Description The exciting discovery that Prox Cen is orbited by a potentially habitable Earth-size planet has motivated us to examine the next two nearest known HZ planets. X-ray observations (40+40 ks) are requested of Kapteyn s Star (KS - M1.5 V; 3.9pc) & Wolf 1061 (M3 V; 4.3pc). KS hosts a mid-HZ super-earth: Kapteyn b (virgul4.8 Me). Wolf 1061 hosts 3 super earths - one within the HZ: Wolf 1061c (virgul4.3 Me). These planets are of sufficiently low mass (< 5Me) that they may be rocky. Unlike Prox Cen which has extensive X-ray observations (>400 ks), the X-ray properties of these stars are poorly constrained. As shown in our Prox b study (Ribas et al. 2016), the host star s X-ray (& UV) radiation strongly affects (via photoionization-photodissociation) the planet s atmosphere, water inventory & habitability.

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.
