White Dwarf Atmospheres

We study X-ray grating spectra of extremely hot, hydrogen burning whte dwarfs atmospheres. Using the X-ray grating spectra onboard the Chandra and XMM-Newton X-ray satellites, we investigate their winds of nebular ejecta. We hope to measure the temperature, mass and chemical composition of the white dwarfs in this stage - and thus understand whether they may become supernovae.
