The magma ocean concept was first conceived to explain the geology of the Moon, but
hemispherical or global oceans of silicate melt could be a widespread “lava world” phase of …

The water content of magma oceans is widely accepted as a key factor that determines
whether a terrestrial planet is habitable. Water ocean mass is determined as a result not only …

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 …

White dwarfs that have accreted rocky planetary bodies provide unique insights regarding
the bulk composition of exoplanetary material. The analysis presented here uses observed …

We present a comprehensive experimental campaign of high-velocity microparticle impacts
with different combinations of particle and substrate materials to identify possible …

Melting has long been used to join metallic materials, from welding to selective laser melting
in additive manufacturing. In the same school of thought, localized melting has been …

Highly siderophile elements (HSEs) are strongly depleted in the bulk silicate Earth (BSE) but
are present in near-chondritic relative abundances. The conventional explanation is that the …

White dwarfs that have accreted planetary bodies are a powerful probe of the bulk
composition of exoplanetary material. In this paper, we present a Bayesian model to explain …

Late accretion onto the Hadean Earth included large impacts that could have influenced
early habitability, either by sterilizing the planet or alternatively catalyzing the origin of life by …

Growing protoplanets experience a number of impacts during the accretion stage. A large
impactor hits the surface of a protoplanet and produces impact-induced melt, where the …
