Preferential alignment of Class 0, Class I protostellar disks in multiple systems across nine nearby molecular clouds

Cheng-Han Hsieh, Aleksey Generozov, Stella S. R. Offner +6

The study examines the orientations of protostellar disks in 512 Class 0, Class I, and flat‑spectrum sources across nine nearby molecular clouds, finding that disks in binary and h…

Ice Deposition Fronts In Porous Bodies From Transient Heating Events In a Protoplanetary Disk

Stephen Li, Alice C. Quillen, Adam E. Rubinstein +2

The paper models how transient heating events in a protoplanetary disk cause volatile gases to diffuse into porous bodies and form moving ice deposition fronts, altering the subsur…

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…

CAMPOS II. The onset of protostellar disk substructures and planet formation

Cheng-Han Hsieh, Héctor G. Arce, María José Maureira +6

The 1.3 mm CAMPOS survey has resolved 90 protostellar disks with ~15 au resolution across the Ophiuchus, Corona Australis, and Chamaeleon star-forming regions. To address the funda…

Mapping the merging zone of late infall in the AB Aur planet-forming system

Jessica Speedie, Ruobing Dong, Richard Teague +10

Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…

Resolved Gas Temperatures and 12C/13C ratios in SVS13A from ALMA Observations of CH3CN and CH3-13-CN

T. -H. Hsieh, J. E. Pineda, D. M. Segura-Cox +11

Context. Multiple systems are common in field stars, and the frequency is found to be higher in early evolutionary stages. Thus, the study of young multiple systems during the embe…
