Abstract:
Sun-like stars have stellar, brown dwarf, and planetary companions.
To help constrain their formation and migration scenarios, we analyze
the close companions (orbital period<5yr) of nearby Sun-like stars.
By using the same sample to extract the relative numbers of stellar,
brown dwarf, and planetary companions, we verify the existence of a
very dry brown dwarf desert and describe it quantitatively.
