Cosmic-Ray Diffusion Suppression in Star-forming Regions Inhibits Clump Formation in Gas-rich Galaxies [PDF]
Astrophysical Journal, 2020 Observations of the γ-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy ...

Ionization: a possible explanation for the difference of mean disk sizes in star-forming regions [PDF]
Astronomy & Astrophysics, 2020 Context. Surveys of protoplanetary disks in star-forming regions of similar age revealed significant variations in average disk mass in some regions. For instance, disks in the Orion Nebular Cluster (ONC) and Corona Australis (CrA) are on average smaller

The Star Formation in Radio Survey: 3–33 GHz Imaging of Nearby Galaxy Nuclei and Extranuclear Star-forming Regions [PDF]
Astrophysical Journal Supplement Series, 2020 We present 3, 15, and 33 GHz imaging toward galaxy nuclei and extranuclear star-forming regions using the Karl G. Jansky Very Large Array as part of the Star Formation in Radio Survey.

Survey of ortho-H2D+ in high-mass star-forming regions [PDF]
Astronomy & Astrophysics, 2020 Context. Deuteration has been suggested to be a reliable chemical clock of star-forming regions due to its strong dependence on density and temperature changes during cloud contraction. In particular, the H3+ isotopologues (e.g.

Trigonometric Parallaxes of High-mass Star-forming Regions: Our View of the Milky Way [PDF]
Astrophysical Journal, 2019 We compile and analyze approximately 200 trigonometric parallaxes and proper motions of molecular masers associated with very young high-mass stars. Most of the measurements come from the BeSSeL Survey using the VLBA and the Japanese VERA project.

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).

HH 80/81: Structure and Kinematics of the Fastest Protostellar Outflow
The Astrophysical Journal, 2023 Hubble Space Telescope (HST) images obtained in 2018 are combined with archival HST data taken in 1995 to detect changes and measure proper motions in the HH 80/81 shock complex, which is powered by the fastest known jet driven by a forming star, the ...
