Two stars orbiting each other so that one regularly passes in front of the other blocking out some or all of light of the hidden star.

What is a binary star system in which one star periodically blocks the light from another?
That's an 'eclipsing binary'.
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.
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 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.
How can you tell if a star system is an eclipsing binary system?
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.
Why are some binary stars called eclipsing?
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.
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)
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.
