Finding the Instability Strip for Accreting Pulsating White Dwarfs from HST and Optical Observations
Paula Szkody, Anjum Mukadam, Boris T. Gansicke +9
Time-resolved low resolution Hubble Space Telescope ultraviolet spectra together with ground-based optical photometry and spectra are used to constrain the temperatures and pulsati…
V371 Per - A Thick-Disk, Short-Period F/1O Cepheid
Patrick Wils, Arne A. Henden, Stelios Kleidis +2
V371 Per was found to be a double-mode Cepheid with a fundamental mode period of 1.738 days, the shortest among Galactic beat Cepheids, and an unusually high period ratio of 0.731,…
The pulsation spectrum of VX Hydrae
M. R. Templeton, G. Samolyk, S. Dvorak +3
We present the results of a two-year, multisite observing campaign investigating the high-amplitude delta Scuti star VX Hydrae during the 2006 and 2007 observing seasons. The final…
The Behavior of Novae Light Curves Before Eruption
Andrew C. Collazzi, Bradley E. Schaefer, Limin Xiao +4
In 1975, E. R. Robinson conducted the hallmark study of the behavior of classical nova light curves before eruption, and this work has now become part of the standard knowledge of…
Polarimetry and the Long Awaited Superoutburst of BZ UMa
A. Price, J. Masiero, A. A. Henden +18
BZ UMa is a cataclysmic variable star whose specific classification has eluded researchers since its discovery in 1968. It has outburst and spectral properties consistent with both…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae
Taichi Kato, Akira Imada, Makoto Uemura +60
We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications. In many systems, the evolution of superhum…
