Small and Large Dust Cavities in Disks around mid-M Stars in Taurus
Yangfan Shi, Feng Long, Gregory J. Herczeg +10
High-angular resolution imaging by ALMA has revealed the near-universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence st…
Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?
Daniel Harsono, Feng Long, Paola Pinilla +9
While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This…
JWST Edge-on Disk Ice (JEDIce): Program overview and ice survey results
Jennifer B. Bergner, Nicole Arulanantham, Emmanuel Dartois +21
The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28m spectra of five disk…
A high HDO/HO ratio in the Class I protostar L1551 IRS5
Audrey Andreu, Audrey Coutens, Fernando Cruz-Sáenz de Miera +4
Water is a very abundant molecule in star-forming regions. Its deuterium fractionation is an important tool for understanding its formation and evolution during the star and planet…
JOYS: Launching and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST/MIRI
Åukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +24
Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…
Imaging the water snowline around protostars with water and HCO isotopologues
Merel L. R. van 't Hoff, Daniel Harsono, Martijn L. van Gelder +7
The water snowline location in protostellar envelopes provides crucial information about the thermal structure and the mass accretion process as it can inform about the occurrence…
