Yea true. The other issue is radiation from the host star. But, underwater warm oceans with life? Id say very possible.

One good thing about Red Dwarfs is time. They are in the main sequence for 10s-100s of billions of years, a lot of time for evolution.

The article did mention that the star was particularly stable with no flares in the years that it was observed.

Is there any buildup to a solar flare, or is it just instant lethal radiation? Water's great shielding and aquatic life would still be able to turn amphibious, as long as dry land isn't certain death.

They're known for being stable, but I'm not sure about how flares work.

According to a recent study, red dwarf flares generally originate away from the equatorial plane, so the frequency of impact may be low on astronomic timescales.
