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.
