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…
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…
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 ~…
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…
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…
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 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 long period (P = 61.8-d) M5V dwarf eclipsing a Sun-like star from TESS and NGTS
Samuel Gill, Benjamin F. Cooke, Daniel Bayliss +27
The Transiting Exoplanet Survey Satellite (TESS) has produced a large number of single transit event candidates which are being monitored by the Next Generation Transit Survey (NGT…
NGTS clusters survey. I. Rotation in the young benchmark open cluster Blanco 1
Edward Gillen, Joshua T. Briegal, Simon T. Hodgkin +18
We determine rotation periods for 127 stars in the ~115 Myr old Blanco 1 open cluster using ~200 days of photometric monitoring with the Next Generation Transit Survey (NGTS). Thes…
NGTS and WASP photometric recovery of a single-transit candidate from TESS
Samuel Gill, Daniel Bayliss, Benjamin F. Cooke +25
The Transiting Exoplanet Survey Satellite (\tess) produces a large number of single-transit event candidates, since the mission monitors most stars for only 27\,days. Such ca…
