TOI-7475 spectroscopic follow up - detection of a massive hot Jupiter on an eccentric orbit
Joanna Pietrucha, Jakub Jerzy Tokarek, Mateusz Witczak +1
We present the first spectroscopic follow-up for TOI-7475, and report the detection of a planetary-mass companion. Transits with a period of 3.25 days were observed by TESS. The di…
Revisiting BV & BW Draconis: Detailed Study of Intriguing Multiple System
J. J. Tokarek, W. Dimitrov, M. Polińska +6
The BV & BW Draconis system is a unique coplanar system of two eclipsing contact binaries. The main objective of this study is to develop a model based on new observations. The onl…
Over a century of Ceti variability investigation
Śreniawska E., Kamiński K., Kamińska M. K. +2
We present results of a 2014-2018 campaign of radial velocity measurements of Ceti. Combining our determination of pulsation period with historical data we conclude that the mo…
Rotational modulation and single g-mode pulsation in the B9pSi star HD174356?
Z. Mikulasek, E. Paunzen, S. Huemmerich +19
Chemically peculiar (CP) stars of the upper main sequence are characterised by specific anomalies in the photospheric abundances of some chemical elements. The group of CP2 stars,…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
