Exploring Pulsars: Radio Pulses from Neutron Stars

Learn about pulsars, remnants of supernova explosions, with rapidly rotating structures and strong magnetic fields emitting beams of radio energy. Detect and find distances using pulsar timing techniques, observed with radio telescopes on Earth. Follow the procedure in the CLEA manual to calculate distances accurately using radio pulses. Understand distance equations and solve problems step by step.

Presentation Transcript

  1. Announcements

  2. Radio Astronomy of Pulsars Tiffany Pewett pewett@chara.gsu.edu

  3. Pulsars • Remnants from supernova explosions (neutron stars). • Rapidly rotating. • Strong magnetic fields. • Beams of radio energy emitted at the magnetic poles.

  4. Pulsars

  5. Pulsar Structure

  6. Pulsar Detection • Initially thought to be a signal from another planet. • Observed using radio telescopes on Earth. • Detected radio “pulses”

  7. Radio Pulses

  8. Finding Distances • Pulsars provide distance using “pulsar timing” • Pulses arrive at different times when observed in different frequencies. • This delay provides the distance.

  9. Finding Distances

  10. Procedure • Carefully read the CLEA manual. • Fully answer ALL questions and show your work. • Don’t forget to use units, typically seconds (sec) • For last part, use same frequencies (much easier). • Do NOT record your data!

  11. Distance Equations • T1=Tf1, so if f1=600, then T1=T600 • Same goes for T2(=Tf2) • D=(T2-T1)÷(124.5×((1/f2)2-(1/f1)2)) • Show ALL work and fully answer all questions!
