[60.02] The Luminosity Function of Ultracool Dwarfs

K. Cruz (U. Pennsylvania)

We have created a statistically complete sample of M7--L8 dwarfs within 20 pc using the 2MASS Second Data Release. With this dataset, we present the first robust measurement of the luminosity function of objects that span the stellar/brown dwarf boundary. In addition, we have doubled the number of ultracool dwarfs known within 20 pc. I will describe these results, summarize its implications on the mass function, and discuss the prospects for the future.
