| Description | When a star is tidally disrupted by a supermassive black hole, the rapid accretion of the stellar debris may drive super-Eddington winds which. After a period of accretion rate decay, we expect the winds to shut off, drastically reducing the production of broad line emission and changing the evolution of the band-specific light curve across the spectrum. Spectroscopic monitoring of new tidal disruption events (TDEs) in the ultraviolet is the best place to observe this transition due to the persistence of a windless disk continuum. the lack of stellar contamination, and the wealth of high-ionization diagnostic lines that probe the relatively small TDE accretion structure. We propose to observe 5 TDEs over 3 epochs with monitoring UV spectroscopy and complementary X-ray and optical |

| 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. |
