Several times the Solar Dynamic Observatory (SDO) has observed fragments of hot plasma expelled during coronal eruptions which fall back on the Solar surface following trajectories dictated by the interaction with the local magnetic field. These observations have already been studied by the researchers of the Astronomical Observatory of Palermo given their importance for our comprehension of the processes occurring» 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.
Two large projects (GES and CSI-2264) join forces: The study “The Gaia-ESO Survey and CSI 2264: Substructures, disks, and sequential star formation in the young open cluster NGC 2264” of L. Venuti (INAF-OAPA) recently published by A&A
The study of star-forming regions of our Galaxy is one of the main research topic of the Astronomical Observatory of Palermo. This because they can provide crucial information on how large molecular clouds collapse and form stars, on the early stellar evolutionary stages, on the formation of planetary systems, the formation and dispersion of protoplanetary disks, and the history and» Read more
A search for binary systems with GES. The study “The Gaia-ESO Survey: double, triple, and quadruple-line spectroscopic binary candidates” by T. Merle recently appeared on A&A
The study of binary systems plays an important role in several fields of astronomy such as stellar evolution and galactic archeology since it allows direct measurements of stellar parameters such as masses, radii, and luminosities. Multiple stellar systems have typically small angular separation and thus they are not resolved by direct imaging. In these cases spectroscopy is a powerful tool» Read more
