Formation and evolution of disks around young stellar objects
Recent observations have suggested that circumstellar disks may commonly form around
young stellar objects. Although the formation of circumstellar disks can be a natural result of …

A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
High-mass protostars (M⋆> 8 M⊙) are thought to gain the majority of their mass via short,
intense bursts of growth. This episodic accretion is thought to be facilitated by gravitationally …

Infrared observations of the flaring maser source G358. 93− 0.03-SOFIA confirms an accretion burst from a massive young stellar object
B Stecklum, V Wolf, H Linz, AC o Garatti… - Astronomy & …, 2021 - aanda.org
Context. Class II methanol masers are signposts of massive young stellar objects (MYSOs).
Recent evidence shows that flares of these masers are driven by MYSO accretion bursts …

Identification of the simplest sugar-like molecule glycolaldehyde towards the hot molecular core G358. 93–0.03 MM1
Glycolaldehyde (CH2OHCHO) is the simplest monosaccharide sugar in the interstellar
medium, and it is directly involved in the origin of life via the 'RNA world'hypothesis. We …

Episodic accretion and mergers during growth of massive protostars
ABSTRACT 3D simulations of high mass young stellar object (HMYSO) growth show that
their circumstellar discs fragment on to multiple self-gravitating objects. Accretion of these by …
