The tidal disruption of a star by a black hole provides a unique opportunity tostudy accretion physics. Recently, delayed radio flares have been discovered inseveral TDEs, peaking years after their optical emission has faded. Variousexplanations have been proposed, including off-axis jets entering our line ofsight, delayed accretion disk formation, or a state change in the accretionflow. To elucidate the origin(s) of these flares, it has become crucial toacquire radio and X-ray observations of these events at late-times (virgul months toyears post-discovery) to study this previously unexplored phase in the lifetimeof TDEs.

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.
