Stars bolster Einstein’s theory

Astronomers have observed a dwarf star in the Musca constellation with a mass so great that it distorts space-time. Its companion, a pulsar, orbits the dwarf star in a rapid five-hour cycle. The white dwarf, though Earth-sized, is far denser. The pulsar, a supernova remnant, emits neutrons. The white dwarf's gravity and spin cause frame-dragging, affecting the pulsar's motion. This phenomenon, observed by Australian telescopes, supports Einstein's theory of general relativity.

What is the significance of the dwarf star's mass in relation to space and time?

Describe the relationship between the exotic pulsar and the dwarf star.

How does the white dwarf's gravity affect the pulsar's motion?

Explain the concept of frame-dragging as it relates to the neutron star.

What evidence supports Einstein's theory of general relativity in relation to the pulsar?
