The magnetically quiet solar surface dominates HARPS-N solar RVs during low activity

Ben S. Lakeland, Tim Naylor, Raphaëlle Haywood +15

Using images from the Helioseismic and Magnetic Imager aboard the \textit{Solar Dynamics Observatory} (SDO/HMI), we extract the radial-velocity (RV) signal arising from the suppres…

Two transiting hot Jupiters from the WASP survey: WASP-150b and WASP-176b

Benjamin F. Cooke, Don Pollacco, Y. Almleaky +49

We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ( = 0.38) hot Jupiter on a 5.6 day orbit around a $…

The spectral impact of magnetic activity on disk-integrated HARPS-N solar observations: exploring new activity indicators

A. P. G. Thompson, C. A. Watson, R. D. Haywood +21

Stellar activity is the major roadblock on the path to finding true Earth-analogue planets with the Doppler technique. Thus, identifying new indicators that better trace magnetic a…

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…

WASP-180Ab: Doppler tomography of an hot Jupiter orbiting the primary star in a visual binary

L. Y. Temple, C. Hellier, D. R. Anderson +26

We report the discovery and characterisation of WASP-180Ab, a hot Jupiter confirmed by the detection of its Doppler shadow and by measuring its mass using radial velocities. We fin…
