New Pulsating DB White Dwarf Stars from the Sloan Digital Sky Survey (2008)
Nitta, A., Kleinman, S. J., Krzesinski, J., Kepler, S. O., Metcalfe, T. S., Mukadam, Anjum S., ...
We are searching for new He atmosphere white dwarf pulsators (DBVs) based on the newly found white dwarf stars from the spectra obtained by the Sloan Digital Sky Survey. DBVs pulsate at hotter...
Discovery of two new accreting pulsating white dwarf stars (2007)
Mukadam, Anjum S., Gänsicke, B. T., Szkody, P., Aungwerojwit, A., Howell, Steve B., Fraser, O. J., ...
We report the discovery of two new accreting pulsating white dwarf stars amongst the cataclysmic variables of the Sloan Digital Sky Survey: SDSSJ074531.91+453829.5 and SDSSJ091945.10+085710.0. We...
Mean ZZ Ceti pulsation period gauges stellar temperature (2006)
Mukadam, Anjum S., Montgomery, M. H., Kim, A., Winget, D. E., Kepler, S. O., Clemens, J. C.
The mean pulsation period of ZZ Ceti stars increases with decreasing effective temperature as we traverse from the blue to the red edge of the instability strip. This well-established correlation...
Measuring the evolution of the most stable optical clock G 117-B15A (2005)
Kepler, S. O., Costa, J. E. S., Castanheira, B. G., Winget, D. E., Mullally, Fergal, Nather, R. E., ...
We report our measurement of the rate of change of period with time dP/dt for the 215 s periodicity in the pulsating white dwarf G 117-B15A, the most stable optical clock known. After 31 years of...
Ensemble Characteristics of the ZZ Ceti stars (2005)
Mukadam, Anjum S., Montgomery, M. H., Winget, D. E., Kepler, S. O., Clemens, J. C.
We present the observed pulsation spectra of all known non-interacting ZZ Ceti stars (hydrogen atmosphere white dwarf variables; DAVs) and examine changes in their pulsation properties across the...
Re-defining the Empirical ZZ Ceti Instability Strip (2004)
Mukadam, Anjum S., Winget, D. E., Von Hippel, Ted, Montgomery, M. H., Kepler, S. O., Costa, A. F. M.
We use the new ZZ Ceti stars (hydrogen atmosphere white dwarf variables; DAVs) discovered within the Sloan Digital Sky Survey (Mukadam et al. 2004) to re-define the empirical ZZ Ceti instability...
A CCD Time-Series Photometer (2003)
Nather, R. E., Mukadam, Anjum. S.
We describe a high speed time-series CCD photometer for the prime focus of the 82-in (2.1 m) telescope at McDonald Observatory, and summarize the observational results we have obtained since it was...
