      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). ...

    • Parallaxes and Infrared Photometry of three Y0 dwarfs 

      Smart, R. L.; Apai, Dániel; Kirkpatrick, J. Davy; Leggett, S.K.; Marocco, F.; Morrison, Jane E.; Jones, H. R. A.; Pinfield, D.; Tremblin, P.; Amundsen, D. S. (2017-03-24)
      We have followed up the three Y0 dwarfs WISEPA J041022.71+150248.5, WISEPA J173835.53+273258.9 and WISEPC J205628.90+145953.3 using the UKIRT/WFCAM telescope/instruments. We find parallaxes that are more consistent and ...
