XMM-Newton observations of the complex spin pulse of the intermediate polar PQ Geminorum
XMM-Newton observations of the complex spin pulse of the intermediate polar PQ Geminorum
The intermediate polar PQ Geminorum shows a complex pulsation, caused by a spinning white dwarf, which varies markedly with wavelength. We report XMM–Newton observations, including the soft and hard X-ray bands and the first ultraviolet light curves of this star. We update the ephemeris for PQ Gem allowing us to …
