Stark-Broadened Profiles for Ionized Helium Lines Using Computer Simulations
Patrick Tremblay, Alain Beauchamp, Pierre Bergeron
We present new and improved calculations of Stark-broadened profiles for ionized helium, a key ingredient in the spectroscopic analysis of helium-atmosphere DO white dwarfs. Our ap…

Improved Stark Broadened Profiles for Neutral Helium Lines Using Computer Simulations
Patrick Tremblay, Alain Beauchamp, Pierre Bergeron +1
The study of Stark broadening of neutral helium lines, despite significant advances over recent decades, has not led to updated large grids of helium line profiles relevant to the…
