    Default M dwarf CMEs hostile to life



    Are Stellar Storms Bad News for M-Dwarf Planets?

    thi article lays it out pretty well except that it doesn't explain WHY M dwarfs have more violent flare activity than solar type stars. in case you are wondering the internal structure of M dwarfs is dominated by regions of convection. the sunlike stars have more of their interior transporting energy radiatively, without convection. convection drives that magnetic dynamos that creates the instabilities resulting in flares. i think that's it anyway.

    Looks like bad news to me. Given a strong enough planetary magnetic field though, can you imagine the auroras?

    The views would be pleasant, sure. The lead underwear might be annoying though...

    Another "Goldilocks" situation, not too close, not too far, not too hot, not too cold, etc. Of course our bias is based on our experience of life as we know it. So it's not surprising, our imagination of how life might be elsewhere could be hopelessly limited.

    With only one datum it is hard to say whether our imagination is limited or not. There is no data to justify either the view that our imagination is limited or the view that our imagination is all encompassing.

    Since there is speculation about exotic chemistries for life.....

    https://en.wikipedia.org/wiki/Hypoth...f_biochemistry

    ... it just might be that our imagination runs far beyond what is actually realized.

    We know little of the relevant data to make a judgment.
