The edge-on disk Tau042021: icy grains at high altitudes and a wind containing astronomical PAHs
E. Dartois, J. A. Noble, M. K. McClure +9
Spectra of the nearly edge-on protoplanetary disks observed with the JWST have shown ice absorption bands of varying optical depths and peculiar profiles, challenging radiative tra…
Ice inventory towards the protostar Ced 110 IRS4 observed with the James Webb Space Telescope. Results from the ERS Ice Age program
W. R. M. Rocha, M. K. McClure, J. A. Sturm +37
This work focuses on the ice features toward the binary protostellar system Ced 110 IRS 4A and 4B, and observed with JWST as part of the Early Release Science Ice Age collaboration…
JWST ice band profiles reveal mixed ice compositions in the HH 48 NE disk
Jennifer B. Bergner, J. A. Sturm, Elettra L. Piacentino +19
Planet formation is strongly influenced by the composition and distribution of volatiles within protoplanetary disks. With JWST, it is now possible to obtain direct observational c…
A JWST/MIRI analysis of the ice distribution and PAH emission in the protoplanetary disk HH 48 NE
J. A. Sturm, M. K. McClure, D. Harsono +18
Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. How…
Constraints on the gas-phase C/O ratio of DR Tau's outer disk from CS, SO, and CH observations
Jane Huang, Edwin A. Bergin, Romane Le Gal +4
Millimeter wavelength observations of Class II protoplanetary disks often display strong emission from hydrocarbons and high CS/SO values, providing evidence that the gas-phase C/O…
JWST MIRI MRS Images Disk Winds, Water, and CO in an Edge-On Protoplanetary Disk
Nicole Arulanantham, M. K. McClure, Klaus Pontoppidan +14
We present JWST MIRI MRS observations of the edge-on protoplanetary disk around the young sub-solar mass star Tau 042021, acquired as part of the Cycle 1 GO program "Mapping Inclin…
JWST Detects Neon Line Variability in a Protoplanetary Disk
C. C. Espaillat, T. Thanathibodee, C. V. Pittman +6
We report the first detection of variability in the mid-infrared neon line emission of a protoplanetary disk by comparing a JWST MIRI MRS spectrum of SZ Cha taken in 2023 with a Sp…
A JWST inventory of protoplanetary disk ices: The edge-on protoplanetary disk HH 48 NE, seen with the Ice Age ERS program
J. A. Sturm, M. K. McClure, T. L. Beck +24
Ices are the main carriers of volatiles in protoplanetary disks and are crucial to our understanding of the chemistry that ultimately sets the organic composition of planets. The E…
The edge-on protoplanetary disk HH 48 NE II. Modeling ices and silicates
J. A. Sturm, M. K. McClure, J. B. Bergner +11
The abundance and distribution of ice in protoplanetary disks (PPD) is critical to understand the linkage between the composition of circumstellar matter and the composition of exo…
The edge-on protoplanetary disk HH 48 NE I. Modeling the geometry and stellar parameters
J. A. Sturm, M. K. McClure, C. J. Law +11
Context. Observations of edge-on disks are an important tool for constraining general protoplanetary disk properties that cannot be determined in any other way. However, most radia…
Disentangling protoplanetary disk gas mass and carbon depletion through combined atomic and molecular tracers
J. A. Sturm, A. S. Booth, M. K. McClure +2
The total disk gas mass and elemental C, N, O composition of protoplanetary disks are crucial ingredients for our understanding of planet formation. Measuring the gas mass is compl…
Gas temperature structure across transition disk cavities
M. Leemker, A. S. Booth, E. F. van Dishoeck +8
[Abridged] Most disks observed at high angular resolution show substructures. Knowledge about the gas surface density and temperature is essential to understand these. The aim of t…
Tracing pebble drift and trapping using radial carbon depletion profiles in protoplanetary disks
J. A. Sturm, M. K. McClure, D. Harsono +5
The composition of planets may be largely determined by the chemical processing and accretion of icy pebbles in protoplanetary disks. Recent observations of protoplanetary disks hi…
