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.

What do we call a solar system with 2 stars?
Star system with 2 star called? binary star system
Why does one star seem to disappear in the Algol star system?
The Algol star system is known as an eclipsing binary pair, As such, one star moves in front of the other, blocking it's light. Because the pair are in line with the Earth, it has the effect that one stars seems to disappear. See related link for an animation of the effect.
Color of binary star?
A binary star is not any particular color. A binary star system can contain stars of any spectral type.
The star Algol is better classified as a what type of star?
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.
How far away is the binary star system alrai?
The binary star system Alrai is located about 45 light-years away from the constellation Cepheus. This star system also goes by the name Gamma Cephei.
Which star system is an eclipsing binary?
algol
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.
Eclipsing binary star in Perseus?
Algol
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.
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.
What role do binary stars play in eclipsing binaries?
The dimmer, secondary star passes in front of the brigher primary star, dimming it.
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.
