Gaia's revolution in stellar variability
L. Eyer, L. Rimoldini, L. Rohrbasser +15
Stellar variability studies are now reaching a completely new level thanks to ESA's Gaia mission, which enables us to locate many variable stars in the Hertzsprung-Russell diagram…
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-8b and NGTS-9b: two non-inflated hot-Jupiters
Jean C. Costes, Christopher A. Watson, Claudia Belardi +35
We report the discovery, by the Next Generation Transit Survey (NGTS), of two hot-Jupiters NGTS-8b and NGTS-9b. These orbit a V = 13.68 K0V star (Teff = 5241 +/- 50 K) with a perio…
NGTS-10b: The shortest period hot Jupiter yet discovered
James McCormac, Edward Gillen, James A. G. Jackman +44
We report the discovery of a new ultra-short period transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of $2.162\,^{+0.092}_{-0.1…
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…
Identification of Young Stellar Object candidates in the DR2 x AllWISE catalogue with machine learning methods
G. Marton, P. Ábrahám, E. Szegedi-Elek +8
The second Data Release (DR2) contains astrometric and photometric data for more than 1.6 billion objects with mean magnitude 20.7, including many Young Stella…
