Research Interests

My principal research is focused on the study of cataclysmic variable stars:
Novae, Dwarf Novae, and Nova-like variables (An artist's conception is shown below).

Artist's visualization of a nova (NASA/Hardy)

This work includes the study of the fundamental properties of these systems in our own galaxy,
as well as the study of the spatial distribution and population of nova systems in nearby galaxies,
such as M31 (below).

The Andromeda Galaxy (M31) (Capella Obs.)

M31N 2008-12a, a rapidly-recurring recurrent nova in M31

An image of a portion Andromeda galaxy showing the position of M31N 2008-12a is shown below.
Its annual eruptions have have generated a large "super remnant", visible as an arc to the right of the
nova site (indicated by the green cross hairs).


Our group's recent work on the super remnant has been covered in SDSU NewsCenter.
