Assessing the Climate and Habitability of Tidally Locked Rocky Exoplanets

Tidally locked exoplanets orbiting M dwarf stars are prime targets in the search for habitable worlds, yet their complex climate dynamics challenge conventional models of habitability. We homogeneously estimated the liquid–water habitability of exoplanets with the highest up-to-d...

Mantle heterogeneity drives spreading center dynamics at Arctic Mid-Ocean Ridge

The Mohns and Knipovich mid-ocean ridges in the Arctic Ocean are ideal settings to investigate the dynamics of spreading centers, being the region affected by intricate interplays between oblique plate kinematics and curved plate boundary geometry. Furthermore, significant mantle...

Does an Unconventional Source with a High Silica Content (Obsidian) or a High Alumina Content (Bauxite) Affect the Type of Potassium Zeolite Formation? Preliminary Data on Synthetic Products’ Efficiency in Ammonium Removal

In this paper, obsidian (OS) and bauxite (BX) are used to synthesize zeolites via KOH prefusion, followed by a conventional hydrothermal process (HY) or an unconventional vapor-phase crystallization method (VPC) at 90 °C. The results indicate that, due to their chemical and miner...

Early-mid Holocene Ross Sea extreme wave heights reflect sea ice retreat and ocean-atmosphere interactions

Abstract Antarctic coastal systems preserve valuable records of postglacial environmental change and extreme storm events. On Inexpressible Island, Ross Sea, we integrated geomorphic mapping, boulder measurements, exposure dating, radiocarbon constraints, and hydrodynamic analysi...
