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 …

Observed changes in protostellar brightness can be complicated to interpret. In our James
Clerk Maxwell Telescope (JCMT) Transient Monitoring Survey, we discovered that a young …

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 …

Context. Growing observational evidence indicates that the accretion process leading to star
formation may occur in an episodic way, through accretion outbursts revealed in various …

Evidence of efficient acceleration of cosmic rays in massive young stellar objects has been
recently reported. Among these massive protostars, S255 NIRS 3, for which extreme flaring …

Context. Maser flares are particularly significant in the study of massive star formation as
they not only signal but also provide unique insights into transient phenomena such as …

We report the detection of the millimeter CH 3 OH masers including a new detection of class
I (11 0, 11–10 1, 10 A) and class II (6 1, 5–5 2, 4 E) maser transitions toward the high-mass …

Context. High-mass young stellar objects gain most of their mass in short intense bursts of
accretion. Maser emission is an invaluable tool in discovering and probing these accretion …

Aims. We present observations of the high-mass star-forming region S255IR, which harbors
the~ 20 M⊙ protostar NIRS3, where a disk-mediated accretion burst was recorded several …

The high-mass young stellar object G358. 93-0.03-MM1 underwent a rapid accretion burst
event from 2019 January to June, resulting in flares observed in most class II methanol …
