The Physics of Brown dwarfs
We briefly outline the physics underlying the mechanical and thermal properties of brown dwarfs, which characterizes their interiors and their atmospheres. We mention the most recent improvements realyzed in the theory of brown dwarfs and the connection with experimental and observational tests of this theory.
متن کاملPossible Observational Criteria for Distinguishing Brown Dwarfs from Planets
The difference in formation process between binary stars and planetary systems is reflected in their composition as well as their orbital architecture, particularly orbital eccentricity as a function of orbital period. It is suggested here that this difference can be used as an observational criterion to distinguish between brown dwarfs and planets. Application of the orbital criterion suggests...
متن کاملThe Theory of Brown Dwarfs and Extrasolar Giant Planets
Straddling the traditional realms of the planets and the stars, objects below the edge of the main sequence have such unique properties, and are being discovered in such quantities, that one can rightly claim that a new field at the interface of planetary science and astronomy is being born. In this review, we explore the essential elements of the theory of brown dwarfs and giant planets, as we...
متن کاملA Planetary Companion to 70 Virginis1
An extremely low mass companion to the solar-type star 70 Virginis is inferred from the observed periodic Doppler reflex motion of the primary during 8 yr. The minimummass (M2 sin i) of 70 Vir “B” is 6.6 Jovian masses (MJ), which falls in the mass range associated with “extrasolar giant planets” (0.3–15 MJ ). An orbital fit to the velocities yields a period P 5 116.6 days, an amplitude K 5 318 ...
متن کاملA Distant Stellar Companion in the Υ Andromedae System
Upsilon Andromedae is an F8V star known to have an extrasolar system of at least 3 planets in orbit around it. Here we report the discovery of a low-mass stellar companion to this system. The companion shares common proper motion, lies at a projected separation of ∼750 AU, and has a spectral type of M4.5V. The effect of this star on the radial velocity of the brighter primary is negligible, but...
