    Giant Black Hole Shreds and Swallows Helpless Star

    by Ken Croswell

    Some people seem born under an unlucky star. But some stars are equally unlucky themselves. Astronomers have spotted a star in another galaxy plunging toward a giant black hole and being ripped to shreds, sparking a flare so brilliant that observers detected it from a distance of 2.1 billion light-years. By watching the flare brighten and fade, scientists have achieved the unprecedented feat of reconstructing the life story of the doomed sun.

    Nice. Too bad the actual paper is behind a paywall.. couldn't find it on arxiv either. IIRC if such a tidal disruption event can be seen it put limits on the size of the black hole involved, I'd love to see what the paper says about that.

    Thanks. I didn't see it in the list when I searched for all recent Gezari papers. Maybe it was still being processed.

    ETA: Here's a previous thread on TDE's, with some great links.
