We call them spider pulsars because like Earth's arachnids, they are 'eating' (more like ablating) their companions. 🕷️
We have two main types:
Black Widow Pulsars
Redback Pulsars
These are the nastiest of them all.

I wonder how many people would start a chat about the band Joy Division instead of pulsars 🙃

"I wanna be an astronomer who looks at pulsars"

It’s amazing (& wonderful) to me how shocked students are today when I relate the story of the discovery of pulsars & Dame Prof. Bell-Burnell’s exclusion from the Nobel. Even for students well aware of the reality of misogyny in our societies, they’re floored by what happened.
The kids are alright.

Great to see that Dame Prof. Jocelyn Bell Burnell is still being recognised and awarded for changing our view of the Universe!

Living around a pulsar would def. be scary for anyone not wearing SBF 3 million+ sunblock.
Pulsars emit a lot of high-energy radiation, so they would destroy atmospheres quickly.
They also blast out the powerful pulsar wind, which literally shreds their companions.

But, thankfully, pulsar planets are rare -- only a handful of pulsar planets are known to date.
We think this is because formation scenarios are rare and survival rates are low.
But we don't have firm answers yet.

Based on the rarity of pulsars, it sounds a lot like how the first exoplanets were found around them. I think this analogy could go far lol

the key notch positions on ddr4 and ddr5 dimms are governed by the U(1) group and are stable up to extremely high energies. scintillation traces from dimms emitted by pulsars seem to show ddr5 decaying into 1 ddr4 and 2 ddr3; some scientists think these are not dimm traces but lpcamm2

Also, as a note, considering eezo usually forms on planets being impacted by the gravity waves produced by supernovas, and usually are found in chunks of asteroids orbiting PULSARS, this makes the astrographic history of the Asari homeworld DEEPLY curious to me

A firefly-inspired model simulates alien radio pulses that stand out from pulsars while limiting energy use. The conceptual test focuses on recognition, not decoding. doi.org/hcqst2
Extraterrestrial detection inspired by firefly communications could distinguish alien signals from pulsars
When we think of extraterrestrial intelligence that might be out there among the stars, we tend to think of creatures not too unlike us, though maybe with gray skin, probably bald and with big black eyes.
