PSR J0437-4715 ('J0437') is the closest MSP to Earth (511.93 +/- 0.35 light-years!)

It spins on its axis 173 times per second.

It has a white dwarf companion, and they orbit each other every 5.75 days. They are punching through the Galaxy, creating this bow shock structure.

Are millisecond Pulsars, nature's cosmic clocks, as stable as we once thought?

A new study by @rami.spaceaustralia.com has reported the discovery of two consecutive profile change events on PSR J0437-4715.

I'll wrap up this thread here, and say that the story is not over ... there is more to come and we are working on some exciting new results (paper 3 for my thesis!)

In the meantime, check out the reading:

Discovery of Two Consecutive Profile Change Events in the Millisecond Pulsar PSR J0437-4715
The closest and brightest millisecond pulsar (MSP), PSR J0437-4715, is a high-priority pulsar for precision timing experiments, including the Parkes Pulsar Timing Array (PPTA) project, where it is use...

Really nice write up from @drcarpineti.bsky.social for @iflscience.com on our new PSR J0437-4715 double profile change paper results!

Last year, astrophotgrapher Adam Block pointed a 24" telescope for a very long time at this.

And he took a colour H-alpha image of the bow shock around the pulsar! 🤯

This is EXTREMELY NEAT work and I think the first / only colour image of the J0437 bow shock.

Nice to see the Reardon et al. paper on scintillation arcs from the brightest millisecond pulsar PSR J0437-4715 now published in @natastron.nature.com!

www.nature.com/articles/s41...

Check this thread below for a brief explanation about this paper (when the pre-print came out a few months ago)

🔭
Arc curvature depends on distance, velocity, and orientation of scattering layers, so it can help probe these parameters.

This was analysed for PSR J0437-4715 (closest and brightest MSP to Earth) so they can model the pulsar-WD binary system ploughing through the ISM. Look at its bow-shock!
