Analysis of photometric and spectroscopic variability of red supergiant Betelgeuse
Daniel Jadlovsky, Jiri Krticka, Ernst Paunzen +1
Betelgeuse is a pulsating red supergiant whose brightness is semi periodically variable and in February 2020 reached a historical minimum, the Great Dimming. The aims of this study…
Searching for shell stars in LAMOST DR4 by probing the Fe 42 multiplet lines
S. Huemmerich, E. Paunzen, K. Bernhard
Shell stars, in particular the cooler ones, often do not show conspicuous Balmer-line emission and may consequently be missed in surveys that specifically search for emission signa…
The detection of magnetic chemically peculiar stars using Gaia BP/RP spectra
E. Paunzen, M. Prisegen
The magnetic chemically peculiar (mCP) stars of the upper main sequence are perfectly suited to studying the effects of rotation, diffusion, mass-loss, accretion, and pulsation in…
HD 60431, the CP2 star with the shortest rotational period -- Physical parameters and period analysis
Z. Mikulasek, E. Semenko, E. Paunzen +5
CP2 stars show periodic photometric, spectroscopic, and magnetic variations with the rotational period. They are generally slow rotators, with rotational periods exceeding half a d…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
Analysis of eight magnetic chemically peculiar stars with rotational modulation
O. Kobzar, V. Khalack, D. Bohlender +9
Since the end of 2018, the Transiting Exoplanet Survey Satellite (TESS) has provided stellar photometry to the astronomical community. We have used TESS data to study rotational mo…
