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…
Atomic gas properties at the positions of supernovae Type Ia, II, and Ib/c
Bruno Šlaus, Natalia Gotkiewicz, Michał J. Michałowski +6
Understanding which stars explode as which type of supernovae (SNe) is crucial to measure their contribution to the metal production and feedback halting star formation. Most of th…
HI and CO spectroscopy of the unusual host of GRB 171205A: A grand design spiral galaxy with a distorted HI field
A. de Ugarte Postigo, M. Michalowski, C. C. Thoene +22
GRBs produced by the collapse of massive stars are usually found near the most prominent star-forming regions of star-forming galaxies. GRB 171205A happened in the outskirts of a s…
Recent humps and superhumps observations and an estimation of outburst parameters of the AM CVn star CR Boo
Daniela Boneva, Radoslav Zamanov, Svetlana Boeva +4
We present our observational results of AM CVn star CR Boo in the UBVR bands. Our observational campaign includes data obtained over 5 nights with the National Astronomical Observa…
NGC 2770: high supernova rate due to interaction
Michał J. Michałowski, Christina Thöne, Antonio de Ugarte Postigo +6
Galaxies which hosted many core-collapse supernovae (SN) explosions can be used to study the conditions necessary for the formation of massive stars. NGC 2770 was dubbed a SN facto…
