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…
TOI-3862 b: A dense super-Neptune deep in the hot Neptune desert
Ilaria Carleo, Amadeo Castro-González, Enric Pallé +61
The structure and evolution of close-in exoplanets are shaped by atmospheric loss and migration processes, which give rise to key population features such as the hot Neptune desert…
A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP
Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53
Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…
Precise mass and radius determination for two new and one known Neptune-sized planets around G Dwarf hosts
Ilaria Carleo, Grzegorz Nowak, Felipe Murgas +56
As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo…
TOI-333b: A Neptune Desert planet around a F7V star
Douglas R. Alves, James S. Jenkins, José I. Vinés +29
Observations have shown that planets similar to Neptune are rarely found orbiting Sun-like stars with periods up to ~4 days, defining the so-called Neptune desert region. Therefore…
