Abstract	Stellar high-energy emission powers strong evaporation in close-in planets.Directly after clearance of the protoplanetary disk, planets are most affected,because of the high activity of young stars and because the young planets arestill contracting. With an age of 10 Ma, K2-33 b is the first system discoveredduring this crucial state of the planets evolution that can be thoroughlystudied due to is close proximity to the Sun. Furthermore, the Neptune-sizedplanet could exhibit close to fatal mass-loss rates that could remove itscomplete gaseous envelope. We propose to determine the host stars X-rayproperties and the current planetary mass-loss rate, which will allow toreconstruct the total fraction of mass lost by this young planet since its formation.

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.
