What role do binary stars play in eclipsing binaries?
Binary stars in eclipsing binaries orbit each other in such a way that from our viewpoint on Earth, they regularly pass in front of each other, causing eclipses. By studying the light curves during these eclipses, astronomers can infer information about the stars' sizes, masses, and orbital dynamics. This makes eclipsing binaries important for understanding stellar properties and evolution.
Eclipsing binary star in Perseus?
An eclipsing binary star in Perseus is a system where two stars orbit each other in such a way that they periodically pass in front of each other, causing eclipses and variations in brightness as viewed from Earth. By studying these changes in brightness, astronomers can determine important properties of the stars, such as their masses and radii.
What does a eclipsing binary look like?
An eclipsing binary system consists of two stars orbiting each other in such a way that they periodically pass in front of each other as seen from Earth. The light curve of an eclipsing binary system will show regular dips in brightness when one star crosses in front of the other, creating a characteristic pattern of alternating minima and maxima. These dips in brightness are caused by eclipses and can be used to determine various properties of the stars, such as their sizes and masses.
Why is the term 'eclipsing binaries' appropriate to describe binary stars?
The term "eclipsing binaries" is appropriate because these binary star systems pass in front of each other during their orbits, causing eclipses where each star blocks the light of the other. This phenomenon allows astronomers to study the binary system's properties, such as their masses, sizes, and orbital characteristics, by observing changes in brightness during eclipses.
Eclipsing binary stars can sometimes be identified because?
they exhibit periodic variations in brightness as one star passes in front of the other, causing an eclipse-like event. By monitoring these changes in brightness over time, astronomers can determine the properties of the stars within the binary system, such as their sizes, masses, and orbital parameters. This information can provide valuable insights into stellar evolution and the dynamics of binary star systems.
Why are eclipsing binary systems important?
It is easy (with the right equipment ) to measure the periodicity of the eclipsing system and thereby the rotational speeds and thereby the relative masses and thereby (with the brightness) the distance and all sorts of other things.
What information can be gained from the light curves of eclipsing binaries?
By studying the variation of the light from an eclipsing binary's light curve, astronomers can derive detailed information not only about the stars' orbits and masses, but also about their radii.(McMillian)
Are eclipsing binary stars better for determining masses than non-eclipsing binaries?
Yes, because it is easier to determine the precise times of their mutual orbits, which allows us to calculate their masses.

What is an eclipsing binary?
An eclipsing binary is a system of two stars that orbit each other in such a way that they periodically pass in front of each other from our perspective on Earth, causing their combined brightness to fluctuate. By measuring these fluctuations, astronomers can determine properties of the stars, such as their sizes, masses, and orbital characteristics.
How can stellar masses be determined by observing binary star systems?
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
What are Binary stars used to determine?
The masses of the two stars.
In an eclipsing binary system, how is the period of orbit determined?
In an eclipsing binary system, the period of orbit is determined by measuring the time it takes for one star to pass in front of the other, causing an eclipse. This period is influenced by the masses and distances of the stars in the system.
