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…

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…

Exploring the Neptunian Desert: Insights from a Homogeneous Planetary Sample

Lauren Doyle, David J. Armstrong, Lorena Acuña +26

In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, we compile a sample of TESS-observed planets using a ranking criterion which takes into ac…

NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary

Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35

Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…

NGTS-33b: A Young Super-Jupiter Hosted by a Fast Rotating Massive Hot Star

Douglas R. Alves, James S. Jenkins, Jose I. Vines +22

In the last few decades planet search surveys have been focusing on solar type stars, and only recently the high-mass regimes. This is mostly due to challenges arising from the lac…

TOI-2490b- The most eccentric brown dwarf transiting in the brown dwarf desert

Beth A. Henderson, Sarah L. Casewell, Andrés Jordán +40

We report the discovery of the most eccentric transiting brown dwarf in the brown dwarf desert, TOI02490b. The brown dwarf desert is the lack of brown dwarfs around main sequence s…

Photo-dynamical characterisation of the TOI-178 resonant chain

A. Leleu, J. -B. Delisle, L. Delrez +104

The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from 1.2 to 2.9 earth radius and orbital…
