The symbiotic binary St 2-22: Orbital and stellar parameters and jet evolution following its 2019 outburst
Cezary Galan, Joanna Mikolajewska, Krystian Ilkiewicz +3
St 2-22 is a relatively poorly studied S-type symbiotic system that belongs to a small group of jet-producing systems as a result of disc accretion onto a white dwarf fed by its re…
The symbiotic recurrent nova V3890 Sgr: binary parameters and pre-outburst activity
J. Mikolajewska, K. Ilkiewicz, C. Galan +4
We present and analyze optical photometry and high resolution SALT spectra of the symbiotic recurrent nova V3890 Sgr at quiescence. The orbital period, P=747.6 days has been derive…
The surface brightness - colour relations based on eclipsing binary stars and calibrated with Gaia EDR3
D. Graczyk, G. Pietrzyński, C. Gałan +23
The surface brightness -- colour relation (SBCR) is a basic tool in establishing precise and accurate distances within the Local Group. Detached eclipsing binary stars with accurat…
