PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
María Teresa Valdivia-Mena, Jaime E. Pineda, Caroline Gieser +24
(Abridged) Recently, streamers have been observed causing shocks at the outer edge of protoplanetary disks. The study of sulfur-bearing species can help us to understand the physic…
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…
Probing the Physics of Star-Formation (ProPStar): II. The first systematic search for streamers toward protostars
María Teresa Valdivia-Mena, Jaime E. Pineda, Paola Caselli +9
The detection of narrow channels of accretion toward protostellar disks, known as streamers, have increased in number in the last few years. However, it is unclear if streamers are…
Anatomy of the Class I protostar L1489 IRS with NOEMA -- I. Disk, streamers, outflow(s) and bubbles at 3mm
M. Tanious, R. Le Gal, R. Neri +7
Over the past few years, chemical studies have revealed multiple structures in the vicinity of young stellar objects (YSOs). It has become evident that specific physical conditions…
