What causes the radio pulses of a pulsar?
a. the star vibrates.
b. as the star spins, beams of radio radiation from it sweep through space. if one of these beams points toward the earth, we observe a pulse.
c. the star undergoes nuclear explosions that generate radio emission.
d. the star's dark orbiting companion periodically eclipses the radio waves emitted by the main star.
e. a black hole near the star absorbs energy from it and re-emits it as radio pulses.
