The CepA disk-outflow system at <=0.2'' or <=100au resolution
H. Beuther, C. Gieser, V. Aberham +21
Context: Although there has been significant progress, the physical properties and potential fragmentation of accretion disks around high-mass protostars remain poorly constrained.…
Protostellar Outflows at the EarliesT Stages (POETS). IX. Magnetohydrodynamic disk winds traced by SO and SO in luminous protostars
L. Moscadelli, H. Beuther, A. Sanna +13
We investigate two massive young stellar objects (YSOs), IRAS21078+5211 and G035.02+0.35, where evidence for magnetohydrodynamic (MHD) disk winds (DWs) has been obtained at scales…
Filamentary accretion flows in high-mass star-forming clouds
J. -E. Schneider, H. Beuther, C. Gieser +11
We quantify the gas flows from a scale of up to several parsecs down to the sub-parsec scale along filamentary structures in the three high-mass star-forming regions G75.78, IRAS21…
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…
