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…
Radial velocity confirmation of K2-100b: a young, highly irradiated, and low density transiting hot Neptune
O. Barragán, S. Aigrain, D. Kubyshkina +37
We present a detailed analysis of HARPS-N radial velocity observations of K2-100, a young and active star in the Praesepe cluster, which hosts a transiting planet with a period of…
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…
Greening of the Brown Dwarf Desert. EPIC 212036875 b -- a 51 M object in a 5 day orbit around an F7 V star
Carina M. Persson, Szilárd Csizmadia, Alexander J. Mustill +55
Our aim is to investigate the nature and formation of brown dwarfs by adding a new well-characterised object to the small sample of less than 20 transiting brown dwarfs. One brown…
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…
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…
