Mass, Age, and Composition of a Brown Dwarf Revealed
April 7, 2016
NASA Keck PI Justin Crepp (Univ. of Notre Dame) is the first author on a paper that calculates the mass of a brown dwarf (HD 4747 B) directly using observations of its orbit. These direct measurements will provide a testbed to help refine brown dwarf models. NExScI manages NASA's portion of time on the Keck telescopes.
