Binary Pulsar Orbital periods.

[teroenza]

Hello,
I am doing a very brief presentation for school on gravitational radiation and wanted to include a figure for the orbital periods of binary pulsars. I can find the rotation rates of individual pulsars on Google but can't find a figure for orbital periods of binaries. This does not have to be exact, even order of magnitudes would work. I thought it would be interesting to say something along the lines of, "imagine these super dense objects, orbiting each other at rates of ~ XXXX."

Thank you

Thank you

From hours to day.

I just Googled 'list of known binary pulsars' and quickly found this. Most are hours to days as Nabeshin said.

Great, thank you both.
