However, an extreme group of eclipsing, mass-transferring binaries, known as W Serpentis stars or "hyperactive Algols", do have accretion disks and may be in a pre-Algol-type stage. Algol stars are among the most important kind of star systems in terms of the information they provide on stellar masses and sizes.

Algol seems to get dimmer when the K star passes between the B star and the earth, blocking the B star's light. It also gets dimmer when the K star ducks behind and the B star blocks it. Algol is brightest, of course, when you have an unobstructed view of both stars.

If you watch an eclipsing binary night after night for a while (sometimes weeks, sometimes months or more), you can actually notice the star become darker and then brighter when this happens. For a star as bright as Algol, you don't even need a telescope to see the change.
