Quick Black hole question

[kokain]

I am trying to figure something out and forgot the upper mas of a nuetron star. I remember (I think) that the upper mass of a white dwarf is 1.4suns but I can't remember the other.

The book I referenced for this is 9 years old now, but it theorizes 2 solar masses for a neutron star.

Thank you, that sounds right.
