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…
The discovery of three hot Jupiters, NGTS-23b, 24b and 25b, and updated parameters for HATS-54b from the Next Generation Transit Survey
David G. Jackson, Christopher A. Watson, Ernst J. W. de Mooij +35
We report the discovery of three new hot Jupiters with the Next Generation Transit Survey (NGTS) as well as updated parameters for HATS-54b, which was independently discovered by N…
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…
An Ultra-Hot Neptune in the Neptune desert
James S. Jenkins, Matías R. Díaz, Nicolás T. Kurtovic +81
About one out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultra-short-period planet (Sanchis-ojeda et al. 2014; Winn et al. 2018). All of the…
Simultaneous TESS and NGTS Transit Observations of WASP-166b
Edward M. Bryant, Daniel Bayliss, James McCormac +21
We observed a transit of WASP-166 b using nine NGTS telescopes simultaneously with TESS observations of the same transit. We achieved a photometric precision of 152 ppm per 30 minu…
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…
NGTS-8b and NGTS-9b: two non-inflated hot-Jupiters
Jean C. Costes, Christopher A. Watson, Claudia Belardi +35
We report the discovery, by the Next Generation Transit Survey (NGTS), of two hot-Jupiters NGTS-8b and NGTS-9b. These orbit a V = 13.68 K0V star (Teff = 5241 +/- 50 K) with a perio…
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-5b: a highly inflated planet offering insights into the sub-Jovian desert
Philipp Eigmüller, Alexander Chaushev, Edward Gillen +32
Context: Planetary population analysis gives us insight into formation and evolution processes. For short-period planets, the subJovian desert has been discussed in recent years wi…
NGTS-6b: An Ultra Short Period Hot-Jupiter Orbiting an Old K Dwarf
Jose I. Vines, James S. Jenkins, Jack S. Acton +37
We report the discovery of a new ultra-short period hot Jupiter from the Next Generation Transit Survey. NGTS-6b orbits its star with a period of 21.17~h, and has a mass and radius…
NGTS-4b: A sub-Neptune Transiting in the Desert
Richard G. West, Edward Gillen, Daniel Bayliss +48
We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34d orbit. NGTS-4b has a mass M=M_E and radius R=…
