Giant planets form beyond the frost line, where the equilibrium temperature is 150 K. The most common type of star that produces energy by nuclear fusion is a red dwarf star. A typical red dwarf star has a radius that is 0.5 times the solar radius, and a surface temperature that is 3600 K.

What is the distance to the frost line for a red dwarf star, in AU?

Assume the albedo is 0 for the planetesimals.

Problem 1: The core of the Sun has a temperature of 1.5 × 107 K, while the surface of the Sun has a temperature of 4910 K (which varies over the surface, with the sunspots being cooler). Treat the core of the Sun and the surface of the Sun as two large reservoirs connected by the solar interior. Nuclear fusion processes in the core produce 3.8 × 1026 J every second. Assume that 100% of this energy is transferred from...
