Indications of Rapid Dust Formation in the Inner Region of a Protoplanetary Disk

Thanawuth Thanathibodee, Catherine Espaillat, Nuria Calvet +4

We report a significant increase in mid-infrared emission m in a transitional disk. The 2024 JWST/MIRI observation of the disk around CVSO 1942 reveals flux increase b…

IPA. Accretion rate of a low-mass Class 0 protostar, measured via mid-infrared fluorescent OH emission

Dan M. Watson, Mayank Narang, Caeley V. Pittman +41

The earliest stages of star formation are highlighted by complex interactions between accretion, outflow, and radiative processes, which shape the chemical and physical environment…

JWST Reveals Carbon-rich Chemistry in a Transitional Disk

M. Volz, C. C. Espaillat, C. V. Pittman +6

We present JWST-MIRI Medium Resolution Spectrometer (MRS) observations of the Classical T Tauri stars GM Aur and RX J1615.3-3255 (J1615), both hosting transitional disks. Despite t…

The ODYSSEUS Survey. Spatial correlation of magnetospheric inclinations points to parsec-scale star-cloud connection

Caeley V. Pittman, Catherine C. Espaillat, Thanawuth Thanathibodee +3

The properties of stars and planets are shaped by the initial conditions of their natal clouds. However, the spatial scales over which the initial conditions can exert a significan…

The ODYSSEUS Survey. Using accretion and stellar rotation to reveal the star-disk connection in T Tauri stars

Caeley V. Pittman, C. C. Espaillat, Zhaohuan Zhu +4

Classical T Tauri stars (CTTS) exhibit strong variability over timescales of minutes to decades. However, much theoretical work assumes that CTTS are in stable spin states. Here, w…

The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars

Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20

Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
