The return of the spin period in DW Cnc and evidence of new high state outbursts
C. Duffy, G. Ramsay, D. Steeghs +16
DW Cnc is an intermediate polar which has previously been observed in both high and low states. Observations of the high state of DW Cnc have previously revealed a spin period at ~…
Scintillation-limited photometry with the 20-cm NGTS telescopes at Paranal Observatory
Sean M. O'Brien, Daniel Bayliss, James Osborn +17
Ground-based photometry of bright stars is expected to be limited by atmospheric scintillation, although in practice observations are often limited by other sources of systematic n…
The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf
O. Barragán, D. J. Armstrong, D. Gandolfi +103
We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…
NGTS clusters survey -- III: A low-mass eclipsing binary in the Blanco 1 open cluster spanning the fully convective boundary
Gareth D. Smith, Edward Gillen, Didier Queloz +27
We present the discovery and characterisation of an eclipsing binary identified by the Next Generation Transit Survey in the 115 Myr old Blanco 1 open cluster. NGTS J0002-29…
TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet
Ares Osborn, David J. Armstrong, Bryson Cale +125
We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…
NGTS-19b : A high mass transiting brown dwarf in a 17-day eccentric orbit
Jack S. Acton, Michael R. Goad, Matthew R. Burleigh +34
We present the discovery of NGTS-19b, a high mass transiting brown dwarf discovered by the Next Generation Transit Survey (NGTS). We investigate the system using follow up photomet…
A transit timing variation observed for the long-period extremely low density exoplanet HIP 41378f
Edward M. Bryant, Daniel Bayliss, Alexandre Santerne +47
HIP 41378 f is a temperate planet with period of 542.08 days and an extremely low density of g cm. It transits the bright star HIP 41378…
Stellar flares detected with the Next Generation Transit Survey
James A. G. Jackman, Peter J. Wheatley, Jack S. Acton +19
We present the results of a search for stellar flares in the first data release from the Next Generation Transit Survey (NGTS). We have found 610 flares from 339 stars, with spectr…
NGTS 15b, 16b, 17b and 18b: four hot Jupiters from the Next Generation Transit Survey
Rosanna H. Tilbrook, Matthew R. Burleigh, Jean C. Costes +36
We report the discovery of four new hot Jupiters with the Next Generation Transit Survey (NGTS). NGTS-15b, NGTS-16b, NGTS-17b, and NGTS-18b are short-period (d) planets orbiti…
Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
NGTS-13b: A hot 4.8 Jupiter-mass planet transiting a subgiant star
Nolan Grieves, Louise D. Nielsen, Jose I. Vines +31
We report the discovery of the massive hot Jupiter NGTS-13b by the Next Generation Transit Survey (NGTS). The V = 12.7 host star is likely in the subgiant evolutionary phase with l…
NGTS-14Ab: a Neptune-sized transiting planet in the desert
A. M. S. Smith, J. S. Acton, D. R. Anderson +35
Context: The sub-Jovian or Neptunian desert is a previously-identified region of parameter space where there is a relative dearth of intermediate-mass planets at short orbital peri…
