"Occulting binary". The word "occult" means hidden or in shadows; if a binary star's orbital plane happens to be exactly through the Earth's path, we might see two stars when they're separate and then see one of the stars disappear behind (or in front of) the other.
Each of those is an eclipsing binary.
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.
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.
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.

That's an 'eclipsing binary'.

That happens in an "eclipsing binary".
Algol is best classified as a fixed star system in the constellation Perseus. It is actually a binary star system consisting of two stars that eclipse each other from the perspective of Earth. It is one of the best-known eclipsing binary stars and is a popular target for amateur astronomers.

Precisely by the eclipse - that's what an "eclipsing binary system" is all about. The idea is that one of the stars partially (or completely, in some cases) covers the other star; with the result that the combined brightness (as seen from Earth) gets less for some time.
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.
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.
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.
Algol (Demon Star) is a bright star in the constellation Perseus.Algol is actually a triple star system - Beta Persei A, B, and CBeta Persei A has a spectral type of B8 and is a blue-white giantBeta Persei B has a spectral type of K0 and is an orange subgiantSee related link for more information.
