comment Gross “temperature” of a globular cluster
While the concept of temperature might be of questionable usefulness in this case, you might find discussions about so-called "binary heating" to be interesting.

comment Has a stellar blackhole more mass than previously?
Just a small correction: The inward force compressing the matter is just gravity. The expulsion of matter outwards is a consequence of tapping into the gravitational potential energy.

comment Metal-rich star formation
Isn't the process of star formation sufficiently complex that it's possible that a single value for a maximum metallicity is impossible to compute?

comment Why is Heisenberg uncertainty principle not valid in waves in string?
Is $\mu$ as you've defined it really the mean value of $f(x)$? I would say that it's the mean value of $x$, if $f(x)$ is interpreted as a probability amplitude.
