Classical Cepheids in the 4MOST era I: Methodology for 4MOST variable stars and NLTE abundance gradients in the Milky Way
R. Albarracín, M. Bergemann, N. Storm +9
Classical Cepheids (CCs) are key distance indicators and tracers of young stellar populations in the Milky Way. Their period-luminosity-metallicity (PLZ) relation also makes them c…

Gravitational Capture of Large Interstellar Planetesimals by Collapsing Prestellar Cores
Richard Anderson, Kedron Silsbee
We investigate the capture of free-floating planetesimals by the time-varying gravitational potential of a collapsing prestellar core. We use one-dimensional collapse models to est…
