Automatic classification of eclipsing binary stars using deep learning methods
Michal Čokina, Viera Maslej-Krešňáková, Peter Butka +1
In the last couple of decades, tremendous progress has been achieved in developing robotic telescopes and, as a result, sky surveys (both terrestrial and space) have become the sou…
Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070
Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49
How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…
ELISa: A new tool for fast modelling of eclipsing binaries
Michal Čokina, Miroslav Fedurco, Štefan Parimucha
We present a new, fast, and easy to use tool for modelling light and radial velocity curves of close eclipsing binaries with built-in methods for solving an inverse problem. The ma…
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…
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…
On the nature of the candidate T-Tauri star V501 Aurigae
M. Vaňko, G. Torres, L. Hambálek +18
We report new multi-colour photometry and high-resolution spectroscopic observations of the long-period variable V501 Aur, previously considered to be a weak-lined T-Tauri star bel…
Optical flare activity in the low-mass eclipsing binary GJ~3236
S. Parimucha, P. Dubovsky, M. Vanko +1
We present our observations of the low-mass eclipsing binary GJ~3236. We have analyzed a phased light-curve and confirmed previously determined fundamental parameters of the…
Follow-up photometry of TrES-3
M. Vanko, G. Maciejewski, M. Jakubik +7
We present new observations of the transiting system TrES-3 obtained from 2009 to 2011 at several observatories. The orbital parameters of the system were re- determined and a new…
The DWARF project: Eclipsing binaries - precise clocks to discover exoplanets
T. Pribulla, M. Vaňko, M. Ammler - von Eiff +53
We present a new observational campaign, DWARF, aimed at detection of circumbinary extrasolar planets using the timing of the minima of low-mass eclipsing binaries. The observation…
SPHOTOM -- Package for an Automatic Multicolour Photometry
S. Parimucha, M. Vanko, P. Miklos
We present basic informations about package SPHOTOM for an automatic multicolour photometry. This package is in development for a creation of photometric pipe-line, which we plan t…
VW LMi: tightest quadruple system known. Light-time effect and possible secular changes of orbits
T. Pribulla, D. Baludansky, P. Dubovsky +4
Tightest known quadruple systems VW LMi consists of contact eclipsing binary with P_12 = 0.477551 days and detached binary with P_34 = 7.93063 days revolving in rather tight, 355.0…
Multiwavelength evidence for a 15-year periodic activity in the symbiotic nova V1016 Cygni
S. Parimucha, D. Chochol, T. Pribulla +2
The ~15.1 years period found in the long-term UBV photoelectric and photographic photometry of the symbiotic nova V1016 Cyg is detected also in the (J-K) colour index and in the UV…
