Resumen:

Most stars are actually in pairs or triplets. Observing binary stars helps develop stellar evolution theories. If their orbital plane of a binary star system is more or less parallel to the line of sight, one star will block the other as they orbit around each other. This is known as eclipsing binary. In this talk, we will discuss observations of eclipsing binary star systems and what information we can extract from their lightcurves. We will also discuss observations of Jovian satellites and asteroids using our SARA (Southeastern Association for Research in Astronomy) and Holcomb telescopes.
