Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
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…
ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) III. Optical He I line profiles of the accreting super Jupiter Delorme 1 (AB)b
Gayathri Viswanath, Mickaël Bonnefoy, Catherine Dougados +8
High-resolution spectroscopic observations of helium emission lines provide a powerful probe of accretion geometry in classical T Tauri stars, revealing regions not well traced by…
The GRAVITY young stellar object survey -- XV. The star-disk interaction region of the T Tauri star DO Tau
GRAVITY Collaboration, K. Perraut, J. Bouvier +61
Protoplanetary disks around young Sun-like stars are the cradles of the vast majority of detected exoplanets. Probing these disks at multiple spatial scales is key to uncovering ho…
ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) - II. Time series of Balmer line profiles of Delorme 1(AB)b
Dorian Demars, Mickaël Bonnefoy, Catherine Dougados +14
Accretion processes in the planetary-mass regime remain poorly constrained, yet they strongly influence planet formation, evolution, and the composition of circumplanetary disks (C…
GPI+SPHERE detection of a 6.1 circumbinary planet around HD 143811
Vito Squicciarini, Johan Mazoyer, Christian Wilkinson +6
Owing to its sensitivity to wide-orbit giant exoplanets, direct imaging is uniquely positioned to shed light on the interplay between protoplanetary disks and stellar hosts. In add…
