A Newly Discovered SU UMa-Type Dwarf Nova, HS 1449+6415
D. Nogami, D. Engels, B. T. Gaensicke +3
We report time-resolved photometric observations of the Hamburg Quasar Survey-selected dwarf nova HS 1449+6415 (= RX J1450.5+6403) during the interval from JD 2451672 to 2451724. D…
The response of a dwarf nova disc to real mass transfer variations
M. R. Schreiber, B. T. Gaensicke, F. V. Hessman
We present simulations of dwarf nova outbursts taking into account realistic variations of the mass loss rate from the secondary. The mass transfer variation has been derived from…
BeppoSAX observations of AM Herculis in intermediate and high states
G. Matt, D. de Martino, B. T. Gaensicke +5
Temporal and spectral analyses from BeppoSAX observations of AM Her performed during both an intermediate and a high state are presented and discussed. Optical observations taken a…
HS0907+1902: a new 4.2hr eclipsing dwarf nova
B. T. Gaensicke, R. E. Fried, H. -J. Hagen +5
We report on follow-up spectroscopy and photometry of the cataclysmic variable candidate HS0907+1902 selected from the Hamburg Quasar Survey. B, V, and R photometry obtained during…
