JWST/MIRI coronagraphic search for planets in systems with gapped exoKuiper belts and proper motion anomalies

R. Bendahan-West, S. Marino, A. L. Carter +17

Over the past decade, ALMA has uncovered a range of substructures within exoKuiper belts, pointing to a population of undetected planets. With JWST's sensitivity, we now have the o…

The GAPS Programme at TNG LXVIII. Characterization of the outer substellar companion around HD 72659 with a multi-technique approach

A. Ruggieri, A. Sozzetti, S. Desidera +23

Before discovering the first exoplanets, the Radial Velocity (RV) method had been used for decades to discover binary stars. Despite significant advancements in this technique, it…

The HOSTS Survey: Suspected variable dust emission and constraints on companions around θ Boo

G. Garreau, D. Defrère, S. Ertel +23

During the HOSTS survey by the LBTI, an excess emission from the main sequence star θ Boo (F7V spectral type, 14.5pc distance) was observed. This excess indicates the presence of e…

Protoplanetary disk insights from the first ERIS/APP survey at 4 μm

F. Maio, V. Roccatagliata, D. Fedele +17

We present high-contrast imaging observations of seven protoplanetary disks at 4um using the ERIS on the VLT. This study focuses on detecting scattered light from micron-sized dust…

A study of the frequency and characteristics of stellar companions and Jupiter-like planets in nearby open clusters

R. Gratton, M. Bonavita, D. Mesa +9

Observations of companions of solar-type stars in nearby young moving groups (NYMGs) show that they split into two groups: stellar and brown dwarf companions (mass ratio )…

A multi-technique detection of an eccentric giant planet around accelerating star HD 57625

D. Barbato, D. Mesa, V. D'Orazi +42

The synergy between different detection methods is a key asset in exoplanetology, allowing for both precise characterization of detected exoplanets and robust constraints even in t…

Deep imaging of three accelerating stars using SHARK-NIR and LMIRCam at LBT

D. Mesa, R. Gratton, V. D'Orazi +29

The combination of detection techniques enhances our ability to identify companions orbiting nearby stars. We employed high-contrast imaging to constrain mass and separation of pos…

Giant planets population around B stars from the first part of the BEAST survey

P. Delorme, A. Chomez, V. Squicciarini +23

Exoplanets form from circumstellar protoplanetary discs whose fundamental properties (notably their extent, composition, mass, temperature and lifetime) depend on the host star pro…

Implications of the discovery of AF Lep b: The mass-luminosity relation for planets in the Pic Moving Group and the L-T transition for young companions and free-floating planets

R. Gratton, M. Bonavita, D. Mesa +7

Dynamical masses of young planets aged between 10 and 200 Myr detected in imaging play a crucial role in shaping models of giant planet formation. Regrettably, only a few such obje…

Atmospheric properties of AF Lep b with forward modeling

P. Palma-Bifani, G. Chauvin, D. Borja +11

Aims. We aim to expand the atmospheric exploration of AF Lep b by modeling all available observations obtained with SPHERE at VLT (between 0.95-1.65, at 2.105, and 2.253 m, and…

The SPHERE infrared survey for exoplanets (SHINE) -- II. Observations, Data reduction and analysis Detection performances and early-results

M. Langlois, R. Gratton, A. -M. Lagrange +118

Over the past decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) from their host stars. To understand…

First scattered light detection of a nearly edge-on transition disk around the T Tauri star RY Lup

M. Langlois, A. Pohl, A. -M. Lagrange +41

Transition disks are considered sites of ongoing planet formation, and their dust and gas distributions could be signposts of embedded planets. The transition disk around the T Tau…

Shadows and spirals in the protoplanetary disk HD 100453

M. Benisty, T. Stolker, A. Pohl +46

Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form. We observed and spatially resolv…

Direct detection of scattered light gaps in the transitional disk around HD 97048 with VLT/SPHERE

C. Ginski, T. Stolker, P. Pinilla +28

We studied the well known circumstellar disk around the Herbig Ae/Be star HD 97048 with high angular resolution to reveal undetected structures in the disk, which may be indicative…
