IR spectroscopy of pre-cataclysmic binaries
C. Tappert, B. T. Gaensicke, R. E. Mennickent
We have taken near-infrared (JHK) spectroscopic data of a sample of pre-CVs, in order to examine them for signatures of nuclear evolution. Here we present preliminary results for t…

Is the old nova RW UMi (1956) an intermediate polar?
A. Bianchini, C. Tappert, H. Osborne +2
From photometric observations of the old nova RW UMi (1956) we have discovered the presence of five sub-orbital periodicities. The longest period, P1 = 54.4 min, always observed, c…
