HOW DOES STELLAR METALLICITY AFFECT THE ROTATION EVOLUTION OF LOW-MASS STARS? - VICTOR SEE

In recent years, there has been a growing body of evidence that the metallicity of a star affects how efficient its dynamo is. The central idea is that a star’s metallicity affects the depth of its convection zone and, therefore, the dynamo process. Metal-rich stars are expected to generate stronger magnetic fields and have stronger activity than metal-poor stars. From theoretical considerations, a star’s metallicity is also expected to affect its rotation evolution since angular momentum loss is ultimately a result of the dynamo. In this talk, I will present observational evidence that this is indeed the case.
