RR Pictoris: an old nova showing superhumps and QPOs
L. Schmidtobreick, C. Papadaki, C. Tappert +1
We present time-resolved V-photometry of the old nova RR Pic. Apart from the hump-like variability, the light curves show the strong flickering and random variation typical for RR…
NSV 13983: A New Dwarf Nova in the Period Gap
C. Contreras, C. Tappert
Aims. NSV 13983 is catalogued as a dwarf nova based on a reported outburst from 2005. The system has not yet been studied spectroscopically. We attempt to confirm its nature as a d…
The remarkable properties of the symbiotic star AE Circinus
R. E. Mennickent, J. Greiner, J. Arenas +4
We present new optical spectroscopy and photometry, 2MASS infrared observations and 24 years of combined AAVSO and AFOEV photometry of the symbiotic star candidate æ. The long-term…
The pre-cataclysmic variable, LTT560
C. Tappert, B. T. Gaensicke, L. Schmidtobreick +3
System parameters of the object LTT560 are determined in order to clarify its nature and evolutionary status. We apply time-series photometry to reveal orbital modulations of the l…
K-band spectroscopy of pre-cataclysmic variables
C. Tappert, B. T. Gaensicke, L. Schmidtobreick +2
We have taken K-band spectroscopy of a sample of 13 pre-CVs in order to examine them for anomalous chemical abundances. In particular, we study the strength of the 12CO and 13CO ab…
