Photometric/spectroscopic analyses and magnetic activity in young late-type stars
K. Biazzo, A. Frasca, E. Marilli +3
We present the work in progress of a study based on photometric and spectroscopic observations of young Weak-line T Tauri and Post T Tauri stars just attiving on the Zero Age Main…
True solar analogues in the open cluster M67
K. Biazzo, L. Pasquini, P. Bonifacio +2
The solar analogues are fundamental targets for a better understanding of our Sun and Solar System. Notwithstanding the efforts, this research is usually limited to field stars. Th…
Magnetic activity in the young star SAO 51891
K. Biazzo, A. Frasca, E. Marilli +3
We present preliminary results on a study based on contemporaneous photometric and spectroscopic observations of the young K0-1V star SAO 51891. We find that SAO 51891, a possible…
Solar twins in M67
L. Pasquini, K. Biazzo, P. Bonifacio +2
The discovery of true solar analogues is fundamental for a better understanding of the Sun and of the solar system. The open cluster M67 offers a unique opportunity to search for s…
Spots, plages, and flares on lambda Andromedae and II Pegasi
A. Frasca, K. Biazzo, G. Tas +2
We present the results of a contemporaneous photometric and spectroscopic monitoring of lambda And and II Peg aimed at investigating the behavior of surface inhomogeneities in the…
Physical parameters of evolved stars in clusters and in the field from line-depth ratios
K. Biazzo, L. Pasquini, A. Frasca +6
We present a high-resolution spectroscopic analysis of two samples of evolved stars selected in the field and in the intermediate-age open cluster IC 4651, for which detailed measu…
