NGTS clusters survey V: Rotation in the Orion Star-forming Complex

Gareth D. Smith, Edward Gillen, Simon T. Hodgkin +16

We present a study of rotation across 30 square degrees of the Orion Star-forming Complex, following a 200 d photometric monitoring campaign by the Next Generation Transit Su…

NGTS clusters survey IV. Search for Dipper stars in the Orion Nebular Cluster

Tyler Moulton, Simon T Hodgkin, Gareth D Smith +13

The dipper is a novel class of young stellar object associated with large drops in flux on the order of 10 to 50 per cent lasting for hours to days. Too significant to arise from i…

A close-in puffy Neptune with hidden friends: The enigma of TOI 620

Michael A. Reefe, Rafael Luque, Eric Gaidos +82

We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…

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…

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…

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…

SALT observations of the Chromospheric Activity of Transiting Planet Hosts: Mass Loss and Star Planet Interactions

D. Staab, C. A. Haswell, Gareth D. Smith +4

We measured the chromospheric activity of the four hot Jupiter hosts WASP-43, WASP-51/HAT-P-30, WASP-72 & WASP-103 to search for anomalous values caused by the close-in companions.…
