It is one of the most detailed looks yet at the phenomenon, called a tidal disruption event (or TDE), and the first for NASA’s Transiting Exoplanet Survey Satellite (more commonly called TESS.)

The milestone was reached with the help of a worldwide network of robotic telescopes headquartered at The Ohio State University called ASAS-SN (All-Sky Automated Survey for Supernovae). Astronomers from the Carnegie Observatories, Ohio State and others published their findings today in The Astrophysical Journal.

“We’ve been closely monitoring the regions of the sky where TESS is observing with our ASAS-SN telescopes, but we were very lucky with this event in that the patch of the sky where TESS is continuously observing is small, and in that this happened to be one of the brightest TDEs we’ve seen,” said Patrick Vallely, a co-author of the study and National Science Foundation Graduate Research Fellow at Ohio State. “Due to the quick ASAS-SN discovery and the incredible TESS data, we were able to see this TDE much earlier than we’ve seen others — it gives us some new insight into how TDEs form.”

Tidal disruption events happen when a star gets too close to a black hole. Depending on a number of factors, including the size of the star, the size of the black hole and how close the star is to the black hole, the black hole can either absorb the star or tear it apart into a long, spaghetti-like strand.
