Exploring the formation pathways of formamide near young O-type stars

Veronica Allen, Floris F. S. van der Tak, Ana López-Sepulcre +4

Context. As a building block for amino acids, formamide (NH $_{2}$ CHO) is an important molecule in astrobiology and astrochemistry, but its formation path in the interstellar medium i…

Multiple nitrogen reservoirs in a protoplanetary disk at the epoch of comet and giant planet formation

Pierre Hily-Blant, Victor Magalhaes de Souza, Joel Kastner +1

The isotopic ratio of nitrogen measured in primitive Solar System bodies shows a broad range of values, the origin of which remains unknown. One key question is whether these isoto…

Molecular outflows in local galaxies: Method comparison and a role of intermittent AGN driving

D. Lutz, E. Sturm, A. Janssen +17

We report new detections and limits from a NOEMA and ALMA CO(1-0) search for molecular outflows in 13 local galaxies with high FIR surface brightness, and combine with results from…

The lifecycle of molecular clouds in nearby star-forming disc galaxies

Mélanie Chevance, J. M. Diederik Kruijssen, Alexander P. S. Hygate +29

It remains a major challenge to derive a theory of cloud-scale ( $≲ 100$ pc) star formation and feedback, describing how galaxies convert gas into stars as a function of the g…

The Gas-Star Formation Cycle in Nearby Star-Forming Galaxies I. Assessment of Multi-scale Variations

Eva Schinnerer, Annie Hughes, Adam Leroy +21

The processes regulating star formation in galaxies are thought to act across a hierarchy of spatial scales. To connect extragalactic star formation relations from global and kpc-s…

Mapping metallicity variations across nearby galaxy disks

K. Kreckel, I. -T. Ho, G. A. Blanc +21

The distribution of metals within a galaxy traces the baryon cycle and the buildup of galactic disks, but the detailed gas phase metallicity distribution remains poorly sampled. We…

The HH 212 interstellar laboratory: astrochemistry as a tool to reveal protostellar disks on Solar System scales around a rising Sun

Claudio Codella, Cecilia Ceccarelli, Chin-Fei Lee +8

The investigation of star forming regions have enormously benefited from the recent advent of the ALMA interferometer. More specifically, the unprecedented combination of high-sens…

Masses and Implications for Ages of Low-Mass Pre-Main Sequence Stars in Taurus and Ophiuchus

M. Simon, S. Guilloteau, Tracy L. Beck +6

The accuracy of masses of pre-main sequence (PMS) stars derived from their locations on the Hertzsprung-Russell Diagram (HRD) can be tested by comparison with accurate and precise…

On the perimeter length determination of the eight-centered oval

Jean-Marc Ginoux, Jean-Claude Golvin

On the perimeter length determination of the eight-centered oval. Several studies have shown that an eight-centered oval coincides almost perfectly with the ellipse constructed on…

EMPIRE: The IRAM 30-m Dense Gas Survey of Nearby Galaxies

María J. Jiménez-Donaire, F. Bigiel, A. K. Leroy +14

We present EMPIRE, an IRAM 30-m large program that mapped $λ = 3 - 4$ mm dense gas tracers at $\sim 1 - 2$ kpc resolution across the whole star-forming disk of nine nearby, massive…

APEX Observations of the CO Envelope around the Young FUor-type Star V883 Ori

Jacob Aaron White, Á. Kóspál, C. Rab +9

The accretion-driven outbursts of young FU Orionis-type stars may be a common stage of pre-main sequence evolution and can have a significant impact on the circumstellar environmen…

Observation of narrow polar jets in the nascent wind of oxygen-rich AGB star EP Aqr

P. Tuan-Anh, D. T. Hoai, P. T. Nhung +6

Using ALMA observations of $^{12}$ CO(2-1), $^{28}$ SiO(5-4) and $^{32}$ SO $_{2}$ (16 $_{6, 10}$ -17 $_{5, 13}$ ) emissions of the circumstellar envelope of AGB star EP Aqr, we describe the mo…

A dynamically young, gravitationally stable network of filaments in Orion B

Jan H. Orkisz, Nicolas Peretto, Jérôme Pety +15

Filaments are a key step on the path that leads from molecular clouds to star formation. However, their characteristics are heavily debated, and the exact processes that lead to th…

Dense gas is not enough: environmental variations in the star formation efficiency of dense molecular gas at 100pc scales in M51

M. Querejeta, E. Schinnerer, A. Schruba +17

It remains unclear what sets the efficiency with which molecular gas transforms into stars. Here we present a new VLA map of the spiral galaxy M51 in 33GHz radio continuum, an exti…

PHIBSS2: survey design and z=0.5-0.8 results. Molecular gas reservoirs during the winding-down of star formation

J. Freundlich, F. Combes, L. J. Tacconi +29

Following the success of the Plateau de Bure high-z Blue Sequence Survey (PHIBSS), we present the PHIBSS2 legacy program, a survey of the molecular gas properties of star-forming g…

Disruption of the Orion Molecular Core 1 by the stellar wind of the massive star $θ^{1}$ Ori C

C. Pabst, R. Higgins, J. R. Goicoechea +10

Massive stars inject mechanical and radiative energy into the surrounding environment, which stirs it up, heats the gas, produces cloud and intercloud phases in the interstellar me…
