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…

Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations

J. Maldonado, D. F. Phillips, X. Dumusque +29

(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…

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…

Three years of Sun-as-a-star radial-velocity observations on the approach to solar minimum

A. Collier Cameron, A. Mortier, D. Phillips +33

The time-variable velocity fields of solar-type stars limit the precision of radial-velocity determinations of their planets' masses, obstructing detection of Earth twins. Since 20…

HARPS-N Solar Radial-Velocity Variations Are Dominated By Large, Bright Magnetic Regions

T. W. Milbourne, R. D. Haywood, D. F. Phillips +37

State of the art radial-velocity (RV) exoplanet searches are currently limited by RV signals arising from stellar magnetic activity. We analyze solar observations acquired over a 3…
