cds-question@unistra.frlate-type-starssolar-system-planetsradial-velocityIn a previous paper we reported a planetary companion to the young and very active K5Ve star BD+20 1790. This paper aims to more rigorously assess the nature of the radial velocity measurements with an expanded data set and new methods of analysis. We have employed Bayesian methods to simultaneously analyse the radial velocity and activity measurements based on a combined data set that includes new and previously published observations.2015A&A...576A..66Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/576/A66CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/512/A45 : Radial velocities of BD+20 1790 (Hernan-Obispo+, 2010)http://www.astrouw.edu.pl/asas : ASAS-3 cataloguehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/576/A66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/576/A66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/576/A66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/576/A66https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/576/A66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/576/A66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/576/A66/photomTerskol photometry of BD+20 1790recnoRecord number assigned by the VizieR team.
