A Geologic Si‐O‐C Pathway to Incorporate Carbon in Silicates

open access: yesGeophysical Monograph Series, Page 47-54., 2020

This book is Open Access. A digital copy can be downloaded for free from Wiley Online Library.

Explores the behavior of carbon in minerals, melts, and fluids under extreme conditions

Carbon trapped in diamonds and carbonate-bearing rocks in subduction zones are examples of the continuing exchange of substantial carbon ...

The influence of bulk composition on the long-term interior-atmosphere evolution of terrestrial exoplanets [PDF]

open access: yesAstronomy & Astrophysics, 2020
Aims.The secondary atmospheres of terrestrial planets form and evolve as a consequence of interaction with the interior over geological time. We aim to quantify the influence of planetary bulk composition on the interior–atmosphere evolution for Earth-sized terrestrial planets to aid in the interpretation of future observations of terrestrial exoplanet

True Polar Wander of Lava Worlds

open access: yesThe Astrophysical Journal Letters, 2023
As one of the most detectable types of terrestrial planets, lava worlds are highly prioritized targets for exoplanet atmosphere characterization since their atmospheres may reveal what they are made of and how.

Atmospheric circulation of exoplanets

open access: yes地球与行星物理论评, 2023
To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is ...

Conclusive Evidence for a Population of Water Worlds around M Dwarfs Remains Elusive

open access: yesThe Astrophysical Journal Letters, 2023
The population of small, close-in exoplanets is bifurcated into super-Earths and sub-Neptunes. We calculate physically motivated mass–radius relations for sub-Neptunes, with rocky cores and H/He-dominated atmospheres, accounting for their thermal ...

A new set of atmosphere and evolution models for cool T–Y brown dwarfs and giant exoplanets [PDF]

open access: yesAstronomy & Astrophysics, 2020
We present a new set of solar metallicity atmosphere and evolutionary models for very cool brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere models are generated with our state-of-the-art 1D radiative-convective equilibrium code ATMO, and are used as surface boundary conditions to calculate the interior structure and ...

A Radiative-convective Model for Terrestrial Planets with Self-consistent Patchy Clouds

open access: yesThe Planetary Science Journal, 2023
Clouds are ubiquitous: they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet observations.

Zodiacal exoplanets in time – XIII. Planet orbits and atmospheres in the V1298 Tau system, a keystone in studies of early planetary evolution [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Studies of planetary systems of stars in star-forming regions and young clusters open a window on the formative stages of planetary evolution. We obtained high-cadence high-resolution infrared spectroscopy of the solar-mass Taurus association-member V1298 Tau during a transit of its 10R⊕-size ‘b’ planet. We measured the systemic

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...
