We present the discovery of substellar-mass companions to three stars by the ongoing Penn State–Toruń Planet Search conducted with the 9.2 m Hobby–Eberly Telescope. The K2-dwarf, BD+14 4559, has a 1.5 MJ minimum mass companion with the orbital period of 269 days and shows a non-linear, long-term radial velocity (RV) trend, which indicates a possible presence of another planet-mass body in the system. The K3-giant, HD 240210, exhibits RV variations that require modeling with multiple orbits, but…
