What is recorded here?
Pan-STARRS and GALEX observed the rise and decay of PS1-10jh, a luminous ultraviolet and optical transient near the nucleus of a galaxy at redshift 0.1696. Follow-up spectroscopy showed broad ionized-helium emission without detected Balmer lines. The discovery team interpreted the light curve and line spectrum as a stellar tidal disruption; a later simulation-based analysis showed how a near-solar-composition star could also be consistent with the same observed data under a different emission model.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The tidal-disruption interpretation and the identity and composition of the disrupted star are inferences, not direct images of the disruption. The helium-rich core conclusion depends on line-emission assumptions; the alternative near-solar model also assumes a specific reprocessing geometry, simplified gas physics and disk-line scaling. Its simulations and fits reuse the original event data and do not independently observe a second event. The fitted disruption time, black-hole mass and stellar properties depend on the adopted stellar, accretion and radiation models. Chandra reported an X-ray upper limit, not a source detection. A 2015 photoionization analysis disputed the near-solar interpretation and favored helium-rich gas, but explicitly reported substantial numerical nonconvergence in parts of the high-density/high-flux regime and limitations of stationary-gas treatment. These differing models do not settle the source composition.

A well-observed ultraviolet and optical tidal-disruption candidate
