Periodic variable A-F spectral type stars in the northern TESS continuous viewing zone
M. Skarka, J. Žák, M. Fedurco +11
The goal of our study is to provide a reliable classification of variability of A-F stars brighter than 11 mag located in the northern TESS continuous viewing zone. We also aim at…
V680 Mon -- a young mercury-manganese star in an eclipsing heartbeat system
E. Paunzen, S. Huemmerich, M. Fedurco +3
Chemically peculiar stars in eclipsing binary systems are rare objects that allow the derivation of fundamental stellar parameters and important information on the evolutionary sta…
A photometric study of two neglected eclipsing binaries
V. Kudak, M. Fedurco, V. Perig +1
We present the first BVR photometry, period variation, and photometric light-curve analysis of two poorly studied eclipsing binaries V1321 Cyg and CR Tau. Observations were carried…
Pulsational properties of ten new slowly pulsating B stars
M. Fedurco, E. Paunzen, S. Hümmerich +2
We collected a sample of ten hitherto unidentified SPB stars with the aim of describing their pulsational properties and identifying pulsational modes. Photometric time series data…
A revisit to the enigmatic variable star 21 Comae
Ernst Paunzen, Gerald Handler, Przemyslaw Walczak +12
The magnetic chemically peculiar (Ap/CP2) star 21 Com has been extensively studied in the past, albeit with widely differing and sometimes contradictory results, in particular conc…
Double eclipsing binary system KIC 3832716
M. Fedurco, Š. Parimucha
In this paper we analyzed the light curve of the object KIC~3832716 observed during Kepler K1 mission. We showed that this previously known eclipsing binary is in fact quadruple sy…
Orbital parameters and evolutionary status of the highly peculiar binary system HD 66051
E. Paunzen, M. Fedurco, K. G. Helminiak +8
The spectroscopic binary system HD 66051 (V414 Pup) consists of a highly peculiar CP3 (HgMn) star and an A-type component. It also shows out-of-eclipse variability that is due to c…
Period variations of Algol-type eclipsing binaries AD And, TW Cas and IV Cas
S. Parimucha, P. Gajdos, V. Kudak +2
We present new analysis of O-C diagrams variations of three Algol-type eclipsing binary stars AD And, TW Cas and IV Cas. We have used all published minima times (including visual a…
