Aims. We report the detection of long-period radial velocity (RV) variationsin three giant stars, HD 19615, HD 150010, and HD 174205, using precise RVmeasurements. Methods. These detections are part of the Search for Exoplanetsaround Northern Circumpolar Stars (SENS) survey being conducted at theBohyunsan Optical Astronomy Observatory (BOAO). The nature of the RV variationswas investigated by analyzing the photometric and line shape variations. Wefound no variability with the RV period in these quantities and conclude thatthe RV variations are most likely caused by planetary companions. Results.Orbital solutions for the three stars yield orbital periods of 402 d, 562 d,and 582 d and minimum masses of 8.5 MJ , 2.4 MJ , and 4.2 MJ , respectively.These masses and periods are typical for planets around intermediate-massstars, although some unclear interpretations and recent studies may beingcalling some planet convictions into question. Nevertheless, the SENS programis contributing to our knowledge of giant planets around intermediate-massstars.
