Asteroseismology of Eclipsing Binary Stars in the Kepler Era
Eclipsing binary stars have long served as benchmark systems to measure
fundamental stellar properties. In the past few decades, asteroseismology - the
study of stellar pulsations - has emerged as a new powerful tool to study the
structure and evolution of stars across the HR diagram. Pulsating stars in
eclipsing binary systems are particularly valuable since fundamental properties
(such as radii and masses) can determined using two independent techniques.
Furthermore, independently measured properties from binary orbits can be used
to improve asteroseismic modeling for pulsating stars in which mode
identifications are not straightforward. This contribution provides a review of
asteroseismic detections in eclipsing binary stars, with a focus on space-based
missions such as CoRoT and Kepler, and empirical tests of asteroseismic scaling
relations for stochastic ("solar-like") oscillations.Comment: 28 pages, 12 figures, 2 tables; Proceedings of the AAS topical

The Strategies of the Spanish cotton textile companies before the Civil War: the road to longevity
This study, based on family business theories, offers an innovative vision of the Spanish cotton industry. It proves that Spanish cotton companies, just like their European counterparts, implemented a strategy that was consistent with their nature as family businesses and went beyond the economic-institutional frames within which they developed. The article identifies this strategy as `conservative, because its main objectives were longevity and family control and because it was based on a high percentage of own resources, low levels of indebtedness and organic growth, thus sacrificing profitability for the sake of security.Universidad Pablo de OlavidePostprin
