Title

Identifying binary brown dwarf systems in HST archival data

Abstract

    Observations of binary brown dwarfs show that they are brighter than current atmospheric and evolutionary models predict for their age. Discovering and observing binary brown dwarfs are important for making critical measurements of mass, age, and luminosity that can be used to place better constraints on current evolutionary models and lead to a better understanding of their evolution. When the light from a brown dwarf passes through the telescope the light is spread out in a pattern known as a point spread function (PSF). We are identifying possible binary brown dwarf systems by testing models of singular and binary PSF’s against HST archival data. The discovery of new binaries will be used to constrain models on star formation and binary fraction.
