-1 to be investigated. Long-term RV surveys allow the detection of Earth-like and super-Earth-like planets in the habitable zones of Sun-like stars, prime targets for future missions for the atmospheric characterization of exoplanets. We present the analysis of the nearby G8, V-type star HD 161098 (V = 7. 68, mag, d =, 29. 75 pc). We searched for terrestrial planets in the habitable zone. We combined historical datasets with new data collected in an ongoing blind search program with HARPS, HARPS-N, and ESPRESSO. We utilized recently developed tools to extract RVs and to deal with the analysis of stellar activity. We performed a joint analysis of RVs and activity indicators to separate the planetary signals from those related to activity. -1 signals that we claim as candidate planets. We are not able to confirm their nature with certainty. Candidate HD 161098 b has an orbital period of 72. 578_ -0. 060 ^ +0. 059, and a minimum mass of 3. 63 ± 0. 59, M_⊕. HD 161098 c has an orbital period of 682. 5_ -9. 9 ^ +9. 5, and a minimum mass of 7. 8_ -1. 4 ^ +1. 5, M_⊕. If confirmed, candidate HD 161098 c would reside in the optimistic habitable zone of the star. We find a magnetic cycle of 4090_ -130 ^ +140, period and a rotation period of 28. 22_ -0. 35 ^ +0. 30,. Our analysis sets the stage for future observing campaigns of the star, finalized for the confirmation of our results. -1 era at long orbital periods with a combination of stellar activity treatment and long-term campaigns.
