Pictures of a nuthatch?

This small bird has been hanging out near our house.

Might be a nuthatch, or a northern downy woodpecker.

Thinking about carbon detonation in white dwarf stars (Type IA supernova)

I was reading about white dwarf stars because I've been very interested in neutron stars and I was wondering about something slightly less dense but really still incredibly dense.  While I was reading about that I learned about "Carbon Detonation" in which enough matter falls into a white dwarf star that it causes a runaway fusion reaction and explosion, which we've observed / classified astronomically as type IA supernova.  Here's some thoughts I've had about carbon detonation.

Installing pavers at the end of the driveway

I cut down a dead pine tree, took some live and time-lapse videos of it.
