Interstellar disparity: N- vs O-bearing molecules: A multidisciplinary perspective across interstellar environments
Mathilde Bouvier, Joan Enrique-Romero, Marta De Simone
Observations of O- and N-bearing molecules reveal systematic chemical differentiation across a wide range of interstellar environments. This pattern is peculiar and its origin like…
FAUST XXIV. Large dust grains in the protostellar outflow cavity walls of the Class I binary L1551 IRS5
G. Sabatini, E. Bianchi, C. J. Chandler +19
Planet formation around young stars requires the growth of interstellar dust grains from mm-sized particles to km-sized planetesimals. Numerical simulations have shown that large (…
FAUST XXV. A potential new molecular outflow in [BHB2007] 11
A. Martínez-Henares, I. Jiménez-Serra, C. Vastel +26
During the early stages of star formation, accretion processes such as infall from the envelope and molecular streamers, and ejection of matter through winds and jets take place si…
Discovery of an intriguing chemically rich outflow in the OMC-2/3 filament
M. Bouvier, L. Giani, L. Chahine +3
Studying chemically rich protostellar outflows and their jet provides an important insight into the low-mass star formation process and its related chemistry. Whilst well-known sho…
FAUST XIX. DCO in the outflow cavities of NGC\,1333 IRAS\,4A: recovering the physical structure of its original prestellar core
Layal Chahine, Cecilia Ceccarelli, Marta De Simone +25
Molecular deuteration is a powerful diagnostic tool for probing the physical conditions and chemical processes in astrophysical environments. In this work, we focus on formaldehyde…
Multiple chemical tracers finally unveil the intricate NGC\,1333 IRAS\,4A outflow system. FAUST XVI
Layal Chahine, Cecilia Ceccarelli, Marta De Simone +54
The exploration of outflows in protobinary systems presents a challenging yet crucial endeavour, offering valuable insights into the dynamic interplay between protostars and their…
FAUST XIII. Dusty cavity and molecular shock driven by IRS7B in the Corona Australis cluster
G. Sabatini, L. Podio, C. Codella +54
The origin of the chemical diversity observed around low-mass protostars probably resides in the earliest history of these systems. We aim to investigate the impact of protostellar…
FAUST X: Formaldehyde in the Protobinary System [BHB2007] 11: Small Scale Deuteration
Lucy Evans, Charlotte Vastel, Francisco Fontani +16
Context. Deuterium in H-bearing species is enhanced during the early stages of star formation, however, only a small number of high spatial resolution deuteration studies exist tow…
Streamers feeding the SVS13-A protobinary system: astrochemistry reveals accretion shocks?
Eleonora Bianchi, Ana López-Sepulcre, Cecilia Ceccarelli +6
We report ALMA high-angular resolution (~ 50 au) observations of the binary system SVS13-A. More specifically, we analyse deuterated water (HDO) and sulfur dioxide (SO2) emission.…
Reconstructing the shock history in the CMZ of NGC 253 with ALCHEMI
K. -Y. Huang, S. Viti, J. Holdship +19
HNCO and SiO are well known shock tracers and have been observed in nearby galaxies, including the nearby (D=3.5 Mpc) starburst galaxy NGC 253. The simultaneous detection of these…
OMC-2 FIR 4 under the microscope: Shocks, filaments, and a highly collimated jet at 100 au scales
L. Chahine, A. López-Sepulcre, L. Podio +14
Star-forming molecular clouds are characterised by the ubiquity of intertwined filaments. The filaments have been observed in both high- and low-mass star-forming regions, and are…
FAUST VI. VLA 1623--2417 B: a new laboratory for astrochemistry around protostars on 50 au scale
C. Codella, A. López-Sepulcre, S. Ohashi +25
The ALMA interferometer, with its unprecedented combination of high-sensitivity and high-angular resolution, allows for (sub-)mm wavelength mapping of protostellar systems at Solar…
Hot methanol in the [BHB2007] 11 protobinary system: hot corino versus shock origin? : FAUST V
C. Vastel, F. Alves, C. Ceccarelli +63
Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the building-up of the chemical complexity in star formi…
