Maruša Žerjal


I am a PhD student of astrophysics at the University of Ljubljana under the supervision of Tomaž Zwitter. My main research interest is chromospherically active stars in the context of our Galaxy. I am a team member of the RAdial Velocity Experiment (RAVE survey), Hermes-GALAH spectroscopic survey and involved in the Gaia spectroscopic processing group as a developer of a radial velocity determination module with the use of binary masks for poor signal-to-noise spectra. I am a regular observer at the Asiago Observatory.

Other interests: stellar ages, stellar classification, peculiar stars, Galactic archaeology, stellar spectroscopy, radial velocities

Distribution of emission equivalent widths (EWIRT) in Ca II infrared triplet for active candidate stars (grey area), normal stars (which are assumed to be inactive; solid line) and pre-main sequence stars (selection is based on Simbad classification of RAVE stars; dashed line). The scale is logarithmic.
