cds-question@unistra.frsolar-system-planetsradio-continuum-emissionsurveysWe present a targeted search for narrow-band (<5Hz) drifting sinusoidal radio emission from 86 stars in the Kepler field hosting confirmed or candidate exoplanets. Radio emission less than 5Hz in spectral extent is currently known to only arise from artificial sources. The stars searched were chosen based on the properties of their putative exoplanets, including stars hosting candidates with 380K>T_eq_>230K, stars with five or more detected candidates or stars with a super-Earth (R_p_<3R_{earth}_) in a >50 day orbit. Baseband voltage data across the entire band between 1.1 and 1.9GHz were recorded at the Robert C. Byrd Green Bank Telescope between 2011 February and April and subsequently searched offline. No signals of extraterrestrial origin were found. We estimate that fewer than ~1% of transiting exoplanet systems host technological civilizations that are radio loud in narrow-band emission between 1 and 2GHz at an equivalent isotropically radiated power (EIRP) of ~1.5x10^21^erg/s, approximately eight times the peak EIRP of the Arecibo Planetary Radar, and we limit the number of 1-2GHz narrow-band-radio-loud Kardashev type II civilizations in the Milky Way to be <10^-6^/M_{sun}_. Here we describe our observations, data reduction procedures and results.2013ApJ...767...94Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/767/94CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/562/A108 : 150MHz emission from exoplanets (Sirothia+, 2014)J/ApJ/736/19 : Kepler planetary candidates.
