New Frontiers in Binary Stars: Science at High Angular Resolution
Abstract
The mass of a star determines how it evolves throughout its lifetime from beginning to end. Understanding the fundamental relationships between stellar mass, luminosity, and radius over a range of metallicities from the current solar values to the extremely low metallicities representative of the early universe is essential to the study of stellar astrophysics. This requires measuring high precision masses for stars over a wide range of evolutionary stages. Such masses can be obtained through mapping the three-dimensional orbits of binary stars. Continuing to apply this technique to shorter period binaries and to fainter or more distant systems over the next decade requires continued access to the highest angular resolution measurements, such as those achieved through long baseline optical/infrared interferometry.
