The Relative Cold-trapping Likelihood of Water on Airless Rocky Bodies

The Planetary Science Journal
Many planetoids are airless, but despite the lack of a collisional atmosphere, these bodies can experience volatile migration toward the polar regions via the exosphere.

Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51

The Astrophysical Journal Letters
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar medium (ISM). JWST spectra of four star-forming regions in M51 show an emission

Gas-Phase Infrared Action Spectroscopy of CH₂Cl⁺ and CH₃ClH⁺: Likely Protagonists in Chlorine Astrochemistry

Molecules
Two fundamental halocarbon ions, CH2Cl+ and CH3ClH+, were studied in the gas phase using the FELion 22-pole ion trap apparatus and the Free Electron Laser for Infrared eXperiments (FELIX) at Radboud University, Nijmegen (the Netherlands). The vibrational

FEAST: A NIRSpec/MOS Survey of Emerging Young Star Clusters in NGC 628

The Astrophysical Journal
JWST can pierce through dusty molecular clouds to study the early stages of star formation, where young star clusters are actively driving stellar feedback and still emerging from their natal cloud.

The Milky Way Project: Bridging Intermediate- and High-mass Star Formation with the MIRION Catalog of Yellowballs

The Astrophysical Journal
We describe the construction and use of the Mid-InfraRed Interstellar Objects and Nebulae (MIRION) catalog, which was compiled from 6176 objects identified as “yellowballs” (YBs) by participants in the Milky Way Project.
