Two young planetary systems around field stars with ages between 20-320 Myr from TESS
George Zhou, Samuel N. Quinn, Jonathan Irwin +46
Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages Myr from observa…
WASP-186 and WASP-187: two hot Jupiters discovered by SuperWASP and SOPHIE with additional observations by TESS
N. Schanche, G. Hébrard, A. Collier Cameron +15
We present the discovery of two new hot Jupiters identified from the WASP survey, WASP-186b and WASP-187b (TOI-1494.01 and TOI-1493.01). Their planetary nature was established from…
K2-111: an old system with two planets in near-resonance
A. Mortier, M. R. Zapatero Osorio, L. Malavolta +64
This paper reports on the detailed characterisation of the K2-111 planetary system with K2, WASP, and ASAS-SN photometry as well as high-resolution spectroscopic data from HARPS-N…
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…
NGTS-12b: A sub-Saturn mass transiting exoplanet in a 7.53 day orbit
Edward M. Bryant, Daniel Bayliss, Louise D. Nielsen +35
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 temperatu…
An eclipsing M-dwarf close to the hydrogen burning limit from NGTS
Jack S. Acton, Michael R. Goad, Sarah L. Casewell +20
We present the discovery of NGTS J0930-18, an extreme mass ratio eclipsing M-dwarf binary system with an early M-dwarf primary and a late M-dwarf secondary close to the hydrogen bu…
NGTS clusters survey -- II. White-light flares from the youngest stars in Orion
James A. G. Jackman, Peter J. Wheatley, Jack S. Acton +18
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 (N…
NGTS-11 b / TOI-1847 b: A transiting warm Saturn recovered from a TESS single-transit event
Samuel Gill, Peter J. Wheatley, Benjamin F. Cooke +37
We report the discovery of NGTS-11 b (=TOI-1847 b), a transiting Saturn in a 35.46-day orbit around a mid K-type star (Teff=5050 K). We initially identified the system from a singl…
Two transiting hot Jupiters from the WASP survey: WASP-150b and WASP-176b
Benjamin F. Cooke, Don Pollacco, Y. Almleaky +49
We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ( = 0.38) hot Jupiter on a 5.6 day orbit around a $…
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…
Discovery and characterization of the exoplanets WASP-148b and c. A transiting system with two interacting giant planets
G. Hebrard, R. F. Diaz, A. C. M. Correia +39
We present the discovery and characterization of WASP-148, a new extrasolar system that includes at least two giant planets. The host star is a slowly rotating inactive late-G dwar…
Searching for Electromagnetic Counterparts to Gravitational-wave Merger Events with the Prototype Gravitational-wave Optical Transient Observer (GOTO-4)
B. P. Gompertz, R. Cutter, D. Steeghs +49
We report the results of optical follow-up observations of 29 gravitational-wave triggers during the first half of the LIGO-Virgo Collaboration (LVC) O3 run with the Gravitational-…
NGTS J214358.5-380102 -- NGTS discovery of the most eccentric known eclipsing M-Dwarf binary system
Jack S. Acton, Michael R. Goad, Liam Raynard +23
We present the discovery of NGTS J214358.5-380102, an eccentric M-dwarf binary discovered by the Next Generation Transit Survey. The system period of 7.618 days is greater than man…
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…
