A bit hard to follow, when all the clips were run in parallel side by side and that fast.

Agreed. I had to watch it a couple of times and concentrate on particular frames. Sometimes a serial interface is better than parallel? :)

I found it a bit tough to watch as well. But I am surprised by the conclusion.

Yes, that is a shocker. I'm wondering if the connection is the difference in internal density distribution which is due to how thermal energy is transported to the surface of the star?

Really low mass stars are convective throughout with no radiation zone. Stars of solar mass have a radiative core and a convective envelope. High mass stars have a convective core and a radiative envelope. The stars between the really low mass and solar mass are a mess with the core transitioning to radiative transport. The density distribution depends on the mode of energy transport which in turn depends on the temperatures involve. The convective envelope of solar type stars is because of the partial ionization of hydrogen and helium. At higher temperatures and masses, they are fully ionized and so convection doesn't happen.

That's all I have.

kind of surprising- wish they said which stats had higher density and why it made stars fall apart-
