Variability and magnetic activity in pre-Main Sequence stars. The study: “CSI2264: Simultaneous optical and X-ray variability in the pre-main sequence stars of NGC2264. II: Photometric variability, magnetic activity, and rotation in class III objects and stars with transition disks” of M. G. Guarcello (INAF-OAPA) recently appeared in A&A

Pre-Main Sequence stars are young stars whose cores are not dense and hot enough to ignite the thermonuclear reactions that will power them for the rest of their evolution. These stars are sorted in three classes: the youngest stars are the class I sources, still embedded in an accreting envelope of gas; class II stars have dispersed their accreting envelope

LSST (Large Synoptic Survey Telescope) is the future of the astronomy in the time domain. LSST is a new-generation telescope that will be built on Cerro Pachon in Chile (2700 meters). It will be equipped with a primary mirror of 8.4 meters of diameter and an innovative camera able to observe an very large field of view, more than 49

Observing how the light emitted by stars changes with the time can be an interesting hobby, but it can also be something more important: an important and powerful diagnostic for something that can be hardly studied with some other approach…   This can be particularly important for pre-main sequence stars with protoplanetary disks. In these stars, in fact, important and
