The RoPES project with HARPS and HARPS-N III. Two candidate planets orbiting the G-type star HD 161098
N. Nari, A. Suárez Mascareño, J. I. González Hernández +9
Context. The development of refined instruments and techniques for a detailed analysis of the radial velocities (RVs) of stars other than the Sun allows the presence of planetary s…
The RoPES project with HARPS and HARPS-N II. A third planet in the multi-planet system HD 176986
N. Nari, A. Suárez Mascareño, J. I. González Hernández +7
Earth-like planets orbiting in the habitable zone of K- to G-type stars create an RV effect in amplitude of less than 1 \si{\meter\per\second} and have orbital periods of hundreds…
Stellar-activity analysis of the nearby M dwarf GJ 526. Multi-dimensional Gaussian-process modelling of RV, FWHM and S-index
A. K. Stefanov, J. I. González Hernández, A. Suárez Mascareño +17
M dwarfs are the most abundant stars in the Galaxy, and their low masses make them natural favourites for exoplanet radial-velocity (RV) searches. Nevertheless, these stars often d…
A second low-mass planet orbiting the nearby M-dwarf GJ 536
A. Suárez Mascareño, C. del Burgo, J. -B. Delisle +7
GJ 536 is a low-mass star, located 10 pc away from the Sun, that hosts a low-mass planet orbiting with a period of 8.71 days. Based on an analysis of the radial velocity (RV) time…
