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…

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…

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

S. Ulmer-Moll, S. Gill, R. Brahm +64

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…

The SPACE Program. I. The featureless spectrum of HD 86226 c challenges sub-Neptune atmosphere trends

K. Angelique Kahle, Jasmina Blecic, Reza Ashtari +26

Sub-Neptune exoplanets are the most abundant type of planet known today. As they do not have a Solar System counterpart, many open questions exist about their composition and forma…

X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library

Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29

The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…

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…

A closer look at LTT 9779b: The ESPRESSO endeavour to pierce the atmospheric veil

R. Ramírez Reyes, James S. Jenkins, Elyar Sedaghati +9

The proliferation of exoplanet discoveries in exotic environments like the Neptune desert challenges our understanding of planetary atmospheres under intense irradiation. The unexp…

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…
