Abstract	The time available for planet formation is limited by the lifetime of thecircumstellar disks and it can be measured to 2 Myr in young stellar clusters bycounting up the number of disk-bearing and disk-less stars for clusters ofdifferent ages. However, Pfalzner (2014) claim that to be a gross underestimate.We propose to test this hypothesis by an 80 ks observation in the star formingregion IC 1396 using the large field of view of XMM-Newton. If true, we willfind an extended population of cluster members that should spread beyond theradius covered by previous observations of clusters in this age range. Thiswould prove that the time scale for planet formation is several times longerthan known to date.

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.
