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…
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…
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…
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 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…
NGTS-7Ab: An ultra-short period brown dwarf transiting a tidally-locked and active M dwarf
James A. G. Jackman, Peter J. Wheatley, Dan Bayliss +36
We present the discovery of NGTS-7Ab, a high mass brown dwarf transiting an M dwarf with a period of 16.2 hours, discovered as part of the Next Generation Transit Survey (NGTS). Th…
A low-mass eclipsing binary within the fully convective zone from the NGTS
S. L. Casewell, L. Raynard, C. A. Watson +22
We have discovered a new, near-equal mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of 3 field age ( 1 Gyr), late M dwarf eclips…
Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC03
Julio A. Carballo-Bello, S. Ramirez Alegria, J. Borissova +12
We present deep near-infrared photometry and spectroscopy of the globular cluster 2MASS-GC03 projected in the Galactic disk using MMIRS on the Clay telescope (Las Campanas Observat…
On the Crucial Cluster Andrews-Lindsay 1 and a 4% Distance Solution for its PN
D. Majaess, G. Carraro, C. Moni Bidin +5
Andrews-Lindsay 1 is a pertinent open cluster granted it may host the planetary nebula PHR 1315-6555, yet ambiguities linger concerning its fundamental parameters (>50% scatter). N…
