Investigating the Nested Structure of the Outflow from the Low Luminosity Protostar IRAS 16253-2429 using JWST and ALMA

Mayank Narang, Himanshu Tyagi, Nagayoshi Ohashi +37

Understanding the earliest stage of star and planet formation requires detailed observations to address the connection and interplay between the accretion, outflow and disk evoluti…

The influence of tight binaries on proto-planetary disk masses

Kevin Flaherty, Peter Knowlton, Tasan Smith-Gandy +5

Binary systems are a common site of planet formation, despite the destructive effects of the binary on the disk. While surveys of planet forming material have found diminished disk…

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…

Coordinated Space and Ground-Based Monitoring of Accretion Bursts in a Protoplanetary Disk: Establishing Mid-Infrared Hydrogen Lines as Accretion Diagnostics for JWST-MIRI

Benjamin M. Tofflemire, Carlo F. Manara, Andrea Banzatti +17

In this paper, we establish and calibrate mid-infrared hydrogen recombination lines observed with JWST as accretion tracers for pre-main-sequence stars that accrete from circumstel…

JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices

Himanshu Tyagi, Manoj P., Mayank Narang +35

The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…

A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. III. Optical Spectra

John Wendeborn, Catherine C. Espaillat, Thanawuth Thanathibodee +20

Classical T Tauri Stars (CTTSs) are highly variable stars that possess gas- and dust-rich disks from which planets form. Much of their variability is driven by mass accretion from…
