Stellar winds of O-type stars traced by high ionization fine-structure emission lines with JWST/MIRI
JWST/MIRI detects [Ne V] 14.3 micron emission from O-star winds in 5 of 22 observed stars, enabling wind speed and mass-loss rate estimates even in weak-wind regimes.

Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys
ALMA comparison finds starless cores in evolved IRBCs have ~2x higher median mass and density than in early IRDCs, favoring competitive accretion over massive prestellar core models for high-mass star formation.

Automated void identification by Blendmask: from hierarchical molecular gas to hierarchical voids in NGC 628
Deep learning identifies voids in NGC 628 with low association to known star clusters, supporting an evolutionary sequence from molecular clouds via stellar feedback to detached voids.

The Sun's chemical peculiarity: disentangling Galactic chemical evolution and planetary engulfment in solar twins
Reanalysis of 79 solar twins indicates the Sun's chemical peculiarity is largely explained by Galactic chemical evolution, with 2-6 candidates possibly showing planetary engulfment.

From filaments to clumps: filament properties with synthetic Herschel observations
Synthetic Herschel observations from simulations yield 8832 filaments hosting 94% of clumps, with power-law mass and length distributions and a density relation qualitatively matching the Hi-GAL survey.

Star Formation at the Periphery of a Molecular Superbubble: The Case of G12.79+0.43
Observational study of G12.79+0.43 identifies YSOs and HII regions powered by B-type stars and associates the complex with the rim of a molecular superbubble of diameter ~50 pc and expansion age ~0.3 Myr without estab...
