Torsionally excited methanol in massive young stellar objects: The role of the mid-IR radiation field

Infall and Outflow Towards High-mass Starless Clump Candidates
T. G. S. Pillai, J. S. Urquhart, S. Leurini +6
The evolutionary sequence for high-mass star formation starts with massive starless clumps that go on to form protostellar, young stellar objects and then compact HII regions. Whil…
Kinematics and stability of high-mass protostellar disk candidates at sub-arcsecond resolution -- Insights from the IRAM NOEMA large program CORE
Aida Ahmadi, H. Beuther, F. Bosco +28
The fragmentation mode of high-mass molecular clumps and the accretion processes that form the most massive stars () are still not well understood. To this end,…
