Algol is an "eclipsing binary", meaning there are two stars, one of which regularly covers the other. When that happens, we receive less light from the pair.

What is the Algol paradox?

In many binary stars, there can be a flow of material between the two stars, disturbing the normal process of stellar evolution. As the flow progresses, the evolutionary stage of the stars will advance, even as the relative masses change. Eventually, the originally more massive star will reach the next stage in its evolution despite having lost much of its mass to its companion.


What is Brightest star dog or ghoul star?

Siriusis also known colloquially as the "Dog Star", reflecting its prominence in its constellation, Canis Major (English: Big Dog).Sirius can be seen from almost every inhabited region of the Earth's surface, with only those North of 73 degrees unable to see it. In early July, Sirius is a binary star and can be seen in both the evening where it sets after the sun, and in the morning where it rises before the sunghoul star Algol. This star's proper name comes from the Arabic for head of the ghoul, or head of the demon.This star is known to vary in brightness over a regular time interval. The cycle lasts exactly 2 days, 20 hours and 49 minutes. All the while, the star remains visible to the eye. Algol's brightness variations are not due to some special quality of a single star. In fact, this is a multiple star system, where one star regularly passes in front of another as seen from our earthly perspective.Early stargazers had no way to know why Algol varied in brightness. But it's likely that they did notice this star's brightness change. Throughout parts of the ancient world, Algol was associated with demons or monsters. The Greeks and Romans identified the star with the Head of Medusa, a fearful monster with snakes in place of hair. The star has also been called The Ghoul Star.

What is the surface and color temperature of Algol?

Algol, also known as Beta Persei, is a binary star system with a surface temperature of approximately 7,500 Kelvin for its primary star. This temperature gives it a bluish-white color in the visible spectrum. The secondary star in the system is cooler, with a surface temperature around 5,000 Kelvin, resulting in a yellowish hue. Overall, Algol is known for its significant brightness and variability.
