OGHReS: Star formation in the Outer Galaxy II (-)
J. S. Urquhart, C. Koenig, D. Colombo +19
The Outer Galaxy High-Resolution Survey (OGHReS) covers 100 square degrees () in the (2--1) transitions of three CO-isotopologues. We use the spectra…
CHOH as a User-Friendly Density Probe: Calibration and Beyond
A. Giannetti, S. Leurini, E. Schisano +4
Almost all the physics of star formation critically depends on the number density of the molecular gas. However, the methods to estimate this key property often rely on uncertain a…
Gas infall via accretion disk feeding Cepheus A HW2
A. Sanna, A. Oliva, L. Moscadelli +10
The star-forming region Cepheus A hosts a very young star, called HW2, that is the second closest to us growing a dozen times more massive than our Sun. The circumstellar environme…
Time evolution of o-HD, ND, and NH during the high-mass star formation process
G. Sabatini, S. Bovino, E. Redaelli +5
Deuterium fractionation is a well-established evolutionary tracer in low-mass star formation, but its applicability to the high-mass regime remains an open question. The abundances…
