Characterization of the MUSE NFM PSF as a function of atmospheric conditions: TipTop calibration

Enrico Congiu, Fuyan Bian, Carlo F. Manara +8

The Multi Unit Spectroscopic Explorer (MUSE) achieves exceptional spatial resolution in narrow-field mode (NFM) thanks to the GALACSI adaptive optics (AO) system. However, limitati…

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…

A closer look at the WISPIT 2 host star. Evidence for a spectroscopic binary

Cade J. Bürgy, Myriam Benisty, Hala Alqubelat +2

While hundreds of protoplanetary discs have been studied in great detail, the detection of protoplanets still embedded in their native discs remains rare. WISPIT 2 is only the seco…

From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius

Chengyan Xie, Ilaria Pascucci, Feng Long +23

We present JWST/MIRI spectroscopy of 14 disks in the older (~5-10 Myr) Upper Scorpius (USco) association and use slab of gas in local thermal equilibrium to infer basic gas propert…

Chemical Divergence and Water Depletion: Gas Properties of Evolved Upper Scorpius Disks Revealed by JWST/MIRI

Eshan Raul, Ke Zhang, Abygail Waggoner +25

Tracing the chemical evolution of protoplanetary disks over time requires observations of disks at different ages. However, most JWST/MIRI surveys published to date have targeted y…

X-Shooter survey of disk accretion in Upper Scorpius II. A lack of correlation between accretion rates and disk properties

A. Empey, C. F. Manara, R. Garcia Lopez +20

The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star forming regions of different ages and proper…
