"Monstrous Black Hole Devours Three Earths'-Worth of Stars in Stellar Feast"

Astronomers from the University of Leicester have discovered a star similar to our Sun being incrementally devoured by a small black hole, losing the equivalent mass of three Earths with each close pass. The discovery, made using the Swift satellite, provides a "missing link" in our understanding of black holes disrupting orbiting stars and suggests the existence of undiscovered stars in the process of being consumed. The regularity of the star's emissions falls between two known types of outbursts, indicating a connection between them. The researchers anticipate finding more objects like this in the future.

Infant Super-Jupiter Devoured by Star, Creating Fiery Disc and Solving Solar Flare Mystery

A massive stellar flare from the infant protostar FU Ori, located 1,200 light-years from Earth, may have been caused when a planet ten times the size of Jupiter ventured too close to the growing star and burned up in a superheated soup of material swirling around the star. Some of the remains of the planet were then fed to the star, causing it to significantly increase in brightness. The simulation created by a team at the University of Leicester suggests that most developing planetary systems may flare up in a similar way dozens of times or more while their protoplanetary disk is still present.
