i've done a little research on whether tidally locked planets can support life and i understand there is a 'twilight zone' but would such a slow spinning planet even be able to produce a strong enough magnetosphere to keep its atmosphere from stripping away? thanks :)
Tidally-locked worlds are kinda weird, and it’s mostly up-in-the-air as to whether such a planet could have live. I’ve answered a question about the habitability of them, and it seems that some of them might, possibly be able to support life.
A planet’s magnetosphere is generated by it’s rotating metallic core. It’s possible for the crust to rotate at a different rate and speed as the metallic core. Indeed, Earth’s metallic core even has different parts rotating differently.
So, even if a tidally-locked world is rotating slowly (it rotates once as it makes one orbit), it would still be possible for it to have a magnetosphere.
Which is a good thing. Radiation can be icky to living organisms.
