New insight on the rapid rotator HD 199178

Session 1 Stellar Structure and Evolution

Abstract

Optical spectra were obtained of the rapidly rotating star HD 199178 to analyze the Hα profile. Excess emission was derived by subtracting a comparison star spectrum. The Hα line fluxes variability is stressed together with the discussion of this and previous data in the context of the surface phenomena for the FK Com family of stars.
