  Aims. We report the detection of long-period radial velocity (RV) variations
in three giant stars, HD 19615, HD 150010, and HD 174205, using precise RV
measurements. Methods. These detections are part of the Search for Exoplanets
around Northern Circumpolar Stars (SENS) survey being conducted at the
Bohyunsan Optical Astronomy Observatory (BOAO). The nature of the RV variations
was investigated by analyzing the photometric and line shape variations. We
found no variability with the RV period in these quantities and conclude that
the 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-mass
stars, although some unclear interpretations and recent studies may being
calling some planet convictions into question. Nevertheless, the SENS program
is contributing to our knowledge of giant planets around intermediate-mass
stars.
