The influence of metallicity on a combined stellar and disk evolution

Context. Determining the effects of an accretion disk is crucial to understanding evolution young stars. During combined evolution, stellar and parameters influence one another, which motivated us develop a model. This makes numerical model, with evolving alongside star, next logical step in progress studying early evolution. Aims. We aim understand metallicity on spin during T Tauri phase. Methods. treatment hydrodynamic including model allowing self-consistent calculation back-reactions between individual components. Results. present theoretical stars coupled disk. find that disks low-metallicity environments are heated differently have shorter lifetimes compared their solar-metallicity counterparts. Differences radii, contraction rate radius, result rotating more rapidly. Conclusions. additional explanation for observed short clusters. A combination our those previous studies (e.g., metallicity-based photo-evaporation) could help dispersal at different metallicities. Furthermore, includes several important had previously been ignored magnetic field strength realistic lifetime). encourage others include results as initial or input further models cover toward main sequence.
