Watch A Sun-Sized Star Ripped Apart By A Supermassive Black Hole noting Ohio State Astronomers Capture Black Hole Shredding Star | WOSU Radio observed with the All-Sky Automated Survey for Supernovae (ASAS-SN): ASAS-SN's Homepage
TESS Spots Its 1st Star-shredding Black Hole | NASA - the event:
ASASSN-19bt
Discovery and Early Evolution of ASASSN-19bt, the First TDE Detected by TESS - IOPscience - journal article
The event was first noted by an ASAS-SN astronomer, Thomas Holoien, on 2019 Jan 29. The planet-hunting telescope TESS also saw it, first observing it on Jan 21. TESS accumulates its data, then downloads it in a big burst when it's closest to the Earth.
This event was then observed with some other telescopes, and it reached peak brightness on Mar 4.
The star was likely a Sun-like one, and it was disrupted as it passed close to a galaxy's central black hole. The galaxy: 2MASX J07001137-6602251 in constellation Volans, about 375 million light-years / 110 megaparsecs away. The BH likely had a mass of around 6 million solar masses.
