Some of the 4903 exoplanets discovered and confirmed so far (https://exoplanets.nasa.gov/) orbit very close to their stars. We learnt with the very first planet discovered around a star different than the Sun (51 Pegasi b, discovered in 1995) that planets with very close orbits are possible in nature. 51 Pegasi b, in fact, orbits at about 0.05 Astronomical Units (AU,» 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.
An Italian consortium to study the Space Weather. The paper: “SWELTO — Space WEather Laboratory in Turin Observatory” of A. Bemporad (INAF – AOTo) recently appeared on the INAF Technical Reports
The atmosphere of the Sun hosts a rich variety of magnetic phenomena, which are the consequence of the interaction between the solar magnetic field and the hot and highly ionized solar gas (plasma). The main magnetic phenomena occurring in the photosphere are the sunspots. They appear as dark spots in the bright solar surface, which correspond to regions with intense» Read more
JWST, explanetary transits and starspots. The paper:”Hiding in plain sight: observing planet-starspot crossings with the James Webb Space Telescope” of G. Bruno (INAF – OA Catania) appeared on MNRAS
We typically observe phenomena due to the interaction between the magnetic field of Sun and its plasma, which is the hot (from 5600 K in photosphere to million degrees in the corona) gas with a high level of ionization, on the photosphere, chromosphere, and corona of our star. Some of these magnetic phenomena are starspots, faculae, prominences, and flares. In particular, solar» Read more
