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…
NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit
Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53
We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

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-…
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-EB-8: A double-lined eclipsing M+M binary discovered by citizen scientists
Sean M. O'Brien, Megan E. Schwamb, Christopher A. Watson +54
We report the identification and characterization of a new binary system composed of two near-equal mass M-dwarfs. The binary NGTS-EB-8 was identified as a planet candidate in data…
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 TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +123
We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey. VI: Confirmation of a Long-Period Giant Planet Discovered with a Single TESS Transit
Zahra Essack, Diana Dragomir, Paul A. Dalba +81
We report the discovery and confirmation of TOI-4465 b, a , giant planet orbiting a G dwarf star at 122 pc. The planet was…
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…
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
