A spectrum of the system will contain a reflected light component which varies in amplitude and Doppler shift as the planet orbits the star. Assuming the secondary spectrum is primarily the reflected stellar spectrum, we can limit the relative reflected light flux to be less than 5 x 10(-5). This implies an upper limit of 0.3 for the planetary geometric albedo near 480 nm, assuming a planetary radius of 1.2 R-Jup. This albedo is significantly less than that of any of the giant planets of the solar system and is not consistent with certain published theoretical predictions. dc.language.iso en_US dc.publisher American Astronomical Society dash.license LAA dc.title An Upper Limit on the Reflected Light from the Planet Orbiting the Star τ Bootis dc.type Journal Article dc.description.version Version of Record dc.relation.journal The Astrophysical Journal dash.depositing.author Charbonneau, David::a0e3ca75d3fb8511f2f554ed69428108::600 dc.date.available 2019-09-24T17:25:25Z dash.workflow.comments 1Science Serial ID 95525 dc.identifier.doi 10.1086/312234 dash.source.volume 522;2 dash.source.page L145-L148
