THE SLOW IONIZED WIND AND ROTATING DISKLIKE SYSTEM THAT ARE ASSOCIATED WITH THE HIGH-MASS YOUNG STELLAR OBJECT G345.4938+01.4677 [PDF]
, 2014 We report the detection, made using ALMA, of the 92 GHz continuum and hydrogen recombination lines (HRLs) H40α, H42α, and H50β emission toward the ionized wind associated with the high-mass young stellar object G345.4938+01.4677.

Outbursting Young Stellar Object PGIR 20dci in the Perseus Arm [PDF]
Astronomical Journal, 2021 We report the discovery of a likely outbursting Class I young stellar object, associated with the star-forming region NGC 281-W (distance ∼2.8 kpc). The source is currently seen only at infrared wavelengths, appearing in both the Palomar Gattini InfraRed

Young Stellar Object Candidates in IC 417
The Astronomical Journal, 2023 IC 417 is in the Galactic plane, and likely part of the Aur OB2 association; it is ∼2 kpc away. Stock 8 is one of the densest cluster constituents; off of it to the east, there is a “nebulous stream” (NS) that is dramatic in the infrared (IR).

KFPA Examinations of Young STellar Object Natal Environments (KEYSTONE): Hierarchical Ammonia Structures in Galactic Giant Molecular Clouds [PDF]
Astrophysical Journal, 2019 We present initial results from the K-band Focal Plane Array Examinations of Young STellar Object Natal Environments survey, a large project on the 100 m Green Bank Telescope mapping ammonia emission across 11 giant molecular clouds at distances of 0.9–3.

Radiative Transfer Modeling of EC 53: An Episodically Accreting Class I Young Stellar Object [PDF]
Astrophysical Journal, 2019 In the episodic accretion scenario, a large fraction of the protostellar mass accretes during repeated and large bursts of accretion. Since outbursts on protostars are typically identified at specific wavelengths, interpreting these outbursts requires ...

13CH3OH Masers Associated With a Transient Phenomenon in a High-mass Young Stellar Object
Astrophysical Journal, 2020 We report the first detection of isotopic methanol (13CH3OH) maser emission in interstellar space. The emission was detected toward the high-mass young stellar object G358.93-0.03 during monitoring of a flare in the 6.7 GHz methanol (CH3OH) maser ...

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.
