Stars emit radiation whose spectrum is very similar to that of a blackbody. Imagine two stars identical in size, each of which is at the same distance from us. One of the stars appears reddish in color, while the other one looks distinctly bluish. Based on this information, what can you say about the relative temperatures of the two stars? Which is the hotter? The relative temperature of a star that is red in color is higher than that of...

(1) a. Show explicitly that for very massive stars (opacity dominated by Thompson scattering, pressure from radiation) that luminosity is proportional to mass. b. Show explicitly that for moderately massive stars (opacity dominated by Thompson scattering, pressure from gas) that luminosity is proportional to mass cubed.

Chapter 14 The Size of Stars 10 of 11 Constants The hot glowing surfaces of stars emit energy in the form of electromagnetic radiation. It is a good approximation to assume that the emissivity e is equal to 1 for these surfaces. Part A Find the radius RRigel of the star Rigel, the bright blue star in the constellation Orion that radiates energy at a rate of 2.7×1031W and has a surface temperature of 11,000 K. Assume that the star...

Neutron stars are one of the possible “final states” of a star. The idea is that for a sufficiently massive star, the gravitational pressure is enough to overcome the outward pressure (that comes from essentially the Pauli exclusion principle) that keeps fermions from coinciding with each other. Part A) According to quantum statistics, the OUTWARD pressure of a (neutron) fermionic gas is given by P=[(3.9?^2)/(2m)](N/V)^(5/3), where m is the mass of a neutron, and N/V is the number density of...
