Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel ; Latorre, A. ; Sanz Forcada, J. | EDP Sciences | 2000-10This is the third paper of a series aimed at studying the chromosphere of active binary systems using the information provided for several optical spectroscopic features. High resolution echelle spectra including all the optical chromospheric ac[...]texto impreso
Gálvez, M. C. ; Montes Gutiérrez, David ; Fernández Figueroa, María José ; López Santiago, Javier ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 2002-07We present high resolution echelle spectra taken during four observing runs from 1999 to 2001 of the recently X-ray/EUV selected chromospherically active binary BK Psc (2RE J0039+103). Our observations confirm the single-lined spectroscopic bina[...]texto impreso
Gálvez, M. C. ; Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 2007-09Context. This is the fifth paper in a series aimed at studying the chromospheres of active binary systems using several optical spectroscopic indicators to obtain or improve orbital solution and fundamental stellar parameters. Aims. We present h[...]texto impreso
Sanz Forcada, J. ; Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | Astronomical Society of the Pacific | 1999We present here a continuation of our ongoing project of multiwavelength optical observations aimed at studying the chromosphere of active binary systems using the information provided for several optical spectroscopic features that are formed a[...]texto impreso
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[...]texto impreso
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[...]texto impreso
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[...]texto impreso
Montes Gutiérrez, David ; Fernández Figueroa, María José ; Cornide Castro-Piñeiro, Manuel ; Castro Rubio, Elisa de | EDP Sciencies | 1996-08In this work we analyze the behaviour of the excess Ca II H and K and H_ ? emissions in a sample of 73 chromospherically active binary systems (RS CVn and BY Dra classes), of different activity levels and luminosity classes. This sample includes[...]texto impreso
Montes Gutiérrez, David ; Fernández Figueroa, María José ; Cornide Castro-Piñeiro, Manuel ; Castro Rubio, Elisa de | EDP Sciencies | 1996-08In this work we analyze the behaviour of the excess Ca II H & K and H emissions in a sample of 73 chromospherically active binary systems (RS CVn and BY Dra classes), of diferent activity levels and luminosity classes. This sample includes the [...]texto impreso
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[...]texto impreso
Montes Gutiérrez, David ; Fernández Figueroa, María José ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 1994-05We present measurements of the emission core width W_0 and the wavelength separation of the K_1 dips, W_1, of the Ca II H and K emission lines observed on high-dispersion spectra of 28 chromospherically active binary systems (RS CVn and BY Dra s[...]texto impreso
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[...]texto impreso
