Scientific paper

Among the ~6000 new white dwarfs (WDs) spectroscopically confirmed by the Sloan Digital Sky Survey (SDSS) are three cool DAs and two cool DBs within 1 of super-soft ROSAT All Sky Survey (RASS) sources. WDs at these relatively low temperatures (<23,000K) are not expected to be X-ray emitters, but the SDSS photometric and spectroscopic data fail to identify any other obvious optical counterparts to the RASS sources to the SDSS limits (g~23 mag in photometry). We propose 5 ksec XMM-Newton observations of these five SDSS WDs to obtain pinpoint X-ray positions and improved flux measures for these objects. If XMM data confirm that the five WDs are X-ray sources, they will be of great interest; in particular, theoretical work will be required to explain how such cool WDs can emit X rays.
