This process is known as mass accretion from the circumstellar disc of the star.\u00a0<\/span><\/p>\n On occasions their feeding rate increases. This is known as the periods of enhanced mass accretion from their circumstellar disc. During such episodes, the brightness of the star increases by 4-6 magnitudes in the optical bands.\u00a0<\/span><\/p>\n So far 25 such rare groups of stars have been discovered.<\/span><\/p>\n Significance of this discovery: <\/b>This discovery could help probe into this group of <\/span>Episodic Accreting young stars <\/span>and their formation mechanism in greater detail.\u00a0<\/span><\/p>\n Source: <\/b>This post is based on the article <\/span>\u201c<\/b>A newly discovered episodically accreting young star could help probe this rare group in more details<\/b>\u201d <\/b>published in<\/span> PIB <\/b>on<\/span> 25th April 2022.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":" What is the News?
