| Description | 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 are still contracting. With an age of 10 Ma, K2-33 b is the first system discovered during this crucial state of the planet.s evolution that can be thoroughly studied due to is close proximity to the Sun. Furthermore, the Neptune-sized planet could exhibit close to fatal mass-loss rates that could remove its complete gaseous envelope. We propose to determine the host star.s X-ray properties and the current planetary mass-loss rate, which will allow to reconstruct the total fraction of mass lost by this young planet since its formation. |

| 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. |
