Description

DMPP is a radial-velocity survey that aims to detect planets around stars exhibiting anomalous activity signatures, consistent with the presence of close-in evaporating planets. I present the discovery of 7 new planetary signals in 5 different systems: DMPP-2 c & d, DMPP-6 b & c, DMPP-7 b, DMPP-8 b, and DMPP-9 b. We derive detection limits for all 24 targets in our sample with adequate observational coverage, and test the DMPP hypothesis by calculating the occurrence rates for planets in this configuration.
