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…
Astrometric view of companions in the inner dust cavities of protoplanetary disks
Miguel Vioque, Richard A. Booth, Enrico Ragusa +16
Protoplanetary disks with inner dust cavities (often referred to as "transition disks") are potential signposts of planet formation. We use Gaia astrometry to search for planetary…
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…
The likelihood of not detecting cavity-carving companions in transition discs -- A statistical approach
Enrico Ragusa, Giuseppe Lodato, Nicolás Cuello +3
Protoplanetary discs with cavities, also known as ``transition discs'', constitute ~10% of protoplanetary discs at sub-mm wavelengths. Among several explanations, one hypothesis su…
Eccentricity evolution during planet-disc interaction
Enrico Ragusa, Giovanni Rosotti, Jean Teyssandier +3
During the process of planet formation, the planet-discs interactions might excite (or damp) the orbital eccentricity of the planet. In this paper, we present two long ($t\sim 3\ti…
