Activity cycles in members of young loose stellar associations
E. Distefano, A. C. Lanzafame, A. Lanza +2
Magnetic cycles have been detected in tens of solar-like stars. The relationship between the cycle properties and global stellar parameters is not fully understood yet. We searched…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Impact of photometric variability on age and mass determination of Young Stellar Objects: A case study on Orion Nebula Cluster
Sergio Messina, Padmakar S. Parihar, Elisa Distefano
In case of pre-main sequence objects, the only way to determine age and mass is by fitting theoretical isochrones on color-magnitude (alternatively luminosity-temperature) diagrams…
