Martínez Arnáiz, R. M. ; Maldonado, J. ; Montes Gutiérrez, David ; Eiroa, C. ; Montesinos, B. ; Ribas, I. ; Solano, E. | American Institute of Physics | 2009We present the most recent results of our ongoing long-term high resolution spectroscopic study of nearby (d ? 25 pc) FGK stars which aim is to characterize the local properties of the Galaxy, in particular the star-formation history. A through [...]texto impreso

M. ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 2010-05Aims. We present a compilation of spectroscopic data from a survey of 144 chromospherically active young stars in the solar neighborhood, which may be used to investigate different aspects of its formation and evolution in terms of kinematics an[...]texto impreso
Montes Gutiérrez, David ; López Santiago, J. ; Martínez Arnáiz, R. M. ; Guillout, P. ; Klutsch, A. ; Freire Ferrero, R. ; Frasca, A. ; Marilli, E. | American Institute of Physics | 2009Post T Tauri stars (PTTS) are late-type stars in the age range between 10 and 100 Myr filling the gap between T Tauri (TTs) and zero-age: main sequence phases. This period of evolution remains ambiguous and until now different studies of young s[...]texto impreso
Maldonado, J. ; Martínez Arnáiz, R. M. ; Eiroa, C. ; Montes Gutiérrez, David ; Montesinos, B. | EDP Sciencies | 2010-10Context. Nearby late-type stars are excellent targets for seeking young objects in stellar associations and moving groups. The origin of these structures is still misunderstood, and lists of moving group members often change with time and also f[...]
