TESS obs. of massive O and B stars

Uncertainties in stellar structure and evolution theory are largest for stars undergoing core convection on the main sequence. A powerful way to calibrate the free parameters...恒星结构与演化理论中的不确定性，在处于主序（main sequence）阶段并发生核对流（core convection）的恒星中最为显著。校准其自由参数的有效途径之一为……
