Retired A Stars and Their Companions VIII: 15 New Planetary Signals Around Subgiants and Transit Parameters for California Planet Search Planets with Subgiant Hosts
https://arxiv.org/abs/1811.03043

Quote :
We present the discovery of 7 new planets and 8 planet candidates around subgiant stars, as additions to the known sample of planets around "retired A stars" (Johnson et al. 2006). Among these are the possible first 3-planet systems around subgiant star, HD 163607 and HD 4917. Additionally, we present calculations of possible transit times, durations, depths, and probabilities for all known planets around subgiant (3 < log g < 4) stars, focused on possible transits during the TESS mission. While most have transit probabilities of 1-2%, we find that there are 3 planets with transit probabilities > 9%.

Just a heads-up. If you used version 1 of the paper for your personal notes, it includes a mp sin i = 1.6±0.19 MJ planet in a 534.5±8.9 day orbit around HD 10383. This planet is not listed in the final version of this paper. So if you're like me and you've got a planet in your notes around this star that you can't find evidence for in scientific literature, that's what's going on.

Follow-up: Similar problem with HD 16559 b.
