      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). ...

    • 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 ...
