Why is the common envelope ejected in some accretor-donor systems?
As an example, let us consider a binary system of a neutron star and an evolved star (e.g. red giant) that has expanded, filled its roche lobe, and started the mass transfer onto the neutron star.

How to calculate the corotation radius?
I am studying this paper:
P.Ghosh & F.K.Lamb, APJ, 232, pag.259 (1979)
I do not understand how the authors calculate the corotation radius, $r_{co}$, where the matter of the disk has the same ...

Neutron Star LMXB Accretion Spin-Up Estimation
I've been asked to estimate how much mass a neutron star in a low mass X-ray binary would have to accrete in order to be spun up to ~300 Hz. I found the conservation formula
$\frac{d(I\omega)}{dt} = \...

Accretion neutron star; mass gain 0.8m?
My textbook on Astrophysics says the following about accretion (translation):
Assume we have a particle with mass $m$ that falls on a neutron star; $R\approx 10$ km, $M\approx 1.4M_{\text{sun}}$, ...
