(Oxford University Press, 2020)We present the discovery of NGTS J0930-18, an extreme mass ratio eclipsing M-dwarf binary system with an early Mdwarf primary and a late M-dwarf secondary close to the hydrogen burning limit. Global modelling of photometry ...
-
(Nature, 2020)About 1 out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultrashort-period planet(1,2). All of the previously known ultrashort-period planets are either hot Jupiters, with sizes above ...
-
(Oxford university press, 2017)The Next Generation Transit Survey (NGTS), operating in Paranal since 2016, is a wide-field survey to detect Neptunes and super-Earths transiting bright stars, which are suitable for precise radial velocity follow-up and ...
-
(Oxford University Press, 2019)We present the detection of an energetic flare on the pre-main-sequence M3 star NGTS J121939.5–355557, which we estimate to be only 2 Myr old. The flare had an energy of 3.2 ±0 0 4 3 ×1036 erg and a fractional amplitude ...
-
(Oxford University Press, 2020)We present the detection of high-energy white-light flares from pre-main-sequence stars associated with the Orion Complex, observed as part of the Next Generation Transit Survey (NGTS). With energies up to 5.2 x 10(35) erg ...
-
(Oxford Unv Press, 2020)We determine rotation periods for 127 stars in the similar to 115-Myr-old Blanco 1 open cluster using similar to 200 d of photometric monitoring with the Next Generation Transit Survey. These stars span F5-M3 spectral types ...
-
(Oxford University Press, 2020)We report the discovery of a new ultrashort period (USP) transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of 2.162(-0.107)(+0.092) M-J and 1.205(-0.083)(+0.117) R-J and ...
-
(IOP Publishing, 2020)We report the discovery of NGTS-11 b (=TOI-1847b), a transiting Saturn in a 35.46 day orbit around a mid K-type star (T-eff = 5050 +/- 80 K). We initially identified the system from a single-transit event in a TESS full-frame ...
-
(Oxford University Press, 2020)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 temperature of T-eff = 5690 +/- 130 K. NGTS-12b ...
-
(Oxford University Press, 2018)We present the discovery of NGTS-1b, a hot Jupiter transiting an early M-dwarf host (T-eff,(*) = 3916 (+71)(-63) K) in a P = 2.647 d orbit discovered as part of the Next Generation Transit Survey (NGTS). The planet has a ...
-
(Oxford University Press, 2019)We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34 d orbit. NGTS-4b has a mass M = 20.6 ± 3.0M⊕ and radius R = 3.18 ± 0.26 R⊕, which places it well within the ...
-
(Oxford Unv Press, 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 (T-eff = 5241 +/- 50 K) with a period of 2.49970 d, and a V = 12.80 F8V star ...
-
(Oxford Unv Press, 2020)We report the period, eccentricity, and mass determination for the Transiting Exoplanet Survey Satellite (TESS) single-transit event candidate TOI-222, which displayed a single 3000 ppm transit in the TESS 2-min cadence ...
-
(Oxford University Press, 2018)We present the discovery of NGTS-3Ab, a hot Jupiter found transiting the primary star of an unresolved binary system. We develop a joint analysis of multi-colour photometry, centroids, radial velocity (RV) cross-correlation ...
