The burst mode of accretion in massive star formation

Abstract: The burst mode of accretion in star formation is a paradigm that describes how stars acquire their mass during the birth of young stellar objects. One particular scenario proposes that the stars grow in mass via episodic accretion of fragments migrating from their gravitationally unstable circumstellar discs and it naturally explains the existence of observed pre-main sequence bursts from high-mass protostars. We will review the foundations of the burst mode of accretion is star formation, explicit the differences/similitudes between low-mass and high-mass star formation in the context of recent observations.
