PPT-CWISEP J1935─1546: An Extremely Cold Brown Dwarf in the Solar Neighborhood Discovered

CatWISE Federico Marocco NPP Fellow Science Question How can star formation create stars of extremely low mass down to a few times the mass of Jupiter 0001 solar masses And with what efficiency Is there a lowmass cutoff to star formation These are important questions with broad astrophysical impact. Overview. Co-op basics. How a co-op works. Benefits of going solar as a group. MD SUN’s experience implementing co-ops. What a partnership would look like. Process Overview. Benefits of a co-op. Help a group of neighbors go solar together. To Be A Planet, Or Not To Be?. Physical Characteristics . 5 - Recognized Dwarf Planets. Ceres, Pluto, . Haumea. , . Makemake. , Eris.
