Due to their transitionary nature , yellow supergiants provide a critical challenge for evolutionary modeling .
Previous studies within M31 and the SMC show that the Geneva evolutionary models do a poor job at predicting the lifetimes of these short-lived stars .
Here we extend this study to the LMC while also investigating the galaxy ’ s red supergiant content .
This task is complicated by contamination by Galactic foreground stars that color and magnitude criteria alone can not weed out .
Therefore , we use proper motions and the LMC ’ s large systemic radial velocity ( \sim 278 km s ^ { -1 } ) to separate out these foreground dwarfs .
After observing nearly 2,000 stars , we identified 317 probable yellow supergiants , 6 possible yellow supergiants and 505 probable red supergiants .
Foreground contamination of our yellow supergiant sample was \sim 80 % , while that of the the red supergiant sample was only 3 % .
By placing the yellow supergiants on the H-R diagram and comparing them against the evolutionary tracks , we find that new Geneva evolutionary models do an exemplary job at predicting both the locations and the lifetimes of these transitory objects .
