MOCCA: Dynamics and evolution of binary stars of multiple stellar populations in tidally filling and underfilling globular star clusters
Arkadiusz Hypki, Mirek Giersz, Jongsuk Hong +4
We present an upgraded version of the \MOCCA code for the study of dynamical evolution of globular clusters (GCs) and its first application to the study of evolution of multiple st…
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…
Increasing supercycle lengths of active SU UMa-type dwarf novae
M. Otulakowska-Hypka, A. Olech
We present observational evidence that supercycle lengths of the most active SU UMa-type stars are increasing during the past decades. We analysed a large number of photometric mea…
On supercycle lengths of active SU UMa stars
M. Otulakowska-Hypka, A. Olech
We performed a detailed analysis of extensive photometric observations of a sample of most active dwarf novae, that is SU UMa stars which are characterised by supercycle lengths sh…
IX Draconis - a curious ER UMa-type dwarf nova
M. Otulakowska-Hypka, A. Olech, E. de Miguel +3
We report results of an extensive world-wide observing campaign devoted to a very active dwarf nova star - IX Draconis. We investigated photometric behaviour of the system to deriv…
The expanding dusty bipolar nebula around the nova V1280 Sco
Olivier Chesneau, E. Lagadec, M. Otulakowska-Hypka +15
V1280 Sco is one of the slowest dust-forming nova ever historically observed. We performed multi-epoch high-spatial resolution observations of the circumstellar dusty environment o…
