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 …

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 …

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 …

High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of
disk-aided accretion,. Such accretion events are rare and difficult to observe directly but are …

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 …

Context. Accretion bursts from low-mass young stellar objects (YSOs) have been known for
many decades. In recent years, the first accretion bursts of massive YSOs (MYSOs) have …

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 …

Context. The massive young stellar object (MYSO) G358. 93− 0.03-MM1 showed an
extraordinary near-infrared-to (sub-) millimetre-dark and far-infrared-loud accretion burst …

We report the detection of new 12.178, 12.229, 20.347, and 23.121 GHz methanol masers in
the massive star-forming region G358. 93− 0.03, which are flaring on similarly short time …

In 2019 September, a sudden flare of the 6.7 GHz methanol maser was observed toward the
high-mass young stellar object (HMYSO) G24. 33+ 0.14. This may represent the fourth …
