We present three giant stars from the ongoing Penn State-Torun Planet Search with the Hobby-Eberly Telescope, which exhibit radial velocity (RV) variations that point to the presence of planetary-mass companions around them. BD +49 828 is a M = 1.52 ± 0.22M_☉ K0 giant with a m sin i = 1.6 _–0.2^+0.4 minimum mass companion in a = 4.2^+0.32_–0.2 AU (2590⁺³⁰⁰_–180d), e = 0.35^+0.24_–0.10orbit. HD 95127, a = 4.2 _–0.2^+0.32AU (2590_–180⁺³⁰⁰d), e = 0.35_–0.10^+0.24robit, HD 95127, a log L/L_☉ = 2.28 ± 0.38, R = 20 ± 9 R_☉, M = 1.20 ± 0.22 M_☉ K0 giant, has a m sin i = 5.01_–0.44^+0.61 M_J minimum mass companion in a = 1.28^+0.01_–0.01AU (482⁺⁵_–5d), e = 0.11^+0.15_–0.06orbit. Finally, HD 216536 is a M = 1.36 ± 0.38 M_☉ K0 giant with a m sin i = 1.47_–0.12^+0.20M_J minimum mass companion in a = 0.609 _–0.002^+0.002 AU (148.6 _–0.7^+0.7d), e = 0.38^+0.12_–0.10orbit. Both HD 95127 b and HD 216536 b in their compact orbits are very close to the engulfment zone and hence prone to ingestion in the near future. BD+49 828 b is among the longest-period planets detected with the RV technique until now and it will remain unaffected by stellar evolution up to a very late stage of its host. We discuss general properties of planetary systems around evolved stars and planet survivability using existing data on exoplanets in more detail.
