Astronomers have discovered 18 new cases of black holes ripping up and devouring stars, more than doubling the number of known tidal disruption events found in the local universe.
<p>A<strong> </strong><em>new study by Hebrew University is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations, for the first time ever, accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare. This study has unveiled a previously unknown type of shockwave within TDEs, settling a longstanding debate about the energy source of the brightest phases in these events. It confirms that shock dissipation powers the brightest weeks of a TDE flare, opening doors for future studies to utilize TDE observations as a means to measure essential properties of black holes and potentially test Einstein's predictions in extreme gravitational environments.</em></p>
Do you know what happens to a star when it gets gobbled up by a black hole? It was in 2019 when astronomers saw an example of a star that was shredded after it got too close to a massive black hole.
