Cross‐Orogen Granite Migration as an Indicator of Slab Rollback Along Eastern Gondwana
Geochemistry, Geophysics, Geosystems, 2023 Slab rollback during subduction plays a key role in controlling continental growth at convergent plate boundaries. The dynamics of currently subducting slabs can be precisely constrained using geophysical techniques. In contrast, ancient episodes of slab

True Polar Wander of Lava Worlds
The 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.

Introduction. Photosynthetic and atmospheric evolution [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2008 The evolution of photosynthesis remade the Archaean Earth. Before photosynthesis, the air and oceans were anoxic. Now the air is a biological construction, a fifth of which is free molecular oxygen, and the ocean can sustain animal life even in the depths.

The Ultramassive White Dwarf EUVE J1746-706 [PDF]
, 1996 We have obtained new optical and extreme ultraviolet (EUV) spectroscopy of the ultramassive white dwarf EUVE J1746-706. We revise Vennes et al.'s (1996a, ApJ, 467, 784) original estimates of the atmospheric parameters and we measure an effective ...

A secular increase in continental crust nitrogen during the Precambrian [PDF]
, 2017 Recent work indicates the presence of substantial geologic nitrogen reservoirs in the mantle and continental crust. Importantly, this geologic nitrogen has exchanged between the atmosphere and the solid Earth over time. Changes in atmospheric nitrogen (i.

The Search for Atmospheric Laminar Channels: Experimental Results and Method Dissemination
Sensors, 2021 In this paper, a practical application of theoretical developments found in our previous works is explored in relation to atmospheric lidar data. Multifractal structures, previously named “laminar channels”, have been identified in atmospheric profiles ...

Helium Atmospheres on Warm Neptune- and Sub-Neptune-Sized Exoplanets and Applications to GJ 436 b [PDF]
, 2015 Warm Neptune- and sub-Neptune-sized exoplanets in orbits smaller than Mercury's are thought to have experienced extensive atmospheric evolution. Here we propose that a potential outcome of this atmospheric evolution is the formation of helium-dominated ...

Massive peatland carbon banks vulnerable to rising temperatures
Nature Communications, 2020 One-third of Earth’s carbon is sequestered in peatlands, and its stability in the face of climate change is unknown. Here the authors show that warming leads to the release of carbon as methane, but only the most prolonged warming leads to the breakdown ...

Improving 1D Stellar Models with 3D Atmospheres [PDF]
, 2016 Stellar evolution codes play a major role in present-day astrophysics, yet they share common issues. In this work we seek to remedy some of those by the use of results from realistic and highly detailed 3D hydrodynamical simulations of stellar ...
