Hot water emission during an outburst in a classical T Tauri star

Zhen Guo, Javier Osses, Vitor Fermiano +34

In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…

A comprehensive Gaia spectroscopic study of stars in the Sco-Cen complex: star formation history and disk lifetime

Min Fang, Gregory J. Herczeg

We re-evaluate the star formation history of the nearby Sco-Cen OB Association with a comprehensive analysis of Gaia XP spectra of more than 7,800 potential members. New spectral c…

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…

GRB Timing: Decoding the Hidden Slow Jets in GRB 060729

Jin-Jun Geng, Ding-Fang Hu, Hao-Xuan Gao +16

Gamma-ray bursts (GRBs) are luminous stellar explosions characterized by the ejection of relativistic jets. This work proposes a novel paradigm to study these GRB jets. By analyzin…

Examining Turbulence in Galactic Molecular Clouds -- I: A Statistical Analysis of Velocity Structures

Yuehui Ma, Miaomiao Zhang, Hongchi Wang +14

We present a systematic analysis of the velocity structure functions (VSFs) of 167 molecular clouds with angular sizes greater than 176 arcmin in three sectors of the Gal…
