James "Gerbs" Bauer (born 1968 in Michigan, USA) is an American astronomer who studies comets and related bodies.
[2] He also observed the aftermath of the Deep Impact probe's collision with comet Tempel 1.
[3][4] Comet Tempel-Tuttle was recovered on March 4, 1997 by Karen Meech, Olivier Hainaut and James Bauer at the University of Hawai`i.
At the time it was very faint (22.5 mag), but the recovery proved that it was returning on schedule and that its orbit was very well determined.
[6] His analysis of the images of comet Hartley 2 taken by the WISE spacecraft revealed that the object was shedding mass.
