Time-resolved spectroscopy of the sdBV V338 Serpentis
Abstract
We obtained 1955 high-resolution spectra of the high-amplitude pulsating subdwarf B star V338 Ser with the FIES spectrograph at the 2. 5 m Nordic Optical Telescope covering 4 full nights in May-June 2009. Here we present the first results from phase-folding the data on the main pulsation mode, as revealed by simultaneous B-band photometry obtained with the Mercator 1. 25 m and Baker 0. 4 m telescopes. We compare the results with a sample line-profile model produced with LTE atmospheres and bruce+kylie.
