Multiverse Predictions for Habitability: Fraction of Planets that Develop Life

open access: yesUniverse, 2019
In a multiverse context, determining the probability of being in our particular universe depends on estimating its overall habitability compared to other universes with different values of the fundamental constants.

Lithium Isotope Evidence for Enhanced Continental Weathering at ∼1.4 Ga

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The Mesoproterozoic (ca. 1.6–1.0 Ga) is primarily characterized by pervasive tectonic stasis under greenhouse climate. However, the coeval weathering regime still remains elusive. Here, we conduct comprehensive investigations (including detrital δ7Li values, elemental compositions, and clay mineral assemblage) on the 1.4‐billion‐year‐old iron ...

Prospects of Using Tidal Tomography to Constrain Ganymede's Interior

open access: yesGeophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Juice (JUpiter ICy moons Explorer) 3GM Radio Science Experiment will map the gravitational field of Ganymede with unprecedented accuracy and measure tidally‐induced variations. These measurements will allow the characterization of its putative ocean and may resolve lateral variations in internal structure.

Magmatic evolution and architecture of an oceanic intraplate volcano: Vesteris Seamount, Atlantic Ocean

open access: yesFrontiers in Earth Science
Vesteris is a large (33 × 27 km) and young (summit age: 0.65–0.010 Ma) intraplate seamount in the Greenland Sea, formed from ocean island basalt (OIB) magmatism.

Influence of Orbit and Mass Constraints on Reflected Light Characterization of Directly Imaged Rocky Exoplanets

open access: yesThe Astrophysical Journal Letters
Survey strategies for upcoming exoplanet direct imaging missions have considered varying assumptions of prior knowledge. Precursor radial velocity surveys could have detected nearby exo-Earths and provided prior orbit and mass constraints. Alternatively,
