Two New Variable Hot DQ Stars
B. N. Barlow, B. H. Dunlap, R. Rosen +1
We have discovered periodic variations in the light curves of two hot DQ stars from the Sloan Digital Sky Survey, SDSS J220029.08-074121.5 and SDSS J234843.30-094245.3. These are t…
Deciphering the Pulsations of G 29-38 with Optical Time Series Spectroscopy
Susan E. Thompson, M. H. van Kerkwijk, J. C. Clemens
We present optical time series spectroscopy of the pulsating white dwarf star G29-38 taken at the Very Large Telescope (VLT). By measuring the variations in brightness, Doppler shi…
A Quantitative Non-radial Oscillation Model for the Subpulses in PSR B0943+10
R. Rosen, J. Christopher Clemens
In this paper, we analyze time series measurements of PSR B0943+10 and fit them with a non-radial oscillation model. The model we apply was first developed for total intensity meas…
