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…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Á. Kóspál, P. Ábrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
ANTIHEROES-PRODIGE: Quantifying the connection from envelope to disk with the IRAM 30m telescope and NOEMA I. Attack of the streamers: L1448N's fight for order in the chaos
C. Gieser, P. Caselli, D. M. Segura-Cox +19
Star formation is a hierarchical process ranging from molecular clouds down to individual protostars. In particular how infalling asymmetric structures, called streamers, deliverin…
Protoplanetary disk masses in NGC 2024: Evidence for two populations
Sierk E. van Terwisga, Ewine F. van Dishoeck, Rita K. Mann +8
Protoplanetary disks in dense, massive star-forming regions are strongly affected by their environment. How this environmental impact changes over time is an important constraint o…
Demographics of disks around young very low-mass stars and brown dwarfs in Lupus
E. Sanchis, L. Testi, A. Natta +15
We present new 890 continuum ALMA observations of 5 brown dwarfs (BDs) with infrared excess in Lupus I and III -- which, in combination with 4 BDs previously observed, allowed…
Bright C2H emission in protoplanetary disks in Lupus: high volatile C/O>1 ratios
A. Miotello, S. Facchini, E. F. van Dishoeck +6
ALMA surveys have shown that CO emission in protoplanetary disks is much fainter than expected. Accordingly, CO-based gas masses and gas/dust ratios are orders of magnitude lower t…
The ALMA Lupus protoplanetary disk survey: evidence for compact gas disks and molecular rings from CN
S. E. van Terwisga, E. F. van Dishoeck, P. Cazzoletti +10
The cyanide radical CN is abundant in protoplanetary disks, with line fluxes often comparable to those of CO. It is known to be sensitive to UV irradiation of the upper disk…
V1094 Sco: a rare giant multi-ringed disk around a T Tauri star
S. E. van Terwisga, E. F. van Dishoeck, M. Ansdell +11
A wide variety of ring-like dust structures has been detected in protoplanetary disks, but their origin and frequency are still unclear. We characterize the structure of an extende…
