Sublimation Temperature of Circumstellar Dust Particles and Its Importance for Dust Ring Formation [PDF]
Dust particles in orbit around a star drift toward the central star by the Poynting-Robertson effect and pile up by sublimation. We analytically derive the pile-up magnitude, adopting a simple model for optical cross sections.

Origin of Silicic Magmatism at the Katla Volcanic Complex, South Iceland
Abstract The Katla volcano is a bimodal caldera complex within Iceland's basalt‐dominated Eastern Volcanic Zone. To unravel the petrogenesis of silica‐rich rocks from Katla, we provide new δ18O values for almost 60 basaltic, intermediate, and high‐silica eruptive rocks, including a number of partially melted felsic xenoliths.
