Bow-shocks, nova shells, disc winds and tilted discs: The Nova-Like V341 Ara Has It All
N. Castro Segura, C. Knigge, J. A. Acosta-Pulido +21
V341 Ara was recently recognised as one of the closest (d ~ 150 pc) and brightest (V~ 10) nova-like cataclysmic variables. This unique system is surrounded by a bright emission neb…
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…
WD1032+011, an inflated brown dwarf in an old eclipsing binary with a white dwarf
S. L. Casewell, C. Belardi, S. G. Parsons +11
We present the discovery of only the third brown dwarf known to eclipse a non-accreting white dwarf. Gaia parallax information and multi-colour photometry confirm that the white dw…
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…
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…
The DECam Minute Cadence Survey II: 49 Variables but No Planetary Transits of a White Dwarf
Kyra Dame, Claudia Belardi, Mukremin Kilic +4
We present minute cadence photometry of 31732 point sources observed in one 3 DECam pointing centred at RA = 09:03:02 and Dec = -04:35:00 over eight consecutive half-nigh…
Multi-wavelength observations of the EUV variable metal-rich white dwarf GD 394
David J. Wilson, Boris T. Gaensicke, Detlev Koester +13
We present new Hubble Space Telescope (HST) ultraviolet and ground-based optical observations of the hot, metal-rich white dwarf GD 394. Extreme-ultraviolet (EUV) observations in 1…
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…
The first sub-70 minute non-interacting WD-BD system: EPIC212235321
S. L. Casewell, I. P. Braker, S. G. Parsons +9
We present the discovery of the shortest-period, non-interacting, white dwarf-brown dwarf post-common-envelope binary known. The K2 light curve shows the system, EPIC 21223532 has…
The DECam Minute Cadence Survey I
Claudia Belardi, Mukremin Kilic, Jeffrey A. Munn +4
We present the first results from a minute cadence survey of a three square degree field obtained with the Dark Energy Camera. We imaged part of the Canada-France-Hawaii Telescope…
