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 (~0.001 solar masses)? And with what efficiency? Is there a low-mass cutoff to star formation? These are important questions with broad astrophysical impact..
