The figure above shows the light-curve obtained from continuous monitoring of the flux received from a star. Assuming that the dips arise because a planet orbiting the star passes between it and the observer once per orbit, estimate the orbital period (in days), the orbital semi-major axis (in Astronomical Units), and the physical radius of the planet (in units of the Earth’s radius). The star has a mass of 1.47 M⊙ and a radius of 1.84 R⊙.

where symbols have their usual meanings. Using the result that the central pressure in
a star, of radius R and uniform density, under gravitational attraction is given by Pc =
Gp² R², derive an expression for the radius Rwd of a white dwarf in terms of its mass M,
in the case of nonrelativistic electron degeneracy.
Using your result, briefly discuss the limitations of your expression for the radius, in the
context of white dwarfs of increasing mass.

helium nuclei and electrons. Show that the internal thermal energy of the ions alone is

Consider a spherical blackbody of constant temperature and mass M whose surface lies at
radial coordinater = R. An observer located at the surface of the sphere and a distant observer
both measure the blackbody radiation given off by the sphere. If the observer at the surface of
the sphere measures the luminosity of the blackbody to be L, use the gravitational time dilation
formula, to show that the observer at infinity measures.

- (Astronomy) PSR1913+16 Problem III. As the shape of the graph shown is not skewed, the orbit can be assumed circular. Also assume the system is viewed edge-on (that is, the orbital system is not inclined to the observer). Using these assumptions, the maximum radial velocities, and the orbital period T = 7.75 hours, find the orbital radii of the stars from the center of mass. (Hints: The figures below may be helpful. Use v = 2πr/P, where v is velocity, P is period, and r is radius.
