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…
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…
