The Evolution of Jupiter and Saturn as a Function of the Rρ Parameter

The Astrophysical Journal
Computed using the APPLE planetary evolution code, we present updated evolutionary models for Jupiter and Saturn that incorporate helium rain, nonadiabatic thermal structures, and “fuzzy” extended heavy-element cores.

Evolution of Semiconvective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets

The Astrophysical Journal Letters
Recent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have “fuzzy” cores, i.e., gradients of the concentration of heavy elements that might span a large fraction of the planet’s radius.

A Possible Mechanism to Explain the Prograde Equatorial Jet of a Jupiter-like Gaseous Giant

The Astrophysical Journal Letters
Gaseous giants are characterized by their deep atmospheres, which lack clear boundaries with their interiors; therefore, their internal states could directly influence atmospheric dynamics. So far, most modeling studies have considered deep convection as

Searching for GEMS: TOI-7149 b, an Inflated Giant Planet Causing a 12% Transit of a Fully Convective M-dwarf

The Astronomical Journal
We describe the discovery and characterization of TOI-7149 b, a 0.705 ± 0.075 M _J , 1.18 ± 0.045 R _J gas giant on a ∼2.65 days period orbit transiting an M4V star with a mass of 0.344 ± 0.030 M _⊙ and an effective temperature of 3363 ± 59 K. The planet

Transiting Jupiters around M Dwarfs Have Similar Masses to FGK Warm Jupiters

The Astrophysical Journal
This paper presents a comparative analysis of the bulk properties (mass and radius) of transiting giant planets (≳8 R _⊕ ) orbiting FGKM stars. Our findings suggest that the average mass of M-dwarf Jupiters is lower than that of their solar-type ...
