Long Baseline Interferometry of Rotating Stars Across the HR Diagram: Flattening, Gravity Darkening, Differential Rotation
Abstract
Stellar rotation has been for a long time considered as a second-order effect on theories of stellar structure and evolution. Modern observations proved that stellar rotation is a key parameter to explain many physical mechanisms on stars. In particular optical/IR long baseline interferometry (OLBI) became a key technique to study stellar rotation across the HR diagram. In this contribution we describe the most important OLBI results obtained in the field of stellar rotation since the beginning of the twenty-first century.
