"Violent Eruption on Young Sun-like Star Threatens Exoplanet Development"

Astronomers have observed an extreme eruption from a young star, HD 283572, which became over a hundred times brighter in just a few hours, shedding light on the behavior of young sun-like stars and their impact on developing planets. The eruption, detected using the Submillimeter Array, released an immense amount of energy and poses challenges for the development of exoplanets in its vicinity. Further observations are underway to understand the frequency of such flaring activity and its effects on planetary atmospheres.

Unraveling the Enigma: Unprecedented Stellar Flare Outshines the Sun

Scientists from the University of Leicester have proposed a new explanation for a stellar flare a trillion times more powerful than the largest solar flares. They suggest that a massive young planet, roughly ten times larger than Jupiter, is undergoing extreme evaporation near a protostar. The planet's material is being torn off and flung onto the star, causing it to grow brighter. This discovery could reshape our understanding of star and planet formation, as it implies that protoplanetary discs are violent and chaotic environments where many young planets are burned and consumed by their stars.

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.

"Explaining the Trillion Times Brighter Flare: A Star Devours a Super-Jupiter"

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, resulting in an "extreme evaporation" and burning up in a superheated soup of material swirling around the star. Some of the remains of the planet were then fed to the star. The simulation created by a team at the University of Leicester suggested that most developing planetary systems may flare up in a similar way dozens of times or more while their protoplanetary disk is still present.
