NGTS clusters survey - VI: Stellar rotation in seven young open clusters within the PLATO LOPS2 field

Alexander Hughes, Edward Gillen, Matthew Battley +18

We present NGTS measurements of rotation period distributions for FGKM stars in seven young open clusters spanning ~40--700 Myr within PLATO's first long-stare LOPS2 field. We meas…

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…

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-…

Mass estimates of the young TOI-451 transiting planets: Multidimensional Gaussian Process on stellar spectroscopic and photometric signals

Oscar Barragán, Manuel Mallorquín, Jorge Fernández-Fernández +30

The young TOI-451 planetary system, aged 125 Myr, provides a unique opportunity to test theories of planetary internal structures and atmospheric mass loss through examination of i…

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…

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…

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…

HD 35843: A Sun-like star hosting a long period sub-Neptune and inner super-Earth

Katharine Hesse, Ismael Mireles, François Bouchy +52

We report the discovery and confirmation of two planets orbiting the metal-poor Sun-like star, HD 35843 (TOI 4189). HD 35843 c is a temperate sub-Neptune transiting planet with an…

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…

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…

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…

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…

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…

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067

R. Luque, H. P. Osborn, A. Leleu +149

Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…

TESS Duotransit Candidates from the Southern Ecliptic Hemisphere

Faith Hawthorn, Sam Gill, Daniel Bayliss +20

Discovering transiting exoplanets with long orbital periods allows us to study warm and cool planetary systems with temperatures similar to the planets in our own Solar system. The…
