We have not been able to extract from their work a single definitive analytic formula to compare with the Salpeter result, or with the various results of the rest of the heterodox “screening” literature.

Neutron Degeneracy Pressure

This results in cooler temperatures at the core, causing the thermal pressure to decrease. The white dwa ...

... Chondrites are meteorites that contain millimeter-sized objects called chondrules. In the 1960s and 70s, there was great hope that chondrules formed directly from the cloud of gas and dust that surrounded the Sun as it was still forming.
