Abstract TW Pictoris is the optical counterpart of the HEAO-1 X-ray source H0534-581 andhas been proposed as a candidate intermediate polar (IP). Yet optical and X-rayobservations have failed to reveal the spin modulation, the definingcharacteristic of an IP. If this is a non-magnetic nova-like variable instead,then it is by far the X-ray brightest member of this class. We therefore proposean XMM-Newton observation in an attempt to solve this mystery.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
