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…
