Brown Dwarf Companions to Young Solar an
While this is a factor of 3 lower than the frequency of stellar companions to G-dwarfs in the same orbital range, it is significantly higher than the frequency of brown dwarfs in 0-3 AU orbits discovered through precision radial velocity ...

Introduction to Planetary Science: The Geological Perspective
24.2 Brown-Dwarf Stars The masses of the stellar companions that have been
detected by Doppler spectroscopy and by occultation range widely from less than
the mass of Jupiter Mj to more than 75 Mj. Consequently, many of these objects ...

Moreover a planet has no light of its own, and depends upon reflecting the light of
a nearby star, whereas a young brown dwarf may have an absolute magnitude of
around +17 and a surface temperature of the order of 2000 C. The luminosity ...

Planetary Systems in Binaries
The frequency of brown dwarf companions within 100 − 1000AU has not yet
been well constrained either (Gizis et al. 2001). Here we define a2,BD to be the
upper bound of the brown dwarf desert. The minimum upper bound a2,BD ≃ 3AU
is ...

Planet Formation: Theory, Observations, and Experiments
However, although more than 150 planets have now been discovered (mainly
orbiting Solar-type stars), very few brown-dwarf companions have been found.
This has led to the term “brown-dwarf desert” when describing the frequencies of
...

Atlas of Astronomical Discoveries
Fusion reactions of deuterium (heavy hydrogen) can occur in a brown dwarf, but
they generate almost no energy. Brown dwarfs are therefore extremely faint, and
predominantly emit infrared radiation. Almost no one doubts the existence of ...

be cool and of low luminosity during most of their lifetimes (e.g., Nelson et_ &L,
