Three new exoplanet systems from the Dispersed Matter Planet Project

J. R. Barnes, C. A. Haswell, Z. O. B. Ross +7

We present a radial velocity analysis of three bright, low-activity stars identified by the Dispersed Matter Planet Project (DMPP). We use a Bayesian framework to compare purely Ke…

The Dispersed Matter Planet Project Sample -- Detection limits, Occurrence Rates and New Planets

Matthew R. Standing, John R. Barnes, Carole A. Haswell +8

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. He…

HD 28471: a near-resonant compact multiplanet system with a possible cold giant planet

A. T. Stevenson, C. A. Haswell, J. R. Barnes +5

We present radial velocity measurements of the star HD 28471, observed by HARPS at the ESO 3.6 m telescope over a baseline of years. We have searched for planetary compani…

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 possible transit of a disintegrating exoplanet in the nearby multiplanet system DMPP-1

Mark H. Jones, Carole A. Haswell, John R. Barnes +2

We analyse TESS photometry of DMPP-1 (HD 38677; TIC 66560666), a nearby F8V star hosting hot super-Earth planets and a warm Neptune. Using the Transit Least Squares algorithm and o…

Dispersed Matter Planet Project Discoveries of Ablating Planets Orbiting Nearby Bright Stars

Carole A. Haswell, Daniel Staab, John R. Barnes +6

Some highly irradiated close-in exoplanets orbit stars showing anomalously low stellar chromospheric emission. We attribute this to absorption by circumstellar gas replenished by m…
