Title The onset of magnetic activity in X-rays - From late A to early F stars


DOI https://doi.org/10.5270/esa-tu9imlb
Author Dr Jan Robrade
Description We propose to observe a sample of late A to early F stars with XMM-Newton to
systematically investigate coronal properties at the onset of stellar magnetic
activity in X-rays. These stars with a thin or localized outer convection zone,
have been only poorly explored by modern X-ray instruments. This study focusses
on nearby, presumably single main-sequence stars with well known stellar
parameters to study the interplay between developing convective envelope and
rotation that drives a stellar dynamo mechanism and generates coronal X-ray

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
