Abstract:
Optical interferometry provides us with a unique opportunity to
improve our understanding of stellar structure and evolution. Through
direct observation of rotationally distorted photospheres at
sub-milliarcsecond scales, we are now able to characterize latitude
dependencies of stellar radius, temperature structure, and even energy
transport. These detailed new views of stars are leading to revised
thinking in a broad array of associated topics, such as spectroscopy,
stellar evolution, and exoplanet detection. As newly advanced
techniques and instrumentation mature, this topic in astronomy is
poised to greatly expand in depth and influence.
