Brown Dwarf Companions To Young Solar Analogs

We present results from an adaptive optics survey conducted with the
Palomar and Keck telescopes over 3 years, which measured the frequency of stellar and sub-stellar companions to Sun-like stars. The survey sample contains 266 stars in the 3-10000 million year age range at heliocentric distances between 8 and 200 parsecs and with spectral types between F5-K5. A sub-sample of 101 stars, between
3-500 million years old, were observed in deep exposures with a coronagraph to search for faint …
