Chemical abundance analysis of symbiotic giants. Metallicity and CNO abundance patterns in 14 northern S-type systems
Cezary Gałan, Joanna Mikołajewska, Kenneth H. Hinkle +1
In previous works, we computed abundances for the red giant in nearly four dozen S-type symbiotic systems (SySt). The abundances provide information about metallicity, evolutionary…
The Araucaria Project: Improving the cosmic distance scale
The Araucaria Project, :, G. Pietrzyński +21
The book consists of a number of short articles that present achievements of the Araucaria members, collaborators, and friends, in various aspects of distance determinations and re…
Evolved eclipsing binary systems in the Galactic bulge: Precise physical and orbital parameters of OGLE-BLG-ECL-305487 and OGLE-BLG-ECL-116218
K. Suchomska, D. Graczyk, C. Gałan +17
Our goal is to determine, with high accuracy, the physical and orbital parameters of two double-lined eclipsing binary systems, where the components are two giant stars. We also ai…
Surface brightness-colour relations of dwarf stars from detached eclipsing binaries -- I. Calibrating sample
D. Graczyk, G. Pietrzyński, C. Galan +19
Surface brightness -- colour relations (SBCRs) are very useful tools for predicting the angular diameters of stars. They offer the possibility to calculate very precise spectrophot…
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…
