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…

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…
