Abstract:
Heavy elements, even though its smaller constituent, are crucial to
understand Jupiter formation history. Interior models are used to
determine the amount of heavy elements in Jupiter interior,
nevertheless this range is still subject to degeneracies due to
uncertainties in the equations of state.
Prior to Juno mission data arrival, we present Jupiter optimized
calculations exploring the ect of different model parameters in the
determination of Jupiter's core and heavy element's mass. We
perform comparisons between equations of state published recently.
The interior model of Jupiter is calculated from the equations of
hydrostatic equilibrium, mass and energy conservation, and energy
transport. The mass of the core and heavy elements is adjusted to
match Jupiter's observational constrains radius and gravitational
moments
Description:
In this study we use three different equations of state for hydrogen
and helium: the widely used Saumon et al. (1995ApJS...99..713S 1995ApJS...99..713S)
equations of state, and the more recent equations of state derived
from Ab initio calculations published by Militzer & Hubbard (2013,
Cat. J/ApJ/774/148) and by Becker et al. (2014, Cat. J/ApJS/215/21).
We present
- MH13+SCvH-H hydrogen EOS calculated based on Militzer & Hubbard
(2013, Cat. J/ApJ/774/148) and Saumon et al. (1995ApJS...99..713S 1995ApJS...99..713S)
- REOS3b-H hydrogen EOS calculated based on Becker et al. (2014, Cat.
J/ApJS/215/21)
- REOS3b-He helium EOS calculated based on Becker et al. (2014, Cat.
J/ApJS/215/21)
- REOS3sc-H hydrogen EOS calculated based on Becker et al. (2014, Cat.
J/ApJS/215/21) and Saumon et al. (1995ApJS...99..713S 1995ApJS...99..713S)
- REOS3sc-He helium EOS calculated based on Becker et al. (2014, Cat.
J/ApJS/215/21) and Saumon et al. (1995ApJS...99..713S 1995ApJS...99..713S)
