A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs

Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72

We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-res…

The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs

J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85

A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
