On the duration of the embedded phase of star formation

Jaeyeon Kim, Mélanie Chevance, J. M. Diederik Kruijssen +23

Feedback from massive stars plays a key role in molecular cloud evolution. After the onset of star formation, the young stellar population is exposed by photoionization, winds, sup…

ALMA Resolves Giant Molecular Clouds in a Tidal Dwarf Galaxy

M. Querejeta, F. Lelli, E. Schinnerer +12

Tidal dwarf galaxies (TDGs) are gravitationally bound condensations of gas and stars formed during galaxy interactions. Here we present multi-configuration ALMA observations of J10…

Resolving the Dust-to-Metals Ratio and CO-to-H Conversion Factor in the Nearby Universe

I-Da Chiang, Karin M. Sandstrom, Jérémy Chastenet +8

We investigate the relationship between the dust-to-metals ratio (D/M) and the local interstellar medium environment at ~2 kpc resolution in five nearby galaxies: IC342, M31, M33,…

Black hole feeding and star formation in NGC 1808

A. Audibert, F. Combes, S. García-Burillo +11

We report on Atacama Large Millimeter Array (ALMA) observations of CO(3-2) emission in the Seyfert2/starburst galaxy NGC1808, at a spatial resolution of 4pc. Our aim is to investig…

Pre-supernova feedback mechanisms drive the destruction of molecular clouds in nearby star-forming disc galaxies

Mélanie Chevance, J. M. Diederik Kruijssen, Mark R. Krumholz +28

It is a major open question which physical processes stop the accretion of gas onto giant molecular clouds (GMCs) and limit the efficiency at which gas is converted into stars with…

On the Nature of the T Tauri Triple System

Tracy L. Beck, G. H. Schaefer, S. Guilloteau +4

We present a multi-wavelength analysis to reveal the nature of the enigmatic T Tauri triple star system. New optical and infrared measurements are coupled with archival X-ray, UV a…

Quantitative inference of the column densities from 3 mm molecular emission: A case study towards Orion B

Pierre Gratier, Jérôme Pety, Emeric Bron +21

Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or…

Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids

Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21

The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…

Ubiquitous velocity fluctuations throughout the molecular interstellar medium

J. D. Henshaw, J. M. D. Kruijssen, S. N. Longmore +23

The density structure of the interstellar medium (ISM) determines where stars form and release energy, momentum, and heavy elements, driving galaxy evolution. Density variations ar…

A 3mm chemical exploration of small organics in Class I YSOs

Romane Le Gal, Karin I. Öberg, Jane Huang +8

There is mounting evidence that the composition and structure of planetary systems are intimately linked to their birth environments. During the past decade, several spectral surve…

An attempt to detect transient changes in Io's SO2 and NaCl atmosphere

L. Roth, J. Boissier, A. Moullet +15

Io's atmosphere is predominately SO2 sustained by a combination of volcanic outgassing and sublimation. The loss from the atmosphere is the main mass source for Jupiter's large mag…

A Study of Millimeter Variability in FUor Objects

John Wendeborn, Catherine C. Espaillat, Enrique Macias +6

FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption,…

Possible evidence of ongoing planet formation in AB Aurigae. A showcase of the SPHERE/ALMA synergy

A. Boccaletti, E. Di Folco, E. Pantin +8

Context. Planet formation is expected to take place in the first million years of a planetary system through various processes, which remain to be tested through observations. Aims…

Unusually High CO Abundance of the First Active Interstellar Comet

M. A. Cordiner, S. N. Milam, N. Biver +12

Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary observations can therefore pr…

Constraining MHD disk winds with ALMA. Apparent rotation signatures and application to HH212

B. Tabone, S. Cabrit, G. Pineau des Forêts +7

Large millimeter interferometers are revealing a growing number of rotating outflows, which are suggested to trace magneto-centrifugal disk winds (MHD DWs). However, their impact o…
