FS Auriga Field

Star field with cataclysmic variable star FS Auriga and our newly discovered eclipsing binary (2007 AJ, 133, 1944,
2011 AJ, 141, 124). Try and find the cataclysmic variable, its accretion disk puts out lots of UV lightmaking it appear as an extremely blue star right of center.

Supernova Before Supernova After
Observations of a galaxy before and after one of its star's went supernova.The light from the supernova almost outshines the galaxy of several billion stars itself.

WZ Sge
Eclipses imbedded in superhumps of cataclysmic variable WZ Sagittea during a 2001 superoutburst monitoring campaign with the Center for Backyard Astrophysics CBA, (2002 PASP 114, 721).

V1159 Orionis

Observations of outbursts, superoutburst and superhumps in cataclysmic variable V1159 Orionis over its ~45 day cycle (1999 ApJ, 521, 362)
