Disk-mediated accretion burst in a high-mass young stellar object [PDF]
Nature Physics, 2016 Observations show that, like light solar-mass stars, heavy stars also form through episodic disk-accretion; but faster, more energetic and emitting more light. Solar-mass stars form via disk-mediated accretion.

IRAS 19520+2759: a 105 L⊙ massive young stellar object driving a collimated outflow [PDF]
, 2012 The theory of massive star formation currently suffers from a scarce observational base of massive young stellar objects to compare with. In this paper, we present interferometric 12 CO(1–0), 13 CO(1–0), C 18 O(1–0), and 2.6 mm continuum images of the ...

The peculiar dipping events in the disc-bearing young-stellar object EPIC 204278916 [PDF]
, 2016 EPIC 204278916 has been serendipitously discovered from its K2 light curve that displays irregular dimmings of up to 65 per cent for ≈25 consecutive days out of 78.8 d of observations.

Accelerating a water maser face-on jet from a high mass young stellar object [PDF]
, 2015 We report on a long-term single-dish and VLBI monitoring for intermittent flare activities of a Dominant Blue-Shifted H$_{2}$O Maser (DBSM) associated with a southern high mass young stellar object, G353.273+0.641.

SPECTROSCOPIC ASSESSMENT OF WISE-BASED YOUNG STELLAR OBJECT SELECTION NEAR λ AND σ ORIONIS [PDF]
, 2015 We have conducted a sensitive search down to the hydrogen burning limit for unextincted stars over ∼200 square degrees around Lambda Orionis and 20 square degrees around Sigma Orionis using the methodology of Koenig & Leisawitz.

Origin of Interstellar Object A/2017 U1 in a Nearby Young Stellar Association? [PDF]
, 2017 We suggest that the kinematics and properties of interstellar object A/2017 U1 point towards its formation in a protoplanetary disk in the ~45 Myr-old Carina or Columba young stellar associations, and subsequent ejection with a low peculiar velocity (1-2
