Near-infrared variability in dusty white dwarfs: tracing the accretion of planetary material

Laura K. Rogers, Siyi Xu, Amy Bonsor +4

The inwards scattering of planetesimals towards white dwarfs is expected to be a stochastic process with variability on human time-scales. The planetesimals tidally disrupt at the…

The MESAS Project: ALMA observations of the F-type stars Lep, Vir A, and Vir B

Jacob Aaron White, F. Tapia-Vázquez, A. G. Hughes +7

The spectrum of stars in the submillimeter to centimeter wavelength range remains poorly constrained due to a lack of data for most spectral types. An accurate characterization of…

A minimum-hypothesis explanation for the Radcliffe Wave: Kelvin-Helmholtz instability

Robert Fleck

It is suggested that the wavelike character of the recently discovered 2.7-kiloparsec spatially and kinematically coherent complex of interstellar clouds in the solar neighborhood-…
