Lecture 24 March 13, 2017
Doppler shift in Binary Stars
- In regular stars, detect binary orbital motion from Doppler shift of wavelengths of absorption
lines
- Moving towards you blue shifted
- Moving away from you red shifted
Doppler Shift
-
- Radial velocity twice as large half the mass
Doppler shit in binary pulsars
- Apparent pulse period in binary system changes due to Doppler shift
- Longer period = red shift
- Short period = blue shift
- Can study binary motion with exquisite precision
- Top of peaks longest period exactly away from you
o Vice versa is also true
Pulsar in an eccentric binary orbit
- Enables exquisitely precise dynamical measurements
-
- This shape from keplers law slow then fast
Doppler shift in pulsar

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
