Gálvez, M. C. ; Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | IOP publishing ltd | 2009-04This paper describes a multiwavelength optical study of chromospheres in two X-ray/EUV-selected active binary stars with strong H alpha emission, V789 Mon (2RE J0725-002) and GZ Leo (2RE J1101+223). The goal of the study is to determine radial v[...]![]()

Cornide Castro-Piñeiro, Manuel ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Armentia, J. A. ; Reglero, V. | IOP publishing ltd | 1992-04High dispersion spectra have been obtained in order to study the activity level of ten barium stars by means of the Ca II H and K emission flux, looking for a relation between barium intensity index and activity. Absolute magnitudes obtained fro[...]![]()

Barrado y Navascués, D. ; Fernández Figueroa, María José ; Montesinos, B. ; Castro Rubio, Elisa de | EDP Sciencies | 1994-10In this paper we present a study of the evolutionary status of a sample of chromospherically active binary systems for which accurate determinations of their stellar parameters are available. Stellar ages have been obtained by using evolutionary[...]![]()

Barrado y Navascués, D. ; Castro Rubio, Elisa de ; Fernández Figueroa, María José ; Cornide Castro-Piñeiro, Manuel ; García López, R. J. | EDP Sciencies | 1998-09-20We present a study of the lithium abundances of a sample of evolved components of Chromospherically Active Binary Systems. We show that a significant part of them have lithium excesses, independently of their mass and evolutionary stage. Therefo[...]![]()

Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Rego Fernández, Manuel | EDP Sciencies | 1981Observations of ? Ceti (HD 20630), G5 V, obtained with the IUE satellite have been analysed to determine the structure of its outer atmosphere. This analysis is used to derive a model of transition region and to examine the terms of energy balan[...]![]()

Reglero, V. ; Fernández Figueroa, María José ; Giménez, A. ; Castro Rubio, Elisa de ; Fabregat, J. ; Cornide Castro-Piñeiro, Manuel ; Armentia, J. E. | EDP Sciences | 1991-06A detailed study of the system V772 Her = HD 165590 = ADS 11060 AB is presented. The three identified components are found to be late type stars close to the zero-age main sequence with high rotational velocities. Spectroscopic observations allo[...]![]()

Gómez de Castro, Ana Inés ; López-Santiago, Javier ; Sestito, Paola ; Rodrigo Gudiel, Víctor ; López Martínez, Fátima ; Castro Rubio, Elisa de ; Cornide, Manuel ; Yáñez, Javier | Springer | 2011-09The Gould Belt is the local superassociation of star formation. The age of the Belt is some few 10(7) yr, henceforth, its population is dominated by luminous young OB associations and low mass pre-main sequence stars. Attempts to unveil the low [...]![]()

Gómez de Castro, Ana Inés ; López Santiago, Javier ; López Martínez, Fátima ; Sánchez, Néstor ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | Wiley | 2015-06-01The Taurus-Aurigamolecular complex (TMC) is the main laboratory for the study of low-mass star formation. The density and properties of interstellar dust are expected to vary across the TMC. These variations trace important processes such as dus[...]
