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.…
The accretion burst of the massive young stellar object G323.46 -0.08
V. Wolf, B. Stecklum, A. Caratti o Garatti +10
Accretion bursts from low-mass young stellar objects (YSOs) are known for many decades. In recent years, the first accretion bursts of massive YSOs (MYSOs) have been observed. Thes…
Importance of source structure on complex organics emission. I. Observations of CHOH from low-mass to high-mass protostars
M. L. van Gelder, P. Nazari, B. Tabone +9
Complex organic molecules (COMs) are often observed toward embedded Class 0 and I protostars. However, not all Class 0 and I protostars exhibit COMs emission. In this work, variati…
Gravity and rotation drag the magnetic field in high-mass star formation
H. Beuther, J. D. Soler, H. Linz +8
The formation of hot stars out of the cold interstellar medium lies at the heart of astrophysical research. Understanding the importance of magnetic fields during star formation re…
Spiral arms and instability within the AFGL 4176 mm1 disc
K. G. Johnston, M. G. Hoare, H. Beuther +7
We present high-resolution (30 mas or 130 au at 4.2 kpc) Atacama Large Millimeter/submillimeter Array observations at 1.2 mm of the disc around the forming O-type star AFGL 4176 mm…
Chemical complexity in high-mass star formation: An observational and modeling case study of the AFGL 2591 VLA 3 hot core
C. Gieser, D. Semenov, H. Beuther +30
We present a detailed observational and modeling study of the hot core VLA 3 in the high-mass star-forming region AFGL 2591, which is a target region of the NOrthern Extended Milli…
Fragmentation, rotation and outflows in the high-mass star-forming region IRAS 23033+5951. A case study of the IRAM NOEMA large program CORE
F. Bosco, H. Beuther, A. Ahmadi +23
The formation process of high-mass stars (>8M) is poorly constrained, particularly, the effects of clump fragmentation creating multiple systems and the mechanism of mass a…
Substructures in the Keplerian disc around the O-type (proto)star G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +20
We present the highest angular resolution (20x15mas - 44x33au) Atacama Large Millimeter/sub-millimeter Array (ALMA) observations currently possible of the proto-O-star G17.64+0.16…
IRAS23385+6053: An embedded massive cluster in the making
R. Cesaroni, H. Beuther, A. Ahmadi +26
This study is part of the project ``CORE'', an IRAM/NOEMA large program consisting of observations of the millimeter continuum and molecular line emission towards 20 selected high-…
High-mass star formation at sub-50AU scales
H. Beuther, A. Ahmadi. J. C. Mottram, H. Linz +6
Methods: We observed the high-mass hot core region G351.77-0.54 with ALMA and more than 16km baselines. Results: At a spatial resolution of 18/40au (depending on the distance), we…
Chasing discs around O-type (proto)stars - ALMA evidence for an SiO disc and disc wind from G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +28
We present high angular resolution 0.2 arcsec continuum and molecular emission line Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of G17.64+0.16 in Band 6 (220G…
A New Look at an Old Cluster: The Membership, Rotation, and Magnetic Activity of Low-Mass Stars in the 1.3-Gyr-Old Open Cluster NGC 752
Marcel Agüeros, Emily Bowsher, John Bochanski +8
The nearby open cluster NGC 752 presents a rare opportunity to study stellar properties at ages >1 Gyr. However, constructing a membership catalog for it is challenging; most surve…
Accelerating infall and rotational spin-up in the hot molecular core G31.41+0.31
M. T. Beltrán, R. Cesaroni, V. M. Rivilla +20
As part of our effort to search for circumstellar disks around high-mass stellar objects, we observed the well-known core G31.41+0.31 with ALMA at 1.4 mm with an angular resolution…
Why are rapidly rotating M dwarfs in the Pleiades so (infra)red? New period measurements confirm rotation-dependent color offsets from the cluster sequence
Kevin R. Covey, Marcel A. Agüeros, Nicholas M. Law +6
Stellar rotation periods measured in open clusters have proved to be extremely useful for studying stars' angular momentum content and rotationally driven magnetic activity, which…
