HO in the terrestrial planet-forming regions of protoplanetary disks
Colette Salyk, Klaus M. Pontoppidan, Ke Zhang +12
Isotopologues play an important role in solar system cosmochemistry studies, revealing details of early planet formation physics and chemistry. Oxygen isotopes, as measured in sola…
JWST's sharper view of EX Lup: cold water from ice sublimation during accretion outbursts
Sarah A. Smith, Carlos E. Romero-Mirza, Andrea Banzatti +9
The unstable accretion phases during pre-main-sequence evolution of T Tauri stars produce variable irradiation and heating of planet-forming regions. A strong accretion outburst wa…
The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase
Feng Long, Ilaria Pascucci, Adrien Houge +20
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16262756.1B (hereafter J0446B), an old (34 Myr) M4.5 star but with hints of ongoing accretion. The sp…
Retrieval of Thermally-Resolved Water Vapor Distributions in Disks Observed with JWST-MIRI
Carlos E. Romero-Mirza, Andrea Banzatti, Karin I. Öberg +13
The mid-infrared water vapor emission spectrum provides a novel way to characterize the delivery of icy pebbles towards the innermost ( au) regions of planet-forming disks. Rec…
Water in protoplanetary disks with JWST-MIRI: spectral excitation atlas and radial distribution from temperature diagnostic diagrams and Doppler mapping
Andrea Banzatti, Colette Salyk, Klaus M. Pontoppidan +19
This work aims at providing fundamental general tools for the analysis of water spectra as observed in protoplanetary disks with JWST-MIRI. We analyze 25 high-quality spectra from…
JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk
Carlos E. Romero-Mirza, Karin I. Öberg, Andrea Banzatti +24
We present MIRI MRS observations of the large, multi-gapped protoplanetary disk around the T-Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9 to 25…
High-contrast JWST-MIRI spectroscopy of planet-forming disks for the JDISC Survey
Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +26
The JWST Disk Infrared Spectral Chemistry Survey (JDISCS) aims to understand the evolution of the chemistry of inner protoplanetary disks using the Mid-InfraRed Instrument (MIRI) o…
Where are the Water Worlds?: Self-Consistent Models of Water-Rich Exoplanet Atmospheres
Eliza M. -R. Kempton, Madeline Lessard, Matej Malik +5
It remains to be ascertained whether sub-Neptune exoplanets primarily possess hydrogen-rich atmospheres or whether a population of HO-rich "water worlds" lurks in their midst.…
Cold Deuterium Fractionation in the Nearest Planet-Forming Disk
Carlos E. Romero-Mirza, Karin I. Öberg, Charles J. Law +7
Deuterium fractionation provides a window to the thermal history of volatiles in the solar system and protoplanetary disks. While evidence of active molecular deuteration has been…
Mapping Protoplanetary Disk Vertical Structure with CO Isotopologue Line Emission
Charles J. Law, Richard Teague, Karin I. Öberg +21
High spatial resolution observations of CO isotopologue line emission in protoplanetary disks at mid-inclinations (30-75°) allow us to characterize the gas structure in…
