See related link for a picture of Sirius and it's binary. Sirius B can be found in the bottom left corner.

eclipsing
"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.
The dimmer, secondary star passes in front of the brigher primary star, dimming it.

That's an 'eclipsing binary'.
Yes. Zeta Tauri, Kappa Tauri, and Lambda Tauri are eclipsing binary stars.
That happens in an "eclipsing binary".
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.
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)
