López Santiago, Javier ; Miceli, M. ; Valle, M. V. del ; Romero, G. E. ; Bonito, R. ; Albacete Colombo, J. F. ; Pereira, V. ; Castro Rubio, Elisa de ; Damiani, F. | IOP Publishing | 2012-09-20Runaway stars produce shocks when passing through interstellar medium at supersonic velocities. Bow shocks have been detected in the mid-infrared for several high-mass runaway stars and in radio waves for one star. Theoretical models predict the[...]![]()

Hernán Obispo, M. ; Castro Rubio, Elisa de ; Cornide Castro-Piñeiro, Manuel | EDP Sciencies | 2015-04Context. In a previous paper we reported a planetary companion to the young and very active K5Ve star BD+20 1790. We found that this star has a high level of stellar activity (log R'_HK = -3.7) that manifests in a plethora of phenomena (starspot[...]![]()

F. ; Benaglia, P. ; Castro Rubio, Elisa de | IOP Publishing | 2013-10-20Protostellar jets appear at all stages of star formation when the accretion process is still at work. Jets travel at velocities of hundreds of km s^-1, creating strong shocks when interacting with the interstellar medium. Several cases of jets h[...]![]()

In this work we try to establish a connection between the dynamo effect, which operates in the convection zone of late-type stars, and the chromospheric activity observed in these objects. We estímate in a theoretical way, for a sample of main-s[...]![]()
