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…
WASP-South detection of HD219666b transits provides an accurate ephemeris
C. Hellier, D. R. Anderson, S. Gill +1
The hot-Neptune HD219666b (= TOI-118.01) was an early discovery from Sector 1 of the TESS transit survey. Being a rare "Neptune desert" planet, and transiting a bright, V = 9.9 sta…
NGTS and WASP photometric recovery of a single-transit candidate from TESS
Samuel Gill, Daniel Bayliss, Benjamin F. Cooke +25
The Transiting Exoplanet Survey Satellite (\tess) produces a large number of single-transit event candidates, since the mission monitors most stars for only 27\,days. Such ca…
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…
Classifying Exoplanet Candidates with Convolutional Neural Networks: Application to the Next Generation Transit Survey
Alexander Chaushev, Liam Raynard, Michael R. Goad +13
Vetting of exoplanet candidates in transit surveys is a manual process, which suffers from a large number of false positives and a lack of consistency. Previous work has shown that…
Transit timing variations in the WASP-4 planetary system
John Southworth, M. Dominik, U. G. Jorgensen +25
Transits in the planetary system WASP-4 were recently found to occur 80s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that…
NGTS-7Ab: An ultra-short period brown dwarf transiting a tidally-locked and active M dwarf
James A. G. Jackman, Peter J. Wheatley, Dan Bayliss +36
We present the discovery of NGTS-7Ab, a high mass brown dwarf transiting an M dwarf with a period of 16.2 hours, discovered as part of the Next Generation Transit Survey (NGTS). Th…
The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey
S. Gill, P. F. L. Maxted, J. A. Evans +27
Some M-dwarfs around F-/G-type stars have been measured to be hotter and larger than predicted by stellar evolution models. Inconsistencies between observations and models need add…
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…
The EBLM Project V. Physical properties of ten fully convective, very-low-mass stars
Alexander von Boetticher, Amaury H. M. J. Triaud, Didier Queloz +28
Measurements of the physical properties of stars at the lower end of the main sequence are scarce. In this context we report masses, radii and surface gravities of ten very-low-mas…
