One of the propounders of the binary star theories is the German astronomer Friedrich Wilhelm Bessel. Bessel was a pioneering figure in the field of astronomy and made significant contributions to the study of binary star systems. His work laid the foundation for our understanding of how binary stars interact and evolve over time.
Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).
Two stars revolving around one another (around their center of mass, to be precise) are called a "binary star". There is no special name for the case that the brightness is unequal; this is actually the usual case.
One similarty is that both of the theories suggest the Earth is constantly moving.
No the Death Star was a space station created by the empire in Star Wars 3,4 and in star wars 6. The Death Star's power was to destroy a planet with one shot (it did this to Alderan in Star Wars 4).

That's an 'eclipsing binary'.
When two stars are orbiting each other, it is called a binary star system. The stars revolve around a common center of mass due to their gravitational interaction. Binary star systems provide valuable information about stellar properties and evolution.

That happens in an "eclipsing binary".
"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.
A mass-transfer binary is a type of binary star system where one star transfers mass onto its companion due to their close proximity. This transfer of mass can occur through processes such as stellar winds or Roche-lobe overflow. The mass transfer affects the evolution and properties of both stars in the system.
A spectroscopic binary star is detected by observing periodic shifts in the spectral lines of the star indicating the presence of a companion, while a visual binary star is detected through direct observation of two separate stars orbiting each other. Spectroscopic binaries are often too close together to be resolved visually, making spectroscopy a crucial tool for their detection.
Mu Draconis is a binary star - so which one?
A binary star can produce a nova when one star in the binary system accretes material from its companion, causing a sudden increase in nuclear reactions and a release of energy that leads to a temporary brightening of the system. This can occur when the accreted material ignites on the surface of the star in a runaway nuclear reaction.
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.
do you mean a purple star?? then the answer would be no!! If you mean is it possible that there is a red and blue Binary star system, where one orbits the other. Then the answer would have to be yes as there are no rules governing how a binary system is formed
