cds-question@unistra.frasteroseismologygiant-starsastronomical-modelsvisible-astronomyThe stellar inclination angle - the angle between the rotation axis of a star and our line of sight - provides valuable information in many different areas, from the characterization of the geometry of exoplanetary and eclipsing binary systems to the formation and evolution of those systems. We propose a method based on asteroseismology and a Bayesian hierarchical scheme for extracting the inclination angle of a single star. This hierarchical method therefore provides a means to both accurately and robustly extract inclination angles from red giant stars. We successfully apply this technique to an artificial data set with an underlying isotropic inclination angle distribution to verify the method. We also apply this technique to 123 red giant stars observed with Kepler. We also show the need for a selection function to account for possible population-level biases, which are not present in individual star-by-star cases, in order to extend the hierarchical method towards inferring underlying population inclination angle distributions.2019MNRAS.488..572Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/572CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/765/L41 : Asteroseismic classification of KIC objects (Stello+, 2013)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/488/572https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/488/572http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/488/572https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/488/572https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/488/572http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/488/572GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/488/572/tablef1 (Derived inclination angles for the stars in the real sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/572/tablef1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/572/tablef1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/572/tablef1?GETtext/xml+votable180.050000true291.039049737.58479420.0055555555555555565/3646 3689 6/14579 14591 14733-14735 14751 14753-14754 14762-14765 14767-14768 14770 14774 14778 14780 14783 14825-14826 14915-14916 14918 14921 14923-14926 14928 14933 14938-14939 14947-14948 14955-14956 14958-14959 14974-14975 15057 15061 15105 15109 15111 15115 15121-15122 15126 15136 15140 15146 15151 15158 15168 15171https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/488/572?format=asciiOpticaldefaultJ/MNRAS/488/572/tablef1Derived inclination angles for the stars in the real sampleSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
