I'm trying to find the equilibrium size of a planetesimal which is made of a material whose density is pressure dependent. (quite a mouthful)(adsbygoogle = window.adsbygoogle || []).push({});

I have to solve this differential equation:

[tex]y(x^2y''+2xy')+2y^2+bxy'=ax^2y^3+(xy')^2+by[/tex]

where a and b are constants.
