Abstract (from CDS):

We report the detection of 18 Jovian planets discovered as part of our Doppler survey of subgiant stars at Keck Observatory, with follow-up Doppler and photometric observations made at McDonald and Fairborn Observatories, respectively. The host stars have masses 0.927 ≤ M{sstarf}/M ≤ 1.95, radii 2.5 ≤ R{sstarf}/R≤ 8.7, and metallicities -0.46 ≤ [Fe/H] ≤ +0.30. The planets have minimum masses 0.9 MJup ≤ MP sin i ≲ 13 MJupand semimajor axes a ≥ 0.76 AU. These detections represent a 50% increase in the number of planets known to orbit stars more massive than 1.5 M and provide valuable additional information about the properties of planets around stars more massive than the Sun.
