Why can certain stars sometimes be identified as eclipsing binary stars?

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.

What colors are binary stars?
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.
What does the 1 in binary number 100000 means?
The digit 1 in the binary number 100000 represents 32.
Who is one of the propounders of the binary star theories?
All serious astronomers realize that there are binary stars.
Who used binary code for computers?
Yes, it is.
Why do you use binary system in digital electronics?
because binary system is the easy way to understand the inputs and outputs. and it has inly two values 1 or 0;
Eclipsing binary stars can sometimes be identified because?
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.
Which star system is an eclipsing binary?
algol
Eclipsing binary star in Perseus?
Algol
Why can certain stars sometimes be identified as eclipsing bininary stars?
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.
Which type of binary can have their sizes measured directly by photometry?
eclipsing
A star system in which on star blocks the light from another is called?
"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.
What is a binary star system in which one star periodically blocks the light from another?
That's an 'eclipsing binary'.
Does Taurus have any Binary stars?
Yes. Zeta Tauri, Kappa Tauri, and Lambda Tauri are eclipsing binary stars.
When does one star periodically blocks the light from another star?
That happens in an "eclipsing binary".
What does a eclipsing binary look like?
See related link for a picture of Sirius and it's binary. Sirius B can be found in the bottom left corner.
What is double stars in which one star moves directly in front of the other?
Each of those is an eclipsing binary.
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.
