A Multiwavelength, Multiepoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. I. HST Far-UV and Near-UV Spectra

The Astrophysical Journal
The classical T Tauri star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion processes, which can dictate future stellar evolution and planet formation, a multiepoch ...

LAMOST Young Stellar Objects. I. Spectroscopically Identifying and Characterizing M-type YSOs

The Astrophysical Journal
This study utilized Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) low-resolution spectra to identify M-type young stellar objects (YSOs) and characterize their accretion signatures.

The Identification of New Herbig Ae/Be Stars from LAMOST DR7

The Astronomical Journal
Herbig Ae/Be stars (HAeBes) are critical tracers of intermediate- and high-mass star formation, yet their census remains incomplete compared to low-mass young stellar objects like T-Tauri stars.

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.
