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…
Testing the disk instability model of cataclysmic variables
Guillaume Dubus, Magdalena Otulakowska-Hypka, Jean-Pierre Lasota
The disk instability model attributes the outbursts of dwarf novae to a thermal-viscous instability of their accretion disk, an instability to which nova-like stars are not subject…
SY Mus - search for physical parameters
Aleksandra Leśniewska, Magdalena Otulakowska-Hypka, Joanna Mikołajewska +1
This is a preliminary analysis of the orbital parameters of the well known eclipsing symbiotic binary, SY Muscae. It is a system composed of a white dwarf (WD) and a red giant (RG)…
Statistical analysis of properties of dwarf novae outbursts
Magdalena Otulakowska-Hypka, Arkadiusz Olech, Joseph Patterson
We present a statistical study of all measurable photometric features of a large sample of dwarf novae during their outbursts and superoutbursts. We used all accessible photometric…
