    • 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 ...

    • FR Cnc revisited : photometry, polarimetry and spectroscopy 

      Golovin, A.; Galvez-Ortiz, M. C.; Hernan-Obispo, M.; Andreev, M.; Barnes, J. R.; Montes, D.; Pavlenko, E.; Pandey, J. C.; Martinez-Arnaiz, R.; Medhi, B. J.; Parihar, P. S.; Henden, A.; Sergeev, A.; Zaitsev, S. V.; Karpov, N. (2012-03)
      This paper is part of a multiwavelength study aimed at using complementary photometric, polarimetric and spectroscopic data to achieve an understanding of the activity process in late-type stars. Here, we present the study ...
