NGTS-8b and NGTS-9b: two non-inflated hot-Jupiters
, 2020 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 period of 2.49970 days, and a V = 12.80 F8V star (Teff = 6330

I. Spin–Orbit Measurements of Three Transiting Hot Jupiters: WASP-72b, WASP-100b, and WASP-109b
, 2018 We report measurements of the sky-projected spin-orbit angles for three transiting hot Jupiters, two of which are in nearly polar orbits, WASP-100b and WASP-109b, and a third in a low-obliquity orbit, WASP-72b. We obtained these measurements by observing Tinney, C. G., Addison, B. C., Wang, Songhu, Wright, D. J., Bayliss, D., Johnson, M.

, 2015 Many hot Jupiters (HJs) are detected by the Doppler and transit techniques. From surveys using these two techniques, however, the measured HJ occurrence rates differ by a factor of two or more.Wang, Ji, Huang, Xu, Horch, Elliott P., Fischer, Debra A. +3 morecore +1 more sourceWide Binary Orbits Are Preferentially Aligned with the Orbits of Small Planets, but Probably Not Hot Jupiters
The Astronomical JournalStudying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 au) can shed light on how planets form and evolve in binary systems.

The Astrophysical Journal LettersThe stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity.Xian-Yu Wang, Malena Rice, Songhu Wang, Shubham Kanodia, Fei Dai, Sarah E.
