277883 Basu           Discovered 2006 May 1 by P. A. Wiegert at Mauna Kea.
Shantanu Basu (b. 1964) is an American astrophysicist. He has performed numerical studies of star formation that have elucidated the effect of magnetic fields on cloud core and disk formation, and he was one of the originators of the Migrating Embryo model of circumstellar disk evolution.
