Fernández Figueroa, María José ; Montesinos, B. ; Castro Rubio, Elisa de ; Rego Fernández, Manuel ; Giménez, A. ; Reglero, V. | EDP Sciencies | 1986-11We report here new Ca II H and K emission line fluxes and equivalent widths for seven RSCVn binary systems, observed at several orbital phases. All the stars show enhanced chromospheric activity. With information from available spectra, an in d[...]texto impreso
In this work we analyse the behaviour of 22 members of the RS CVn family whose absolute parameters are known by observation. We have carried out a study in comparison with detached and normal-evolution systems in order to obtain some general pro[...]texto impreso
Reglero, V. ; Giménez, A. ; Fabregat, J. ; de Catro, E. ; Fernández Figueroa, María José ; De Castro, A. | Amer. Inst. Physics | 1988-05From 1984 to 1986 the authors made several observational campaigns at Calar Alto and La Palma Observatories using the uvby and ? photometric systems to monitor a selected sample of late-type variable stars. In this paper they present the ? value[...]texto impreso
Reglero, V. ; Giménez, A. ; Fabregat, J. ; Castro Rubio, Elisa de ; Fernández Figueroa, María José ; Castro, A. de | IOP publishing ltd | 1988-05From 1984 to 1986, we made several observational campaigns at Calar Alto and La Palma Observatories using the uvby and ß photometric systems to monitor a selected sample of late-type variable stars. In this paper we present the ß values for 38 [...]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
Giménez, A. ; Ballester, J. L. ; Reglero, V. ; Fernández Figueroa, María José ; Castro Rubio, Elisa de | IOP publishing ltd | 1986-07Simultaneous uvby and H? photometry of thee noneclipsing double-lined spectroscopic binary TZ CrB, an active binary system with almost unevolved components, is presented. A small amplitude distortion wave (0.012 mag in y) has been found with max[...]texto impreso
Giménez, A. ; Reglero, V. ; De Castro, E. ; Fernández Figueroa, María José | EDP Sciencies | 1991-08New photometric observations, using the uvby and H? systems of 72 northern-hemisphere active binaries are discussed in order to explain the main characteristics of their spectral light intensity distribution. Values of the parameter ?m1 range fr[...]texto impreso
