Recent developments in determining the evolution of magnetic OB stars
Abstract
We review recent developments in determining the evolution of magnetic massive OB stars. One of the important scientific questions is the completeness and the detection limits of contemporaneous spectropolarimetric surveys across the HR diagram. We present the characteristics of the MiMeS survey of O-type stars, and how the limits of the current available observations warrant the design of new high-precision surveys that target the older O-type star population. Another important question is whether the presence of the magnetic fields changes stellar evolutionary tracks in a significant way, hence leading to a wrong determination of stellar parameters. We review new evolution models that include the effect of magnetic wind quenching, and suppression of convection in the iron opacity peak zone.
