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…
An old warm Jupiter orbiting the metal-poor G-dwarf TOI-5542
Nolan Grieves, François Bouchy, Solène Ulmer-Moll +31
We report the discovery of a 1.32 planet orbiting on a 75.12 day period around the G3V Gyr old star TOI-5542 (TIC 4662…
A transit timing variation observed for the long-period extremely low density exoplanet HIP 41378f
Edward M. Bryant, Daniel Bayliss, Alexandre Santerne +47
HIP 41378 f is a temperate planet with period of 542.08 days and an extremely low density of g cm. It transits the bright star HIP 41378…
NGTS 15b, 16b, 17b and 18b: four hot Jupiters from the Next Generation Transit Survey
Rosanna H. Tilbrook, Matthew R. Burleigh, Jean C. Costes +36
We report the discovery of four new hot Jupiters with the Next Generation Transit Survey (NGTS). NGTS-15b, NGTS-16b, NGTS-17b, and NGTS-18b are short-period (d) planets orbiti…
NGTS-14Ab: a Neptune-sized transiting planet in the desert
A. M. S. Smith, J. S. Acton, D. R. Anderson +35
Context: The sub-Jovian or Neptunian desert is a previously-identified region of parameter space where there is a relative dearth of intermediate-mass planets at short orbital peri…
NGTS-12b: A sub-Saturn mass transiting exoplanet in a 7.53 day orbit
Edward M. Bryant, Daniel Bayliss, Louise D. Nielsen +35
We report the discovery of the transiting exoplanet NGTS-12b by the Next Generation Transit Survey (NGTS). The host star, NGTS-12, is a V=12.38 mag star with an effective temperatu…
NGTS-11 b / TOI-1847 b: A transiting warm Saturn recovered from a TESS single-transit event
Samuel Gill, Peter J. Wheatley, Benjamin F. Cooke +37
We report the discovery of NGTS-11 b (=TOI-1847 b), a transiting Saturn in a 35.46-day orbit around a mid K-type star (Teff=5050 K). We initially identified the system from a singl…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
Three Short Period Jupiters from TESS
L. D. Nielsen, R. Brahm, F. Bouchy +74
We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is…
TOI-222: a single-transit TESS candidate revealed to be a 34-day eclipsing binary with CORALIE, EulerCam and NGTS
Monika Lendl, François Bouchy, Samuel Gill +58
We report the period, eccentricity, and mass determination for the TESS single-transit event candidate TOI-222, which displayed a single 3000 ppm transit in the TESS two-minute cad…
NGTS-10b: The shortest period hot Jupiter yet discovered
James McCormac, Edward Gillen, James A. G. Jackman +44
We report the discovery of a new ultra-short period transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of $2.162\,^{+0.092}_{-0.1…
NGTS-6b: An Ultra Short Period Hot-Jupiter Orbiting an Old K Dwarf
Jose I. Vines, James S. Jenkins, Jack S. Acton +37
