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…
Core fragmentation and Toomre stability analysis of W3(H2O): A case study of the IRAM NOEMA large program CORE
A. Ahmadi, H. Beuther, J. C. Mottram +30
The fragmentation mode of high-mass molecular clumps and the properties of the central rotating structures surrounding the most luminous objects have yet to be comprehensively char…
Fragmentation and disk formation during high-mass star formation: The IRAM NOEMA (Northern Extended Millimeter Array) large program CORE
H. Beuther, J. C. Mottram, A. Ahmadi +30
Aims: We aim to understand the fragmentation as well as the disk formation, outflow generation and chemical processes during high-mass star formation on spatial scales of individua…
Multi-directional mass-accretion and collimated outflows in W51
Ciriaco Goddi, Adam Ginsburg, Luke Maud +2
We observed the W51 high-mass star-forming complex with ALMA's longest-baseline configurations, achieving an angular resolution of 20 milliarcseconds, corresponding to a line…
Radiative transfer modelling of W33A MM1: 3-D structure and dynamics of a complex massive star forming region
Andrés F. Izquierdo, Roberto Galván-Madrid, Luke T. Maud +5
We present a composite model and radiative transfer simulations of the massive star forming core W33A MM1. The model was tailored to reproduce the complex features observed with AL…
