# Pulsation Theory Models for Cepheids in Eclipsing Binary Systems

## TL;DR

This paper compares pulsation theory models with recently measured physical parameters of Cepheids in eclipsing binary systems, confirming good agreement and refining stellar models.

## Contribution

It provides a detailed comparison between pulsation models and observed data for Cepheids, improving understanding of their physical parameters and pulsation modes.

## Key findings

- Models generally agree with observed periods and parameters
- Some parameters are further constrained by the comparison
- Results support the accuracy of pulsation theory for Cepheids

## Abstract

Physical parameters were recently measured for several Cepheids in eclipsing binary systems in the LMC. It is a good opportunity to compare these results with models obtained from pulsation theory. Having well determined physical parameters of the stars, we can calculate the corresponding pulsation periods for a given mode and check for instability. For stars that lack data, unknown or poorly defined parameters can be further constrained. We present the comparison for six Cepheids, showing that, in general, the results are in very good agreement.
