Two planets for the young star HD 63433. The study: “The GAPS Programme at TNG XLII. A characterisation study of the multi-planet system around the 400 Myr-old star HD 63433 (TOI-1726)” of M. Damasso (INAF – OATo) appeared on A&A

The search and characterization of exoplanets around young stars (where “young” here means less than 600 million years) is crucial for advancing our understanding of planetary formation processes and the early stages of planet evolution. During this phase, the planetary environment is significantly more turbulent compared to that of mature exoplanetary systems. For example, many planets in young systems continue

Developed a method to account for spots and limb darkening to retrieve exoplanets atmospheric spectra. The study: “Correcting the effect of stellar spots on ARIEL transmission spectra – II. The limb-darkening effect” of G. Cracchiolo (INAF – OAPA/UNIPA) recently appeared on MNRAS

To date, exoplanetary transits have allowed astronomers to discovery more than 70% of known exoplanets. Besides, by analysing stellar spectra acquired during the transits it is possible to study the atmospheres of the transiting exoplanet. During the transit, in fact, the planet is crossing the stellar disc, causing a small and periodic dimming of stellar observed flux. If the exoplanet

Stars more massive than 9 solar masses end their evolution in spectacular supernova explosions. These explosions are triggered by the gravitational collapse of the core of such massive stars, once the thermonuclear reactions are exhausted and the core is not supported against gravity by the pressure produced by the reactions. Supernovae are not simple spherical explosions, but rather complex phenomena

3DMAP-VR: a project to develop 3D astrophysical models for Virtual Reality

The development of numerical models is a powerful method to explore properties and evolution of astrophysical objects, mainly for remote objects or when the necessary spatial details are higher than the resolution of modern telescopes. These models can be both hydrodynamical or magneto-hydrodynamical, depending on the importance of the effects related to the magnetic fields. In the last years, the

The final architecture of a planetary system is the result of a complex interplay between several processes, such as the dispersion of the protoplanetary disk from which the planetary system formed, and the gravitational interaction between the newborn planets. Besides, these processes can be affected by the environment and by their central star. One of the most important process dictating
