Rebassa-Mansergas, A., Gaensicke, B. T., Rodriguez-Gil, P., Schreiber, M. R., Koester, D.
We present a detailed analysis of 101 white dwarf-main sequence binaries (WDMS) from the Sloan Digital Sky Survey (SDSS) for which multiple SDSS spectra are available. We detect significant radial...
SDSS J233325.92+152222.1 and the evolution of intermediate polars (2007)
Southworth, John, Gaensicke, B. T., Marsh, T. R., De Martino, D., Aungwerojwit, A.
Intermediate polars (IPs) are cataclysmic variables which contain magnetic white dwarfs with a rotational period shorter than the binary orbital period. Evolutionary theory predicts that IPs with...
