Magnetic fields in early stellar evolution: Improving mass and age estimates for young stars

Inhibition of convection by strong magnetic fields has been implicated as a potential culprit for the observed systematic errors with stellar models predictions. I test this hypothesis using stellar evolution models that include effects of strong magnetic fields on stellar structure and the efficiency of convection. I show that models including inhibition of convection due to magnetic fields produce better age consistency across effective temperature domains and alter the slope of the mass-radius relation to predict an age consistent with the HR diagram.
