The 2023 Outburst of the Gaia Alerted EXor Gaia23bab

The Astrophysical Journal
Episodic accretion is a fundamental process in the build-up of the stellar mass. EX Lupi-type eruptive young stars (EXors) represent one of the main types of episodic accretion. We study the recently discovered EXor Gaia23bab during its 2023 outburst. We

JWST Reveals Carbon-rich Chemistry in a Transitional Disk

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

The ODYSSEUS Survey. Spatial Correlation of Magnetospheric Inclinations Points to Parsec-scale Star–Cloud Connection

The Astrophysical Journal Letters
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 significant influence are not well constrained.

Peculiar Disk Substructures Associated with the Young Eruptive Star EX Lupi

The Astrophysical Journal
Young eruptive stars such as EXors undergo dramatic accretion outbursts characterized by sudden optical brightenings, yet the underlying physical mechanism remains uncertain.

Broadening the Canonical Picture of EUV-driven Photoevaporation of Accretion Disks

The Astrophysical Journal
Photoevaporation driven by hydrogen-ionizing extreme-ultraviolet (EUV) radiation profoundly shapes the lives of diverse astrophysical objects. We construct an analytical model accounting for the finite timescales of photoheating and photoionization and ...
