DMPP-4: Candidate sub-Neptune mass planets orbiting a naked-eye star
J. R. Barnes, M. R. Standing, C. A. Haswell +9
We present radial velocity measurements of the very bright () nearby F star, DMPP-4 (HD 184960). The anomalously low Ca II H&K emission suggests mass loss from planets or…
A dense mini-Neptune orbiting the bright young star HD 18599
Jose I. Vines, James S. Jenkins, Zaira Berdiñas +23
Very little is known about the young planet population because the detection of small planets orbiting young stars is obscured by the effects of stellar activity and fast rotation…

We report the detection of a transiting, dense Neptune planet candidate orbiting the bright () K0.5V star HD 95338. Detection of the 55-day periodic signal comes from the an…
An ablating super-Earth in an eccentric binary from the Dispersed Matter Planet Project
John R. Barnes, Carole A. Haswell, Daniel Staab +8
Earth mass exoplanets are difficult to detect. The Dispersed Matter Planet Project (DMPP) identifies stars which are likely to host the most detectable low mass exoplanets. The sta…
A compact multi-planet system around a bright nearby star from the Dispersed Matter Planet Project
D. Staab, C. A. Haswell, J. R. Barnes +7
The Dispersed Matter Planet Project targets stars with anomalously low Ca II H&K chromospheric emission. High precision, high cadence radial velocity measurements of the F8V star H…
TOI-132 b: A short-period planet in the Neptune desert transiting a G-type star
Matías R. Díaz, James S. Jenkins, Davide Gandolfi +45
The Neptune desert is a feature seen in the radius-mass-period plane, whereby a notable dearth of short period, Neptune-like planets is found. Here we report the {\it TESS} discove…
NGTS-8b and NGTS-9b: two non-inflated hot-Jupiters
