Radial velocity survey & non-LTE line profile modelling

Using state-of-the-art non-LTE model atmospheres from two different codes, the student will model non-LTE Balmer line cores, and determine rotational velocities in conjunction with stellar parameters of a sample of young white dwarf stars observed on 1999 October 3-11 and November 10-17 with the 74" telescope. The project involves comparing different numerical schemes and testing those schemes with real data.
