Query: Outward migration of Jupiter and Saturn in 3:2 or 2:1 resonance in
  radiative disks: implications for the Grand Tack and Nice models   Embedded in the gaseous protoplanetary disk, Jupiter and Saturn naturally
become trapped in 3:2 resonance and migrate outward. This serves as the basis
of the Grand Tack model. However, previous hydrodynamical simulations were
restricted to isothermal disks, with moderate aspect ratio and viscosity. Here
we simulate the orbital evolution of the gas giants in disks with viscous
heating and radiative cooling. We find that Jupiter and Saturn migrate outward
in 3:2 resonance in modest-mass ($M_{disk} \approx M_{MMSN}$, where MMSN is the
"minimum-mass solar nebula") disks with viscous stress parameter $\alpha$
between $10^{-3}$ and $10^{-2} $. In disks with relatively low-mass ($M_{disk}
\lesssim M_{MMSN}$) , Jupiter and Saturn get captured in 2:1 resonance and can
even migrate outward in low-viscosity disks ($\alpha \le 10^{-4}$). Such disks
have a very small aspect ratio ($h\sim 0.02-0.03$) that favors outward
migration after capture in 2:1 resonance, as confirmed by isothermal runs which
resulted in a similar outcome for $h \sim 0.02$ and $\alpha \le 10^{-4}$. We
also performed N-body runs of the outer Solar System starting from the results
of our hydrodynamical simulations and including 2-3 ice giants. After dispersal
of the gaseous disk, a Nice model instability starting with Jupiter and Saturn
in 2:1 resonance results in good Solar Systems analogs. We conclude that in a
cold Solar Nebula, the 2:1 resonance between Jupiter and Saturn can lead to
outward migration of the system, and this may represent an alternative scenario
for the evolution of the Solar System.
