•Question 2 (1
point) We believe that we receive hundreds of pulses per second from so-called
"millisecond pulsars"
because the neutron star emitting them:
•a.Is
spinning hundreds of times per second.
•b.Is actually pulsing (due to thermal instabilities)
and changing its size
hundreds of times per second.
•c.Is in a binary system orbiting another star
hundreds of times per second.
•d.Is seen through a certain kind of nebula that
causes "scintillation".
•e.Is surrounded by an accretion disk which has
material orbiting the star
hundreds of times per second.
•
•According
to the “lighthouse” model of pulsars, we’re seeing the neutron star’s magnetic north (or south)
pole once per spin, and the rotation axis and the magnetic axis are offset.
