Chemical and dynamical evolution of prestellar cores, the dawn of star and planet formation
Studying prestellar cores is crucial to understanding the formation of stellar and planetary systems. To date, we lack a comprehensive survey of their density and velocity structure at small scales (100-1000 au), the gas ionisation state, their lifetimes, and how these properties are influenced by the environment. A deep study into this critical stage of star formation requires a large single-dish (sub)millimetre telescope like AtLAST.
