Detached eclipsing binaries are a fundamental tool for measuring the physical
parameters of stars that are effectively evolving in isolation. Starting from
more than 40,000 eclipsing binary candidates identified by the All-Sky
Automated Survey for Supernovae (ASAS-SN), we use PHOEBE to determine the sum
of the fractional radii, the ratio of effective temperatures, the inclinations,
and the eccentricities for 35,464 systems. We visually inspect all the light
curve models to verify the model fits and examine the TESS light curves, when
available, to select systems with evidence for additional physics, such as
spots, mass transfer, and hierarchical triples. We examine the distributions of
the eclipsing binary model parameters and the orbital parameters. We identify
two groups in the sum of the fractional radii and effective temperature ratio
parameter space that may distinguish systems approaching the semidetached
limit. Combining Gaia EDR3 with extinction estimates from 3-dimensional dust
maps, we examine the properties of the systems as a function of their absolute
magnitude and evolutionary state. Finally, we present light curves of selected
eclipsing binaries that may be of interest for follow-up studies.
