    Graduate Chandrashekhar limit for relativistic fermion gas

    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 ?

    Graduate Mass radius relationship for SIRIUS B

    dear Chronos, I actually visited that page earlier, for relativistic fermi gas they derived the relation to be 1=M^(-1/3) , so radius actually cancels out from both sides. so how do they plot that graph where radius is zero when mass goes to 1.44? i didnt get any expression for the graph..can...

    Graduate Mass radius relationship for SIRIUS B

    But the relativistic fermi gas plot is different than the non relativistic, i want to know how do they get this graph?

    Graduate Mass radius relationship for SIRIUS B

    hi guys, I have been doing a research on white dwarf stars and chanrashekhar limit. I need to plot a graph for the mass-radius relationship of the dwarfs. from the equalization of the hydrostatic equilibrium pressure and the electron degeneracy pressure I found out the radius -mass relationship...

    Graduate 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...

    Undergrad Generating the function from given coordinates and slopes

    i got the curve to be sort of a straight line. I might have worked out with it to get a y=mx curve, but i m looking for a more accurate function because my straight line is slightly deviating from its path, not exponential though..actually i need to know if there is any mathematical manual...

    Undergrad Generating the function from given coordinates and slopes

    hi fellas, i have been given a graph from which i can extract the coordinates and the slopes but all i need is to generate the function this graph represents. can you suggest me any manual procedure to do this mathematically or do i have to use software to generate polynomial functions? if...

    Graduate How Does Velocity Affect Time, Length, and Mass in Special Relativity?

    i have the basic question of special relativity why time , length and mass is a function of velocity here? i may know the mathematical interpretation of special relativity but i did not understand it physically how time can depend on these parameters. some please make me clear on this issue regards

    Undergrad What is the Electric Field Inside and Outside of a Sphere?

    hi guys, i have been following griffith's book on electrodynamics and i m stuck with probably one of the basic concepts on electric field. i did not understand what would be the electric field, 1) inside and 2)outside of a sphere with radius R ? also there are two problems which deals with...

    Undergrad Is there any relation between orbital motion and spin motion?

    hi guys, i have a question about the orbit-spin relationship of the celestial objects. for example in our solar system i understand the orbital period becomes lengthy for the planets more distant than the sun, it's logical, but what happens with their spinning motion..? i don't understand why...

    Graduate How to apply ladder operators?

    The total energy of a particle in a harmonic oscillator is found to be 5/2 ~!. To change the energy, if i applied the lowering operator 4 times and then the raising operator 1 times successively. What will be the new total energy? i want the calculation please

    Graduate How to get wavelength of the wave function?

    A particle in the infi nite square well potential is found at the 3-rd excited state. What is the wavelength of the wave function of the particle? this is a mcq from my faculty who denoted the correct answer to be 2/3 a ...how to get that ?
