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)
Telescopes have aided scientists a lot in determining whether a star is binary or not. The visual binaries can be seen through a telescope or even high powered binoculars. Observing the spectral light of a star can aid in determining whether it is binary. Eclipsing binaries give themselves away by the variability of their light.
No, Algol and Mira are different astronomical objects. Algol is a binary star system located in the constellation Perseus, while Mira is a red giant star in the constellation Cetus. Both are variable stars, but they are not related astronomically.
Binaries, or binary star systems, are crucial to astronomers because they provide valuable insights into stellar masses, compositions, and evolutionary stages. By observing the orbital dynamics of binary stars, astronomers can accurately determine their masses using Kepler's laws, which is essential for understanding stellar formation and evolution. Additionally, binaries can reveal information about stellar interactions and phenomena such as mass transfer, which can lead to the formation of exotic objects like neutron stars and black holes. Overall, studying binaries enhances our comprehension of the universe's structure and the life cycles of stars.
Generally the main star as this will have the most mass. However, temperature is not necessarily based on mass, so a secondary unit, could well be hotter but less massive.
Eclipsing binaries.
They are pair of stars - hence binaries - which orbit one another. Strictly speaking, they orbit their centre of mass. Anyway, due to their motion each one will alternately eclipse the other - hence eclipsing.
Visual Binaries are rare compared to spectroscopic binaries because visual binaries have widely separated members bright enough to be observed and monitored separately.The orbital plane of the pair of stars in Eclipsing Binariesare almost edge-on to our line of sight. In this case we observe a periodic decrease of starlight intensity as one member of the binary passes in front of the other.Spectroscopic Binaries are too distant from us to be resolved into separate stars, but they can be indirectly perceived by monitoring the back-and-forth Doppler shifts of their spectral lines as the stars orbit one another and their line-of-sight velocities vary periodically.To summarize, Visual Binaries and Eclipsing Binariesare harder to identify and observe compared to the Spectroscopic Binaries, therefore Visual Binaries and Eclipsing Binaries are much more rare.McMillan, Chaisson , et. al.

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.
Yes, because it is easier to determine the precise times of their mutual orbits, which allows us to calculate their masses.
Because in eclipsing binaries, the two stars orbit each other regularly passing in front of the other, blocking out some or all of light of the hidden star.

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.
A photometer is an instrument used to measure light intensity, therefore, the eclipsing binaries are best studied as we observe a periodic decrease of sunlight intensity as one member of the binary passes in front of the other.

A binary star system consists of two stars that are gravitationally bound and orbit around a common center of mass. These systems can vary in their characteristics, including the distance between the stars, their sizes, and luminosities. Binary stars are crucial for astrophysics, as they allow scientists to determine stellar masses and study stellar evolution through their interactions and orbital dynamics. There are different types of binary stars, including visual binaries, spectroscopic binaries, and eclipsing binaries, each offering unique insights into their properties.
