IP Pegasi in outburst: Echelle spectroscopy & Modulation Doppler Tomography
C. Papadaki, H. M. J. Boffin, D. Steeghs
We analyse a unique set of time-resolved echelle spectra of the dwarf nova IP Peg, obtained at ESO's NTT with EMMI. The dataset covers the wavelength range of 4000-7500A and shows…
Photometric study of selected cataclysmic variables II. Time-series photometry of nine systems
C. Papadaki, H. M. J. Boffin, V. Stanishev +3
We present time-series photometry of nine cataclysmic variables: EI UMa, V844Her, V751 Cyg, V516 Cyg, GZ Cnc, TY Psc, V1315 Aql, ASAS J002511+1217.12, V1315 Aql and LN UMa. The obs…
V2051 Oph after superoutburst: out-of-plane material and the superhump light source
Christina Papadaki, Henri M. J. Boffin, Danny Steeghs +1
We performed a detailed spectroscopic analysis of the dwarf nova V2051 Oph at the end of its 1999 superoutburst. We studied and interpreted the simultaneous behaviour of various em…
3D Gasdynamic Modelling of the Changes in the Flow Structure During Transition From Quiescent to Active State in Symbiotic Stars
M. Mitsumoto, B. Jahanara, T. Matsuda +6
The results of 3D modelling of the flow structure in the classical symbiotic system Z~Andromedae are presented. Outbursts in systems of this type occur when the accretion rate exce…
Simultaneous Doppler maps of IP Peg in outburst
C. Papadaki, H. M. J. Boffin, D. Steeghs
IP Pegasi is an eclipsing dwarf nova lying above the period gap with an orbital period of 3.8h. It is the first cataclysmic variable to show evidence of spiral arms in its accretio…
Accretion Disc Evolution in DW Ursae Majoris: A Photometric Study
V. Stanishev, Z. Kraicheva, H. M. J. Boffin +3
We present an analysis of CCD photometric observations of the eclipsing novalike cataclysmic variable DW UMa obtained in two different luminosity states: high and intermediate. The…
