Chandrashekhar limit for relativistic fermion gas

hi fellas, I have been working on Chandrashekhar limit, and I found a mass-radius relationship for the nonrelativistic fermi gases using this formula and i got the graph of this

R=((18pi)^(2/3))/10 *H^2/(GmM^(1/3) ) (0.5/n)^(5/3)

where H=(6.63*10^-34)/2pi
G=6.67*10^-11
m=9.11*10^-31
n=1.67*10^-27
M is the independent variable

but what changes should I make if i want to plot a mass-radius relationship for relativistic fermi gases? actually can you suggest me a reading for differentiating between relativistic and non relativistic fermi gases?
thanks

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

all i found out is the relation of radius vs mass for non relativistic gas, but is there any equation of R for non relativistic one where the radius goes to zero as mass goes to 1.44 ?
