Resumen de Rare glimpse at a black hole devouring a star
We have spotted what seems to be a star being torn up and eaten by a black hole more than 1 billion light years away. A team of astronomers led by Ben Shappee at the University of Hawaii thinks it has seen the aftermath of this process. The group reported four sets of telescope observations on Mar 24 on the Astronomer's Telegram website, where people post observations of cosmic phenomena. At first glance, a star being shredded resembles a supernova, because both generate sudden, bright bursts of light. So, when researchers spot a potential tidal disruption event they coiled as much data as possible to try to tell the difference. A few factors indicate that this signal might be tidal disruption. It seems to be in the center of its galaxy, a requirement for a tidal disruption event but not for a supernova. Its light is very blue, meaning it is extremely hot whereas supernovae tend to cool as they expand. It also shows no sign of the heavy elements that absorb some light from a supernova.
