![]() One of the strange things about this transient is that it doesn’t seem to be associated with a particular galaxy. Based on observations of ZTF20abrbeie, it was likely a TDE involving a 14 solar mass star and a supermassive black hole more massive than 100 million Suns. ![]() The superheated material of the star is captured by the black hole. ![]() They first rip the star apart in what is known as a tidal disruption event (TDE). It’s hard to imagine the scale of this transient.Īccording to a study being published in The Astrophysical Journal Letters there’s really only one phenomenon that could explain Scary Barbie: A star being consumed by a black hole. A supernova can outshine a galaxy, but Scary Barbie is a thousand times more energetic than the brightest supernovae. The second is how terrifyingly energetic it is. The afterglow of a supernova can be observed for a month, but Scary Barbie has lasted for more than 800 days and continues to be visible. The first is that it has lasted much longer than typical transients. It’s an unusual transient for two reasons. Scary Barbie was first observed in 2020 and was later observed over a range of wavelengths. Take for example the transient known as ZTF20abrbeie, nicknamed Scary Barbie. Transients are quite common, but some of them can challenge explanations. These short-lived cosmic events are known as transients and include things such as supernovae and gamma-ray bursts. The event then fades into the darkness and the cosmos returns to normal. A cataclysmic event occurs in the universe and releases a tremendous amount of energy in a short period of time.
