed the possibility of the existence of surface water and these factors combine to a relatively high measure of planetary habitability. Discovery A team of astronomers led by Stéphane Udry of the Geneva Observatory used the HARPS instrument on the European Southern Observatory 3.6 meter telescope in La Silla, Chile, to discover the planet in 2007. Udry's team employed the radia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliese 667
Gliese 667 (142 G. Scorpii) is a triple-star system in the constellation Scorpius lying at a distance of about from Earth. All three of the stars have masses smaller than the Sun. There is a 12th-magnitude star close to the other three, but it is not gravitationally bound to the system. To the naked eye, the system appears to be a single faint star of magnitude 5.89. The system has a relatively high proper motion, exceeding 1 second of arc per year. The two brightest stars in this system, GJ 667 A and GJ 667 B, are orbiting each other at an average angular separation of 1.81 arcseconds with a high orbital eccentricity, eccentricity of 0.58. At the estimated distance of this system, this is equivalent to a physical separation of about 12.6 Astronomical unit, AU, or nearly 13 times the separation of the Earth from the Sun. Their eccentric orbit brings the pair as close as about 5 AU to each other, or as distant as 20 AU, corresponding to an eccentricity of 0.6.B ...

Gliese 682
Gliese 682 or GJ 682 is a red dwarf. It is listed as the 49th-nearest known star to the Sun, being about 16 light years away from the Earth. Even though it is close by, it is dim with a magnitude of 10.95 and thus requires a telescope to be seen. It is located in the constellation of Scorpius, near the bright star Theta Scorpii. The star is in a crowded region of sky near the Galactic Center, and so appears to be near a number of deep-sky objects from the Solar System's perspective. The star is only 0.5 degrees from the much more distant globular cluster NGC 6388. Hypothetical planetary system Two candidate planets were detected orbiting Gliese 682 in 2014, one of which would be in the habitable zone. However, a 2020 study did not find these planets and concluded that the radial velocity signals were probably caused by stellar activity. See also *List of nearest stars This list covers all known stars, brown dwarfs, and sub-brown dwarfs within of the Sun. So ...

Gliese 710
Gliese 710, or HIP 89825, is an orange star in the constellation Serpens Cauda. It is projected to pass near the Sun in about 1.29 million years at a predicted minimum distance of 0.051 parsecs— (about 1.60 trillion km) – about 1/25th of the current distance to Proxima Centauri. Such a distance would make for a similar brightness to the brightest planets, optimally reaching an apparent visual magnitude of about −2.7. The star's proper motion will peak around one arcminute per year, a rate of apparent motion that would be noticeable over a human lifespan. This is a timeframe, based on data from ''Gaia'' DR3, well within the parameters of current models which cover the next 15 million years. Description Gliese 710 currently is from Earth in the constellation Serpens and has a below naked-eye visual magnitude of 9.69. A stellar classification of K7 Vk means it is a small main-sequence star mostly generating energy through the thermonuclear fusion of hydrogen at ...
