| Abstract: |
The search for objects of genuinely substellar mass as field stars or companions is frustraed by the difficulties in estimating both temperatures and masses. Recent determinations of the luminosity/mass functions for various field populations yield ambiguous or apparently contradictory results near the stellar mass limit. Searches for very low mass and substellar companions to nearby stars have been pursued using a variety of techniques. Current results suggest that companions with masses between 10 and 80 times the mass of Jupiter are rare. |
