HD 183986: a high-contrast SB2 system with a pulsating component
Martin Vaňko, Theodor Pribulla, Pavol Gajdoš +7
There is a small group of peculiar early-type stars on the main sequence that show different rotation velocities from different spectral lines. This inconsistency might be due to t…
Secular changes in the orbits of the quadruple system VW LMi
T. Pribulla, E. Puha, T. Borkovits +8
VW~LMi is the tightest known quadruple system with 2+2 hierarchy. It consists of a W UMa-type eclipsing binary (P12 = 0.47755 days) and another detached non-eclipsing binary (P34 =…
Periodic transit timing variations and refined system parameters of the exoplanet XO-6b
Zoltán Garai, Theodor Pribulla, Richard Komžík +3
Only a few exoplanets are known to orbit around fast rotating stars. One of them is XO-6b, which orbits an F5V-type star. Shortly after the discovery, we started multicolor photome…
Affordable echelle spectroscopy of the eccentric HAT-P-2, WASP-14 and XO-3 planetary systems with a sub-meter-class telescope
Z. Garai, T. Pribulla, Ľ. Hambálek +6
A new off-shelf low-cost echelle spectrograph was installed recently on the 0.6m telescope at the Stará Lesná Observatory (Slovakia). In this paper we describe in details the radia…
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…
Photometric Study of Two Recently Discovered Variable Stars in the Field of BS Cas
Natalia A. Virnina, Radek Kocian, Lubomir Hambalek +3
Two recently discovered variable stars (CzeV134 = GSC 3682 0018 = USNO-A2.0 1425-1870026 and CzeV135 = GSC 3682 2051 = USNO-A2.0 1425-1825909 = V1094 Cas), which have been identifi…
