Discovery of a Jupiter Analog Misaligned to the Inner Planetary System in HD 73344

We present the discovery of a Jupiter-like planet, HD 73344 d ( ${m}_{d}=2.5{5}_{-0.46}^{+0.56}\,{M}_{J}$ , ${a}_{d}=6.7{0}_{-0.26}^{+0.25}$ au, ${e}_{d}=0.1{8}_{-0.12}^{+0.14}$ ) based on 27 yr radial velocity (RV) observations from ELODIE, Lick/Hamilton, SOPHIE, APF, and HIRES. HD 73344 also hosts...
