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

The Astronomical Journal
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 ...

Models of the in Situ Formation of Detected Extrasolar Giant Planets

, 1998
We present numerical simulations of the formation of the planetary companions to 47 UMa, ae CrB, and 51 Peg. They are assumed to have formed in situ according to the basic model that a core formed first by accretion of solid particles, then later it ...

Jupiter Evolutionary Models Incorporating Stably Stratified Regions

The Astrophysical Journal
We address the issue of which broad set of initial conditions for the planet Jupiter best matches the current presence of a “fuzzy core” of heavy elements, while at the same time comporting with measured parameters such as its effective temperature ...
