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…
Large Myr-old Disks are Not Severely Depleted of gas-phase CO or carbon
Ilaria Pascucci, Bennett N. Skinner, Dingshan Deng +6
We present an ACA search for [CI] emission at 492GHz toward large T Tauri disks (gas radii au) in the Myr-old Lupus star-forming region. Combined with ALMA 1…
An unbiased NOEMA 2.6 to 4 mm survey of the GG Tau ring: First detection of CCS in a protoplanetary disk
N. T. Phuong, A. Dutrey, E. Chapillon +13
Molecular line surveys are among the main tools to probe the structure and physical conditions in protoplanetary disks (PPDs), the birthplace of planets. The large radial and verti…
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…
GG Tau A: gas properties and dynamics from the cavity to the outer disk
N. T. Phuong, A. Dutrey, P. N. Diep +13
We used new ALMA CO and CO(3-2) observations obtained at high angular resolution (0.2") together with previous CO(3-2) and (6-5) ALMA data and continuum maps at…
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…
