Massive star formation and cluster evolution (A05)

• Subject Area: Astrophysics and Astronomy
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 500700252

In A5, we investigate the formation and evolution of massive stars and their associated star clusters by combining state-of-the-art magneto-hydrodynamic and N-body simulations. We will probe the full development cycle of (sub-)clusters hosting massive stars, from massive star formation through to the stage at which the star formation process is locally completed and the remaining gas is unbound via stellar feedback. The habitats we model are inspired by the complementary observational projects within this CRC. We will investigate whether the massive stars’ habitat determines the fate of the final cluster, i.e. whether it remains bound or becomes unbound and forms an association. The long-term dynamical evolution will finally reveal in which habitats either short-lived or long-lived clusters preferentially form.
