The Intermediate Polar EI UMa: A Pre-Polar Cataclysmic Variable
Tamara W. Reimer, William F. Welsh, Koji Mukai +1
We present optical and X-ray time-series photometry of EI UMa that reveal modulation at 746 and 770 s, which we interpret as the white dwarf spin and spin-orbit sidebands. These de…

On Using the Rossiter Effect to Detect Terrestrial Planets
W. F. Welsh, J. A. Orosz
We explore the possibility that the transit signature of an Earth-size planet can be detected in spectroscopic velocity shifts via the Rossiter effect. Under optimistic but not unr…

Dynamical constraints on the component masses of the cataclysmic variable WZ Sge
D. Steeghs, S. Howell, C. Knigge +3
We present phase-resolved spectroscopy of the short period cataclysmic variable WZ Sge obtained with the Hubble Space Telescope. We were able to resolve the orbital motion of a num…
