Detailed Calculations of the Efficiency of Planetesimal Accretion in the Core-Accretion Model -III: The Contribution of Planetesimals Beyond Saturn
Nader Haghighipour, Morris Podolak, Esther Podolak
Continuing our initiative on advancing the calculations of planetesimal accretion in the core-accretion model, we present here the results of our recent study of the contributions…
Uranus and Neptune as methane planets: producing icy giants from refractory planetesimals
Uri Malamud, Morris Podolak, Joshua Podolak +1
Uranus and Neptune are commonly considered ice giants, and it is often assumed that, in addition to a solar mix of hydrogen and helium, they contain roughly twice as much water as…
H-Atmospheres of Icy Super-Earths Formed in situ in the Outer Solar System: An Application to a Possible Planet Nine
Amit Levi, Scott J. Kenyon, Morris Podolak +1
We examine the possibility that icy super-Earth mass planets, formed over long time scales (0.1--1~Gyr) at large distances ( 200--1000~AU) from their host stars, will develop…
The Evolution and Internal Structure of Jupiter and Saturn with Compositional Gradients
A. Vazan, R. Helled, M. Podolak +1
The internal structure of gas giant planets may be more complex than the commonly assumed core-envelope structure with an adiabatic temperature profile. Different primordial intern…
Convection and Mixing in Giant Planet Evolution
Allona Vazan, Ravit Helled, Attay Kovetz +1
The primordial internal structures of gas giant planets are unknown. Often giant planets are modeled under the assumption that they are adiabatic, convective, and homogeneously mix…
Structure and Dynamics of Cold Water Super-Earths: The Case of Occluded CH4 and its Outgassing
Amit Levi, Dimitar Sasselov, Morris Podolak
We study the transport of methane in the external water envelopes surrounding water-rich super-Earths and estimate its outgassing into the atmosphere. We investigate the influence…
The Effect of Composition on the Evolution of Giant and Intermediate-Mass Planets
A. Vazan, A. Kovetz, M. Podolak +1
We model the evolution of planets with various masses and compositions. We investigate the effects of the composition and its depth dependence on the long-term evolution of the pla…
