Following up the Kepler field with PLATO: Transit Timing Performance
Morgan A. Mitchell, James McCormac, Don Pollacco +11
The European Space Agency is set to launch PLATO, the third medium-class mission of its Cosmic Vision programme, in early 2027. Using the transit method, PLATO is expected to detec…
The Neptunian ridge planet WASP-156 b does not have a polar orbit
M. Lafarga, J. I. Espinoza-Retamal, H. M. Cegla +26
The population of short-period exo-Neptunes is thought to be shaped by an interplay between different dynamical mechanisms, such as orbital migration and tidal effects, and photoev…
Assessment of PLATO Science Performance
Juan Cabrera, Heike Rauer, Reza Samadi +121
The PLATO mission is scheduled for launch early 2027. In this paper we present an overview of the performance drivers for the mission at the time where all flight models of the cam…
TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter
Toby Rodel, Solène Ulmer-Moll, Samuel Gill +63
We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of R and a mass of M on a long-…
Demographics of Close-In TESS Exoplanets Orbiting FGK Main-sequence Stars
Kaiming Cui, David J. Armstrong, Andreas Hadjigeorghiou +5
Understanding the demographics of close-in planets is crucial for insights into exoplanet formation and evolution. We present a detailed analysis of occurrence rates for close-in (…
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…
Resolving star spots on WASP-85 A using high-resolution transit spectroscopy
Vedad Kunovac, Heather Cegla, Hritam Chakraborty +23
Stellar surface inhomogeneities such as spots and faculae introduce Doppler variations that challenge exoplanet detection via the radial velocity method. While their impact on disc…
RAVEN: RAnking and Validation of ExoplaNets
Andreas Hadjigeorghiou, David J. Armstrong, Kaiming Cui +5
We present RAVEN, a newly developed vetting and validation pipeline for TESS exoplanet candidates. The pipeline employs a Bayesian framework to derive the posterior probability of…
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…
Stellar X-ray variability and planetary evolution in the DS Tucanae system
George W. King, Lía R. Corrales, Vincent Bourrier +5
We present an analysis of four Chandra observations of the 45 Myr old DS Tuc binary system. We observed X-ray variability of both stars on timescales from hours to months, includin…
The First Spin-Orbit Obliquity of an M dwarf/brown dwarf System: An eccentric and aligned TOI-2119 b
Lauren Doyle, Caleb I. Cañas, Jessica E. Libby-Roberts +15
We report the first instance of an M dwarf/brown dwarf obliquity measurement for the TOI-2119 system using the Rossiter-McLaughlin effect. TOI-2119 b is a transiting brown dwarf or…
