Abstract

GJ 1061 is a very nearby M star hosting three low-mass temperate planets detected from radial velocity variations. The close to 4:2:1 period commensurability of the planets, the available long-term monitoring of the system, and new very-high-precision radial velocity measurements from ESPRESSO enable the determination of masses from the planet-planet interaction. Using nested sampling we derived parameter distributions for a co-planar configuration. The three planets (M_b=1.07 ± 0.11 M, P_b=3.2073 ± 0.0003 d; M_c=1.76 ± 0.13 M, P_c=6.6821 ± 0.0008 d; and M_d=1.55 ± 0.17M, P_d=13.066 ± 0.002 d) are potentially all rocky with equilibrium temperatures between 360 and 240 K. This makes the GJ 1061 system one of the prime targets for future ground- or space-based instruments suitable for a direct detection of the planetary atmospheres.
