Supernova (SN) 2010jl is a bright Type IIn SN shown to have X-ray emission earlyon. Our three {it Chandra} ACIS-S observations taken at 58 days, one year and 20months after the SN discovery show dramatically different spectra and strongevolution of the X-ray absorption. The spectra indicate high temperatures andhigh absorbing column densities. This is the first time an externalcircumstellar X-ray absorption has been clearly observed in a SN, giving us arare opportunity to follow the evolution of the external column density andobtain unique information on circumstellar structure and the shock interaction.In this proposal we request 80 ks of XMM-Newton EPIC-PN and MOS observations ofSN 2010jl at two epochs.

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.
