A sparse population of young stars in Cepheus
A. Klutsch, D. Montes, P. Guillout +5
Once mixed in the ambient galactic plane stellar population, young stars are virtually indiscernible because neither their global photometric properties nor the presence of nearby…
Differential rotation on the young solar analogue V889 Herculis
Zsolt Kovari, Antonio Frasca, Katia Biazzo +3
V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging. The 10 FO…
Discovery of "isolated" comoving T Tauri stars in Cepheus
P. Guillout, A. Frasca, A. Klutsch +2
During the course of a large spectroscopic survey of X-ray active late-type stars in the solar neighbourhood, we discovered four lithium-rich stars packed within just a few degrees…
Characterization of Kepler early-type targets
G. Catanzaro, A. Frasca, J. Molenda-Zakowicz +1
Stellar pulsation offers a unique opportunity to constrain the intrinsic parameters of stars and unveil their inner structure. The Kepler satellite is collecting an enormous amount…
Photospheric and chromospheric activity on the young solar-type star HD 171488
A. Frasca, K. Biazzo, Zs. Kovari +2
We present the results of contemporaneous spectroscopic and photometric monitoring of the young solar-type star HD171488 (Prot~1.337 d) aimed at studying surface inhomogeneities at…
