Exploring the radial velocity variations of RY Lup with VLT/ESPRESSO: Binary versus spot hypotheses
Hala Alqubelat, Claudia Di Maio, Antonio Frasca +7
The paper analyzes high‑resolution VLT/ESPRESSO spectra of the T Tauri star RY Lup to determine whether its radial‑velocity variations are caused by a close binary companion or ste…
Direct Optical Evidence of Late-Stage Infall in AB Aurigae: A Stagnant [O I] Reservoir and a Crushed Magnetosphere
Dipen Sahu, Rishikesh Sharma, Shubhendra Nath Das +2
Massive planet-carved cavities in transition disks should theoretically throttle inward gas transport, challenging our understanding of how central stars maintain vigorous accretio…
Lithium and the evolution of intermediate-mass T Tauri and Herbig stars. Rotation, accretion, and planets
I. MendigutÃa, J. Campbell-White, B. Montesinos +9
(Abridged) We contribute to our understanding of the evolution of young intermediate-mass stars by providing a comprehensive analysis of their lithium (Li) content. A sample of 71…
PENELLOPE: IX. Lithium, iron and barium elemental abundances in eight nearby young clusters
R. Carini, K. Biazzo, A. Frasca +19
We conducted a homogeneous chemical analysis of pre-main sequence stars with effective temperatures ranging from 3000 K to 5500 K in eight nearby star-forming regions…
Young system development in a cometary globule: An investigation into the eccentric disk around AT Pyx in terms of planet-formation and interaction with its surrounding environment
Dan McLachlan, Christian Ginski, Jake Byrne +5
This paper presents new data and analyses of the AT Pyx system, a disk-hosting young star located in a cometary globule in the Gum Nebula. This radiation-driven structure is an unu…
Coordinated Space- and Ground-based Monitoring of Accretion Bursts in a Protoplanetary Disk: The Orbital and Accretion Properties of DQ Tau
Hala Alqubelat, Carlo F. Manara, Justyn Campbell-White +9
Multiplicity in pre-main-sequence (PMS) systems shapes circumstellar and circumbinary disks, often producing features such as inner cavities, spiral arms, and gas streamers that fa…
