Periodic stellar variability from almost a million NGTS light curves
Joshua T. Briegal, Edward Gillen, Didier Queloz +25
We analyse 829,481 stars from the Next Generation Transit Survey (NGTS) to extract variability periods. We utilise a generalisation of the autocorrelation function (the G-ACF), whi…
TIC-320687387 B: a long-period eclipsing M-dwarf close to the hydrogen burning limit
Samuel Gill, Solene Ulmer-Moll, Peter J. Wheatley +26
We are using precise radial velocities from CORALIE together with precision photometry from the Next Generation Transit Survey (NGTS) to follow up stars with single-transit events…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
Ground-based detection of G star superflares with NGTS
James A. G. Jackman, Peter J. Wheatley, Chloe E. Pugh +19
We present high cadence detections of two superflares from a bright G8 star (V = 11.56) with the Next Generation Transit Survey (NGTS). We improve upon previous superflare detectio…
