Description ASASSN-14li is a nearby (90 Mpc) X-ray bright (~10^-11 erg-s-cm^2 at peak) multiwavelength transient which resulting from the tidal disruption of a star by a massive (~10^6 Msun) black hole in a ~10^9 Msun galaxy in late 2014. This presents a once-per-decade opportunity to study the multi-wavelength evolution of a non-relativistic, X-ray bright tidal disruption event at high signal-to-noise in X-rays, ultraviolet and radio. We propose a comprehensive 3-cycle Chandra, XMM-Newton, HST spectroscopy, and VLA program to study the evolution of this event over the next three years as it fades. Chandra presents the earliest opportunity for deep X-ray observations of this likely "Rosetta Stone" for tidal disruption events.

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.
