The GAPS programme at TNG XLIX. TOI-5398, the youngest compact multi-planet system composed of an inner sub-Neptune and an outer warm Saturn

G. Mantovan, L. Malavolta, S. Desidera +68

Short-period giant planets are frequently found to be solitary compared to other classes of exoplanets. Small inner companions to giant planets with 15 days are known…

The GAPS programme at TNG XXXIV. Activity-rotation, flux-flux relationships, and active region evolution through stellar age

J. Maldonado, S. Colombo, A. Petralia +26

Active region evolution plays an important role in the generation and variability of magnetic fields on the surface of lower main-sequence stars. However, determining the lifetime…

HADES RV programme with HARPS-N at TNG XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period

J. Maldonado, A. Petralia, M. Damasso +27

Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the short-term activity of t…

Post conjunction detection of Pictoris b with VLT/SPHERE

A. -M. Lagrange, A. Boccaletti, M. Langlois +102

With an orbital distance comparable to that of Saturn in the solar system, \bpic b is the closest (semi-major axis \,9\,au) exoplanet that has been imaged to orbit a star.…

The GAPS Programme with HARPS-N@TNG XII: Characterization of the planetary system around HD108874

S. Benatti, S. Desidera, M. Damasso +36

In order to understand the observed physical and orbital diversity of extrasolar planetary systems, a full investigation of these objects and of their host stars is necessary. With…

First light of the VLT planet finder SPHERE. IV. Physical and chemical properties of the planets around HR8799

M. Bonnefoy, A. Zurlo, J. L. Baudino +63

The system of four planets around HR8799 offers a unique opportunity to probe the physics and chemistry at play in the atmospheres of self-luminous young (~30 Myr) planets. We rece…
