Isolated Brown dwarfs at the Exoplanet Mass Boundary

Jacqueline Faherty

Carnegie Institute DTM

Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should be studied in concert. Similarities between the peculiar shaped H band, near and mid-IR photometry as well as location on color magnitude diagrams provide important clues about how to extract physical properties of planets from current brown dwarf observations. In this talk I will discuss systems newly assigned to 10-150 Myr nearby moving groups, highlight the diversity of this uniform age-calibrated brown dwarf (or planetary mass) sample, and reflect on their implication for understanding current and future planetary data.
