Spectral binaries of brown dwarfs

Screen shot 2013-08-22 at 2.02.36 AMHow do brown dwarfs form? Some theories point to a star-like birth, accreting material from a molecular cloud, while some others point to a planet-like formation from a pre-stellar disk. Either way, the essential mechanisms for brown dwarf formation remain under debate by theorists. Given the astronomical timelines of star formation (1-10 million years), we cannot witness the formation process in action, but we can study its consequences on the statistical properties of the systems created.

14921768345_5d3ac9a592_z

Cool Star Lab undergraduates participated en masse at the 2014 Summer Undergraduate Research Conference  (SURC) on August 14th.  Christian Aganze, Mike Lopez, Rosalinda Lopez, Caleb Choban, and Kieran Berton each presented their summer’s work in the Astrophysics session, moderated by PI Adam Burgasser. Morehouse-UCSD Physics Bridge Fellows Jeremy Ariche and Saidou Ngaide also presented in this session. Melisa Tallis and Morehouse Fellow Julian Pilate-Hutcherson, who worked in the Shpyrko Lab this summer, presented in the parallel Physics & Engineering session; Jarrhett Butler, another Morehouse Fellow, presented in the Biophysics session.  This was the first time Astrophysics had its own session at the SURC, and the room was filled with astronomy fans and proud mentors.

Congratulations to everyone on a successful summer of research!
