Analysis of combined radial velocities and activity of BD+20 1790: : evidence supporting the existence of a planetary companion
Hernán-Obispo, M.; Tuomi, Mikko; Gálvez-Ortiz, M. C.; Golovin, A.; Barnes, J. R.; Jones, Hugh; Kane, S. R.; Pinfield, D.; Jenkins, J. S.; Petit, P.; Anglada-Escudé, G.; Marsden, S. C.; Catalán, S.; Jeffers, S. V.; Castro, E. de; Cornide, M.; Garcés, A.; Jones, M. I.; Gorlova, N.; Andreev, M. (2015-04-01)This paper presents the simultaneous Bayesian analysis of the radial velocity and activity indices for the K5Ve active star BD+20 1790, that was proposed to host a close-in massive planet by Hern\'an-Obispo et al. (2010). ... -
BD+20 1790 b : chronicle of an exoplanetary discovery
Hernan-Obispo, M.; Galvez-Ortiz, M.C.; Anglada-Escude, G.; Kane, S.R.; De Castro, E.; Cornide, M. (American Institute of Physics (AIP), 2009)In this contribution we report evidence for a planetary companion around a young and active late-type K star. Our group has been developing a study of stellar activity and kinematics for this star over the past years. ... -
Evidence of a massive planet candidate orbiting the young active K5V star BD+20 1790
Hernan-Obispo, M.; Galvez-Ortiz, M.C.; Anglada-Escude, G.; Kane, S.R.; Barnes, J.R.; De Castro, E.; Cornide, M. (2010)Context. BD+20 1790 is a young active, metal-rich, late-type K5Ve star. We have undertaken a study of stellar activity and kinematics for this star over the past few years. Previous results show a high level of stellar ... -
A high-resolution spectroscopic survey of late-type stars: chromospheric activity, rotation, kinematics, and age
Lopez-Santiago, J.; Montes, D.; Galvez-Ortiz, M.C.; Crespo-Chacon, I.; Martinez-Arnaiz, R.M.; Fernandez-Figueroa, M.J.; De Castro, E.; Cornide, M. (2010)Aims. 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 ... -
Multiwavelength optical observations of two chromospherically active binary systems: V789 Mon and GZ Leo
Galvez, M.C.; Montes, D.; Fernandez-Figueroa, M.J.; De Castro, E.; Cornide, M. (2009)
