VizieR Online Data Catalog: HARPS-N radial velocities of an USP planet (Malavolta+, 2018)
VizieR Online Data Catalog(2018)
摘要
We collected 44 spectra using HARPS-N at the Telescopio Nazionale Galileo (TNG), in La Palma (Cosentino et al. 2012SPIE. 8446E.. 1VC), with the goal of precisely determining the mass of the USP planet. To reach this goal, we followed a twofold strategy: we gathered at least two points each night (when weather allowed) in order to remove activity variations by applying nightly offsets (eg, Hatzes et al. 2011ApJ... 743... 75H; Pepe et al. 2013Natur. 503.. 377P), and we observed the target for a duration of a few stellar rotations to be able to use a Gaussian process (GP) regression (eg, Haywood et al. 2014MNRAS. 443.2517 H; Rajpaul et al. 2015MNRAS. 452.2269 R) to model the stellar activity signals directly.
