We report the discovery of a system of two super-Earths orbiting the moderately active K-dwarf HD 176986 .
This work is part of the RoPES RV program of G- and K-type stars , which combines radial velocities ( RVs ) from the HARPS and HARPS-N spectrographs to search for short-period terrestrial planets .
HD 176986 b and c are super-Earth planets with masses of 5.74 and 9.18 M _ { \oplus } , orbital periods of 6.49 and 16.82 days , and distances of 0.063 and 0.119 AU in orbits that are consistent with circular .
The host star is a K2.5 dwarf , and despite its modest level of chromospheric activity ( log _ { 10 } ( R _ { HK } ^ { { } ^ { \prime } } ) = – 4.90 \pm 0.04 ) , it shows a complex activity pattern .
Along with the discovery of the planets , we study the magnetic cycle and rotation of the star .
HD 176986 proves to be suitable for testing the available RV analysis technique and further our understanding of stellar activity .
