PRODIGE -- envelope to disk with NOEMA. IV. An infalling gas bridge surrounding two Class 0/I systems in L1448N
C. Gieser, J. E. Pineda, D. M. Segura-Cox +13
Context. The formation of stars has been subject to extensive studies in the past decades from molecular cloud to protoplanetary disk scales. It is still not fully understood how t…
JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars
M. L. van Gelder, L. Francis, E. F. van Dishoeck +17
The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
JWST Observations of Young protoStars (JOYS). HH 211: the textbook case of a protostellar jet and outflow
A. Caratti o Garatti, T. P. Ray, P. J. Kavanagh +22
We use the James Webb Space Telescope (JWST) and its Mid-Infrared Instrument (MIRI) (5-28 um), to study the embedded HH 211 flow. We map a 0.95'x0.22' region, covering the full ext…
Probing the Physics of Star-Formation (ProPStar) III. No evidence for dissipation of turbulence down to 20 mpc (4 000 au) scale
Jaime E. Pineda, Juan D. Soler, Stella Offner +14
Context. Turbulence is a key component of molecular cloud structure. It is usually described by a cascade of energy down to the dissipation scale. The power spectrum for subsonic i…
Dynamical Accretion Flows -- ALMAGAL: Flows along filamentary structures in high-mass star-forming clusters
M. R. A. Wells, H. Beuther, S. Molinari +47
We use data from the ALMA Evolutionary Study of High Mass Protocluster Formation in the Galaxy (ALMAGAL) survey to study 100 ALMAGAL regions at 1 arsecond resolution located…
JOYS+: link between ice and gas of complex organic molecules. Comparing JWST and ALMA data of two low-mass protostars
Y. Chen, W. R. M. Rocha, E. F. van Dishoeck +16
A rich inventory of complex organic molecules (COMs) has been observed in high abundances in the gas phase toward Class 0 protostars. These molecules are suggested to be formed in…
The Cygnus Allscale Survey of Chemistry and Dynamical Environments: CASCADE III. The large scale distribution of DCO+, DNC and DCN in the DR21 filament
I. Barlach Christensen, F. Wyrowski, V. S. Veena +12
Deuterated molecules and their molecular D/H-ratios (RD(D)) are important diagnostic tools to study the physical conditions of star-forming regions. The degree of deuteration, RD(D…
PRODIGE -- Envelope to Disk with NOEMA III. The origin of complex organic molecule emission in SVS13A
T. -H. Hsieh, J. E. Pineda, D. M. Segura-Cox +18
Complex Organic Molecules (COMs) have been found toward low-mass protostars but the origins of the COM emission are still unclear. It can be associated with, for example, hot corin…
ALMA Observations of Molecular Line Emission from High-excitation Bipolar Planetary Nebulae
Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +7
We present early results from our program of ALMA Band 6 (1.3mm) molecular line mapping of a sample of nearby, well-studied examples of high-excitation, bipolar/pinched-waist and m…
PRODIGE -- Planet-forming disks in Taurus with NOEMA. I. Overview and first results for 12CO, 13CO, and C18O
D. Semenov, Th. Henning, S. Guilloteau +21
We are performing a line survey of 8 planet-forming Class II disks in Taurus with the IRAM NOrthern Extended Millimeter Array (NOEMA), as a part of the MPG-IRAM Observatory Program…
JWST Observations of Young protoStars (JOYS): Linked accretion and ejection in a Class I protobinary system
Łukasz Tychoniec, Martijn L. van Gelder, Ewine F. van Dishoeck +19
Accretion and ejection sets the outcome of the star and planet formation process. The mid-infrared wavelength range offers key tracers of those processes that were difficult to det…
JOYS: MIRI/MRS spectroscopy of gas-phase molecules from the high-mass star-forming region IRAS 23385+6053
L. Francis, M. L. van Gelder, E. F. van Dishoeck +16
Space-based mid-IR spectroscopy provides tracers of warm gas in star-forming regions that are inaccessible from the ground. Past mid-IR spectra of bright high-mass protostars in th…
