Fundamental effective temperature measurements for eclipsing binary stars (2022)
Thesis
Miller, N. J. (2022). Fundamental effective temperature measurements for eclipsing binary stars. (Thesis). Keele University

Modern high-precision spectroscopy and photometry has made it possible to directly measure masses and radii for stars in detached eclipsing binaries (DEBs) to 0.5% or better. These stars, due to their wide orbits, are suitable for testing models of s... Read More about Fundamental effective temperature measurements for eclipsing binary stars.
