Hi, Dennis! Nice hobby you're taking up here....
Did the sun lose 95% of it's mass over several billion years? Because thats what it would take to slow it to it's current status.
Weren't you the one who mentioned figure skaters? They tend to not have intrinsic magnetic fields, and, if they do emit gas, do so on an intermittent basis - and lkely
very rarely when they are doing a spin. Stars, though, have magnetic fields and stellar winds.
Stars, therefore, have a mechanism of slowing their spin that isn't available to skaters: magnetic braking. They send out part of their mass and stay coupled to it. Skaters stick out part of their mass - their arms - and stay coupled to them.
Reading is a good hobby, too, Dennis.
