HD 75898
HD 75898 is an 8th magnitude star approximately 255 light years away in the constellation Lynx. The star is 28% more massive, 60% larger, and 3 times as luminous than our local star. It is a metal-rich star, with 186% the solar abundance of iron. In 2007 the California and Carnegie Planet Search team found one planet orbiting HD 75898. In 2019 the HD 75898 system was chosen as part of the NameExoWorlds campaign organised by the International Astronomical Union, which assigned each country a star and planet to be named. HD 75898 was assigned to Croatia. The winning proposal named the star Stribor, after the god of winds in Slavic mythology, and the planet Veles, after a deity of earth, water and the underworld in Slavic mythology. Planetary system The planet HD 75898 b was discovered by the radial velocity method in 2007. At the time the centre of mass of the system appeared to be accelerating, indicating the presence of a third, more distant, component at least th ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hipparcos Objects
''Hipparcos'' was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993. It was the first space experiment devoted to precision astrometry, the accurate measurement of the positions of celestial objects on the sky. This permitted the first high-precision measurements of the intrinsic brightnesses (compared to the less precise apparent brightness), proper motions, and parallaxes of stars, enabling better calculations of their distance and tangential velocity. When combined with radial velocity measurements from spectroscopy, astrophysicists were able to finally measure all six quantities needed to determine the motion of stars. The resulting ''Hipparcos Catalogue'', a high-precision catalogue of more than 118,200 stars, was published in 1997. The lower-precision ''Tycho Catalogue'' of more than a million stars was published at the same time, while the enhanced Tycho-2 Catalogue of 2.5 million stars was published in 2000. ''Hipparcos'' ...

There are an additional 2,054 potential exoplanets from Kepler's first mission yet to be confirmed, as well as 978 from its " Second Light" mission and 4,081 from the Transiting Exoplanet Survey Satellite (TESS) mission.

HD 5319
HD 5319 is an 8th magnitude star approximately 319 light years away in the constellation Cetus. It is a subgiant star of spectral type K3, having run out of hydrogen in its core. When it was main-sequence, the spectral type was early F or late A. The absolute magnitude (apparent magnitude at 10 parsecs) is 3.05, which would translate to easy naked eye visibility, but its distance is ten times greater, so its apparent magnitude is 8.05 (100 times fainter than its absolute magnitude), it is not visible to the naked eye and binoculars are needed. Planetary system On January 11, 2007, the California and Carnegie Planet Search team found an extrasolar planet with a minimum mass 1.76 times that of Jupiter orbiting the star. It was published in the December 1, 2007 edition of the Astrophysical Journal. A second planet was discovered in November 2014. Orbital simulations of the dynamical stability of the planetary system indicate that it is likely in a 4:3 mean motion resonance. Pr ...

Doppler Spectroscopy
Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star. 1,018 extrasolar planets (about 19.5% of the total) have been discovered using Doppler spectroscopy, as of November 2022. History Otto Struve proposed in 1952 the use of powerful spectrographs to detect distant planets. He described how a very large planet, as large as Jupiter, for example, would cause its parent star to wobble slightly as the two objects orbit around their center of mass. He predicted that the small Doppler shifts to the light emitted by the star, caused by its continuously varying radial velocity, would be detectable by the most sensitive spectrographs as tiny redshifts and blueshifts in the star's emission. However, the technology of the time produced radial-velocity meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veles (god)
Veles,; Serbo-Croatian, Czech, Slovak, Russian, Slovenian: ''Veles''; Ruthenian and Old Church Slavonic: Велесъ; be, Вялес, translit=Vialies also known as Volos, is a major god of earth, waters, livestock, and the underworld in Slavic paganism. His mythology and powers are similar, though not identical, to deities such as Loki and Hermes. According to reconstruction by some researchers, he is the opponent of the supreme thunder god Perun. As such he probably has been imagined as a dragon, which in the belief of the pagan Slavs is a chimeric being, a serpent that devours livestock. His tree is the willow much like Perun's tree is the oak. No direct accounts survive, but reconstructionists speculate that he may directly continue aspects of the Proto-Indo-European pantheon. Sources Veles is one of few Slavic gods for which evidence of offerings can be found in all Slavic nations. The ''Primary Chronicle'', a historical record of the early Kievan Rus, is the earl ...

Stribog
Stribog is a god in Slavic mythology found in three East Slavic sources, whose cult may also have existed in Poland. The sources do not inform about the functions of the god, but nowadays he is most often interpreted as a wind deity who distributes wealth.' Sources Stribog appears for the first time in the 12th-century ''Primary Chronicle'' together with other gods for whom Vladimir the Great erected statues: In ''The Tale of Igor's Campaign'', the winds are called ''Stribog's grandsons'': The ''word of John Chrysostom'' also mentions Stribog: Legacy After Christianization, the name was preserved in toponymy: Стрибожь, ''Stribozh in Novgorod Governorate, Стрибоже, ''Strybozhe'' leak, Стрибожская, ''Strybozhskaya'' river in Kiev Voivodeship, Стрибож, ''Strybozh'' village in Zhytomyr Oblast, in Poland '' Strzyboga'' village and the ''Striboc'' (= ''Stribog'') stream near Tczew, attested in the 1282, and possibly Latin name for river fr ...

NameExoWorlds
NameExoWorlds (also known as IAU NameExoWorlds) is the name of various projects managed by the International Astronomical Union (I.A.U.) to encourage names to be submitted for astronomical objects, which would later be considered for official adoption by the organization. History The first such project (NameExoWorlds I), in 2015, regarded the naming of stars and exoplanets. 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these. Many of the names chosen were based on world history, mythology and literature. In June 2019, another such project (NameExoWorlds II), in celebration of the organization's hundredth anniversary, in a project officially called IAU100 NameExoWorlds, welcomed countries of the world to submit names for exoplanets and their host stars. A star with an exoplanet was assigned to each country, and members of the public submitted names for them. In August 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
