PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
MarÃa 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…

Variability of the DG Tau Forbidden Emission Line Low Velocity Component
Noah Otten, Emma Whelan, Yu-Ru Chou +3
Optical Forbidden Emission Lines (FELs) come from transitions with long radiative decay times needing low density gas where collisions between atoms are rare. They are produced in…

A Spectroastrometric Study of the Low-velocity Wind from DG Tau A
Yu-Ru Chou, Michihiro Takami, Shin-Ping Lai +9
We obtained high spectral resolution spectra ( 2.5 km s) for DG Tau A from 4800 Ã to 7500 Ã using Subaru High Dispersion Spectrograph (HDS) for the first time. T…
