The Sonora Substellar Atmosphere Models. VII. Flame Skimmer: Cloud-free Atmospheric and Evolutionary Models for the Coldest Substellar Objects

The Astrophysical Journal
JWST has provided unprecedented access to ultracool brown dwarfs and has pushed the boundaries of directly imaging temperate giant planets. As we continue to push toward detecting sub-Saturn and Neptune-like planets, it is crucial to develop atmospheric ...

Constraints on the Long-term Existence of Dilute Cores in Giant Planets

The Planetary Science Journal
Post-Cassini ring seismology analysis suggests the existence of a stable stratification inside Saturn that extends from the center to ∼60% of its radius, in what is recognized today as Saturn’s dilute core.

Penetrative Convection in Rotating Tilted f-plane with Multiple Radiative and Convective Layers

The Astrophysical Journal
In this paper, we conducted a linear instability analysis to investigate penetrative convection in rotating, tilted f -planes with multiple convectively stable and unstable layers. Our findings indicate that penetrative distance decreases with increasing

On the Meaning of the Dynamo Radius in Giant Planets with Stable Layers

The Astrophysical Journal
Current structure models of Jupiter and Saturn suggest that helium becomes immiscible in hydrogen in the outer part of the planets’ electrically conducting regions.

Changes in the metallicity of gas giant planets due to pebble accretion

, 2018
We run numerical simulations to study the accretion of gas and dust grains on to gas giant planets embedded into massive protoplanetary discs. The outcome is found to depend on the disc cooling rate, planet mass, grain size, and irradiative feedback from

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534 b

The Astrophysical Journal Letters
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534 b, the first transiting planet known to orbit a white dwarf (WD) star.

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-dependent Variability Driven by Multiple Mechanisms

The Astrophysical Journal Letters
Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate their heat from formation as they cool, primarily at infrared wavelengths ...
