The word "eclipse" means to block the view of something. We usually use the word "eclipse" when the Moon blocks the Sun's light and casts a shadow on the Earth, or when the Earth blocks the Sun's light and casts a shadow on the Moon.
If two stars are orbiting their system center of gravity, and IF the plane of their orbits passes through our solar system, then sometimes one star will block our view of the other one.
If the two stars are different enough, then we'll see variation in the combined light that reaches the Earth. For example, if one is a red giant and the other is a bluish star, then usually we'll see the combined light output, but sometimes we'll see more blue light (when it is blocking the red star) and sometimes we'll see more red light and not much blue (when the red giant is blocking our view of the blue star).
The Kepler Space Telescope worked pretty much the same way, before its gyros failed.
Binary stars can be any color that stars can be. There's no need for the two stars in a binary to be the same color.
One of the propounders of the binary star theories is the German astronomer Friedrich Wilhelm Bessel. Bessel was a pioneering figure in the field of astronomy and made significant contributions to the study of binary star systems. His work laid the foundation for our understanding of how binary stars interact and evolve over time.
Yes, it is.
because binary system is the easy way to understand the inputs and outputs. and it has inly two values 1 or 0;

A binary star consists of two stars gravitationally locked together in a mutual orbit. If the plane of that orbit is in line with us, as observers, then occasionally, one star will eclipse the other, producing a change in luminosity as one star is briefly blocked from view.

That's an 'eclipsing binary'.
"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.
Yes. Zeta Tauri, Kappa Tauri, and Lambda Tauri are eclipsing binary stars.
That happens in an "eclipsing binary".
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.
Each of those is an eclipsing binary.
Yes, because it is easier to determine the precise times of their mutual orbits, which allows us to calculate their masses.
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.
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.
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.
