EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53
Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19
We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…
Characterizing the Extended Molecular Hydrogen Winds in Protoplanetary Disks from the JWST Disk Infrared Spectroscopic Chemistry Survey
Mayank Narang, Klaus M. Pontoppidan, Colette Salyk +14
We present a comprehensive analysis of extended H emission from 34 protoplanetary disks observed with the JWST Disk Infrared Spectroscopic Chemistry Survey (JDISCS), supplement…
An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results
Sean K. Terry, Jay Anderson, Charles A. Beichman +13
We present an HST imaging survey of a 1.1 sq. degree sky area toward the Milky Way Galactic Bulge. This field significantly overlaps with the upcoming Nancy Grace Roman Galactic Bu…
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…
The JDISC Survey: Linking the Physics and Chemistry of Inner and Outer Protoplanetary Disk Zones
Nicole Arulanantham, Colette Salyk, Klaus Pontoppidan +20
Mid-infrared spectroscopy of protoplanetary disks provides a chemical inventory of gas within a few au, where planets are readily detected around older stars. With the JWST Disk In…
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…
JWST/MIRI detection of a carbon-rich chemistry in a solar nebula analog
Maria Jose Colmenares, Edwin Bergin, Colette Salyk +16
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their…
Water-Rich Disks around Late M-stars Unveiled: Exploring the Remarkable Case of Sz114
Chengyan Xie, Ilaria Pascucci, Feng Long +18
We present an analysis of the JDISC JWST/MIRI-MRS spectrum of Sz~114, an accreting M5 star surrounded by a large dust disk with a shallow gap at au. The spectrum is molec…
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…
Grain growth in newly discovered young eruptive stars
Á. Kóspál, P. Ábrahám, A. Carmona +4
FU Orionis-type stars are young stellar objects showing large outbursts due to highly enhanced accretion from the circumstellar disk onto the protostar. FUor-type outbursts happen…
Mass measurements in protoplanetary disks from hydrogen deuteride
Melissa McClure, Ted Bergin, Ilse Cleeves +8
The total gas mass of a protoplanetary disk is a fundamental, but poorly determined, quantity. A new technique \citep{bergin+13} has been demonstrated to assess directly the bulk m…
