The nature of 1WGA J1958.2+3232: A new intermediate polar
We present low and intermediate resolution spectroscopy of the optical counterpart to the recently discovered pulsating X-ray source 1WGA J1958.2+3232. The presence of strong H i, He i and He ii emission lines together with the absence of absorption features rules out the possibility that the object is a massive star, as had recently been suggested. The observed X-ray and optical characteristic...
متن کاملRx J0744{52: a Probable New Intermediate Polar
We present optical and X-ray data of the Cataclysmic Variable RX0744{52 discovered using ROSAT by Motch et al. High resolution spectroscopy centred on the H line indicates a probable orbital period of 3.60 hrs. From its distance (obtained using polarimetry), its X-ray luminosity, its X-ray colour and its X-ray/UV+Opt ratio, we suggest that RX0744{52 is an new Intermediate Polar. The absence of ...
متن کاملLeonis a superoutbursting intermediate polar ?
We present an XMM-Newton analysis of the cataclysmic variable T Leo. The X-ray light curve shows sinusoidal variation on a period Px equal to 0.89+0.14 −0.10 times the previously spectroscopically determined orbital period. Furthermore, we find a signal in the power spectrum at 414 sec that could be attributed to the spin period of the white dwarf. If true, T Leo would be the first confirmed su...

متن کاملHS 0943 + 1404 , a true intermediate polar ⋆
We have identified a new intermediate polar, HS 0943+1404, as part of our ongoing search for cataclysmic variables in the Hamburg Quasar Survey. The orbital and white dwarf spin periods determined from time-resolved photometry and spectroscopy are P orb ≃ 250 min and Pspin = 69.171 ± 0.001 min, respectively. The combination of a large ratio Pspin/P orb ≃ 0.3 and a long orbital period is very un...
