The study of the exoplanets orbiting around young stars (e.g., younger than a few tens of million of years) offer the important opportunity for studying the early evoalutionary phases of those processes that shape the architecture of planetary systems. However, it is quite difficult to detect and study exoplanets around young stars, because of their low number, the complexity of their» Read more
Palermo Astronomical Observatory “Giuseppe S. Vaiana” is one of the research centres of the National Institute for Astrophysics (INAF). It works together with Palermo University through the Department of Physics and Chemistry.
OAPa’s main characteristic is its specific vocation in the field of space astrophysics. The network of activities also involves several frontier research fields both at the national and international level.
The magnetic activity vs. age in binary systems with a white dwarf and a main sequence star. The study: “Main-sequence companions to white dwarfs – II. The age-activity-rotation relation from a sample of Gaia common proper motion pairs” of A. Rebassa-Mansergas (Universitat Politècnica de Catalunya) recently appeared on MNRAS
Several stellar phenomena and evolutionary processes are connected to their magnetic fields. The mechanisms that allow stars to produce their magnetic fields depend on their internal structure and stellar properties. One dominant property is stellar rotation: the faster stars rotate, the more intense their magnetic field and magnetic activity. Since stellar rotation declines with age, it is not surprising that» Read more
A rich and complex planetary system for the star TOI-4010. The paper: “TOI-4010: A System of Three Large Short-period Planets with a Massive Long-period Companion” of M. Kunimoto (MIT) appeared on AJ)
To date (November 2023), we have confirmed the presence of 5539 exoplanets in 4128 planetary systems. These numbers indicate that, in the majority of cases, we have identified one planet per planetary system. This limitation is primarily due to observational constraints, as it remains challenging to detect small exoplanets with long orbital periods (distant from their stars several astronomical units,» Read more
