Spectroscopy of white dwarf stars observed by HETDEX.

Approximately 97% of all stars will become white dwarf stars at the end of their life cycles, making them excellent benchmarks for testing theories of stellar evolution. For the purposes of numerical modelling, they can be treated as simple objects composed of two structures that can be treated independently: a thin photosphere and a degenerate core. Large-scale surveys, such as the Sloan Digital Sky Survey, have spectroscopically observed more than 40,000 white dwarfs to date, providing a large sample to be used in the evaluation of these theoretical models. We use spectral data of white dwarf stars found in the Hobby-Eberly Telescope Dark Energy Experiment, in addition to parallax data from the Gaia space observatory, to determine effective temperature and surface gravity of this unique magnitude-limited sample.
