TL;DR
This paper presents new high-precision Doppler observations of GJ1046, updates its orbital parameters, and estimates its stellar mass, aiming to refine the system's characterization and resolve the inclination degeneracy with future Gaia data.
Contribution
The study provides new Doppler data, a revised stellar mass estimate, and updated orbital parameters for GJ1046, enhancing understanding of this system.
Findings
New Doppler data from HARPS and FEROS
Updated orbital parameters of GJ1046
Revised stellar mass estimate
Abstract
In this paper we present new precise Doppler data of GJ1046 taken between November 2005 and July 2018 with the HARPS and the FEROS high-resolution spectographs. In addition, we provide a new stellar mass estimate of GJ1046 and we update the orbital parameters of the GJ1046 system. These new data and analysis could be used together with the GAIA epoch astrometry, when available, for braking the degeneracy and revealing the true mass of the GJ1046 system.
