Abstract	We propose to observe a sample of late A to early F stars with XMM-Newton tosystematically investigate coronal properties at the onset of stellar magneticactivity in X-rays. These stars feature a thin or localized outer convectionzone and have been only poorly explored by modern X-ray instruments. We focus onnearby, presumably single main-sequence stars with well known stellarparameters. The aim is to study the interplay between developing convectiveenvelope and rotation, thereby driving a stellar dynamo mechanism and generatingcoronal X-ray emission.

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.
