Sustaining Earth's magnetic dynamo

M Landeau, A Fournier, HC Nataf, D Cébron… - Nature Reviews Earth & …, 2022‏ - nature.com
Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Dynamics and evolution of Venus' mantle through time

T Rolf, M Weller, A Gülcher, P Byrne, JG O'Rourke… - Space Science …, 2022‏ - Springer
The dynamics and evolution of Venus' mantle are of first-order relevance for the origin and
modification of the tectonic and volcanic structures we observe on Venus today. Solid-state …

Venusian habitable climate scenarios: Modeling Venus through time and applications to slowly rotating Venus‐like exoplanets

MJ Way, AD Del Genio - Journal of Geophysical Research …, 2020‏ - Wiley Online Library
One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

Deep magma ocean formation set the oxidation state of Earth's mantle

K Armstrong, DJ Frost, CA McCammon, DC Rubie… - Science, 2019‏ - science.org
The composition of Earth's atmosphere depends on the redox state of the mantle, which
became more oxidizing at some stage after Earth's core started to form. Through high …

The CARMENES search for exoplanets around M dwarfs-Wolf 1069 b: Earth-mass planet in the habitable zone of a nearby, very low-mass star

D Kossakowski, M Kürster, T Trifonov… - Astronomy & …, 2023‏ - aanda.org
We present the discovery of an Earth-mass planet (M b sin i= 1.26±0.21 M⊕) on a 15.6 d
orbit of a relatively nearby (d~ 9.6 pc) and low-mass (0.167±0.011 M⊙) M5. 0 V star, Wolf …

Early bombardment of the moon: Connecting the lunar crater record to the terrestrial planet formation

D Nesvorný, FV Roig, D Vokrouhlický, WF Bottke… - Icarus, 2023‏ - Elsevier
The lunar crater record features∼ 50 basins. The radiometric dating of Apollo samples
indicates that the Imbrium basin formed relatively late—from the planet formation …

Venus, the Planet: Introduction to the evolution of Earth's sister planet

JG O'Rourke, CF Wilson, ME Borrelli, PK Byrne… - Space Science …, 2023‏ - Springer
Venus is the planet in the Solar System most similar to Earth in terms of size and (probably)
bulk composition. Until the mid-20th century, scientists thought that Venus was a verdant …

The role of early giant-planet instability in terrestrial planet formation

D Nesvorný, FV Roig, R Deienno - The Astronomical Journal, 2021‏ - iopscience.iop.org
The terrestrial planets are believed to have formed by violent collisions of tens of lunar-to
Mars-size protoplanets at time t< 200 Myr after the protoplanetary gas disk dispersal (t 0) …

Venus interior structure and dynamics

SE Smrekar, A Davaille, C Sotin - Space Science Reviews, 2018‏ - Springer
No two rocky bodies offer a better laboratory for exploring the conditions controlling interior
dynamics than Venus and Earth. Their similarities in size, density, distance from the sun, and …

Regional stratification at the top of Earth's core due to core–mantle boundary heat flux variations

J Mound, C Davies, S Rost, J Aurnou - Nature Geoscience, 2019‏ - nature.com
Earth's magnetic field is generated by turbulent motion in its fluid outer core. Although the
bulk of the outer core is vigorously convecting and well mixed, some seismic, geomagnetic …
