Impact of accretion variability on the CO emission of a disk around a very-low-mass star with JWST

C. Bergez-Casalou, B. Tabone, Y. Aoyama +14

Studying the structure of very-low-mass stars () protoplanetary disk is crucial to understand the formation of Earth-like planets. In this paper, we characteriz…

Hydrogen Line Emission in Accreting Low-Mass Objects I: Spectral Analysis of Shock-Origin Narrow Component

Yuhiko Aoyama, Jun Hashimoto, Gabriel-Dominique Marleau +5

Hydrogen lines are widely used as tracers of stellar and planetary accretion. In classical T~Tauri stars, hydrogen lines are usually interpreted as arising from magnetospheric accr…

The Contribution of Starspots to the Lithium Spread in NGC 2264

Yan Luo, Gregory J. Herczeg, Min Fang +2

Star clusters with ages of a few Myr have a previously unexplained dispersion in the lithium equivalent widths. In this work, we show that much of the lithium spread of the young c…

The FU Ori outburst of PR Ori B

Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42

We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…

A superflare of BP Tau simultaneously caught by EP X-ray and TESS optical observations

Xingyu Zhou, Mingjun Liu, Gregory J. Herczeg +10

Multiwavelength observations of stellar flares trace the activity of different components of the stars' outer atmosphere, providing insight into their interactions. In the present…

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…
