Astronomy and Astrophysics the Closest Extrasolar Planet a Giant Planet around the M4 Dwarf Gl 876
Precise radial velocity observations of the nearby M4 dwarf Gl 876 with the Observatoire de Haute Provence 1.93 m telescope and the new 1.20 m swiss telescope at la Silla indicate the presence of a jovian mass companion to this star. The orbital fit to the data gives a period of 60.8 days, a velocity amplitude of 246m.s −1 and an eccentricity of 0.34. Assuming that Gl 876 has a mass of 0.3 M ⊙ ...

متن کاملMission to planet Earth.
Anthraquinones are the largest group of the naturally occurring quinones. Both natural and synthetic anthraquinones are widely used in medical preparations, colourants in foods, hair dyes and others. Chrysazin (1, 8-dihydroxy-9, 10-anthracenedione; Figure 1) is a synthetic anthraquinone with 1, 8-dihydroxy groups like other natural anthraquinones such as emodin and chrysophanol which have been ...
متن کاملThe mass of dwarf planet Eris.
The discovery of dwarf planet Eris was followed shortly by the discovery of its satellite, Dysnomia, but the satellite orbit, and thus the system mass, was not known. New observations with the Keck Observatory and the Hubble Space Telescopes show that Dysnomia has a circular orbit with a radius of 37,350 +/- 140 (1-sigma) kilometers and a 15.774 +/- 0.002 day orbital period around Eris. These o...
