Abstract	We ask for a new observation of the gamma Cassiopeiae-like X-ray star HD 161103to check for the presence of the 3.2 ks modulation seen in the previousXMM-Newton observation (in 2004). If the modulation is observed once again withthe same period, it would support the origin of the mysterious X-ray emission ofthe whole class of gamma Cas-like stars as being due to an accreting compactobject, presumably a white dwarf.

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.
