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…
NGTS-11 c: a transiting Neptune-mass planet interior to the warm Saturn NGTS-11 b
David R. Anderson, Jose I. Vines, Katharine Hesse +56
We report the discovery of NGTS-11 c, a transiting warm Neptune ( d; ; ), in an…
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-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…
TOI-2447 b / NGTS-29 b: a 69-day Saturn around a Solar analogue
Samuel Gill, Daniel Bayliss, Solène Ulmer-Moll +63
Discovering transiting exoplanets with relatively long orbital periods (10 days) is crucial to facilitate the study of cool exoplanet atmospheres () and to u…
Planet Hunters NGTS: New Planet Candidates from a Citizen Science Search of the Next Generation Transit Survey Public Data
Sean M. O'Brien, Megan E. Schwamb, Samuel Gill +35
We present the results from the first two years of the Planet Hunters NGTS citizen science project, which searches for transiting planet candidates in data from the Next Generation…
NGTS-30 b/TOI-4862 b: An 1 Gyr old 98-day transiting warm Jupiter
M. P. Battley, K. A. Collins, S. Ulmer-Moll +63
Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of pl…
NGTS-28Ab: A short period transiting brown dwarf
Beth A. Henderson, Sarah L. Casewell, Michael R. Goad +43
We report the discovery of a brown dwarf orbiting a M1 host star. We first identified the brown dwarf within the Next Generation Transit Survey data, with supporting observations f…
Transit Timing Variations in the three-planet system: TOI-270
Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther +69
We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered…
A systematic validation of hot Neptunes in TESS data
Christian Magliano, Giovanni Covone, Richa Dobal +26
We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using DAVE and TRICERATOPS. We performed a systematic validation of 250 transit-…

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…
