Confronting compositional confusion through the characterisation of the sub-Neptune orbiting HD 77946
L. Palethorpe, A. Anna John, A. Mortier +29
We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 ( = 1.17 M, = 1.31 R) star, which hosts a transiting p…
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…
An unusually low density ultra-short period super-Earth and three mini-Neptunes around the old star TOI-561
G. Lacedelli, L. Malavolta, L. Borsato +38
Based on HARPS-N radial velocities (RVs) and TESS photometry, we present a full characterisation of the planetary system orbiting the late G dwarf TOI-561. After the identification…
An ultra-short period rocky super-Earth orbiting the G2-star HD 80653
G. Frustagli, E. Poretti, T. Milbourne +26
Ultra-short period (USP) planets are a class of exoplanets with periods shorter than one day. The origin of this sub-population of planets is still unclear, with different formatio…
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…
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…
