A brown dwarf star called CoD-33°7795B has a luminosity of 0.0025 ?⨀. It has a relatively high surface temperature of 2559 K, which suggests that it is very young and has not had time to cool down by emitting radiation. (a) What is this brown dwarf’s spectral class? (b) Find the radius of this brown dwarf. Express your answer in terms of the Sun’s radius and in kilometres. (c) How does this compare to the radius of Jupiter? Is the name “dwarf” justified?

A certain red giant star has a luminosity of 100,000 times that of the Sun and is located 600 light-years from Earth. If the apparent magnitude of the star is observed to be m=0, calculate the rate of interstellar extinction in the direction of the star. If someone could show me step by step how to solve this I would be appreciative.

For a relatively weak gravitational field, such as that of a planet or an ordinary star, the following formula tells us the fractional amount of gravitational time dilation at a distance r from the center of an object of mass Mobject: 1c2×GMobjectr (G=6.67×10?11m3/(kg×s2); c=3×108m/s.) For example, while 1 hour passes in deep space far from the object, the amount of time that passes at a distance r is 1 hour minus 1 hour multiplied by the factor above. (This formula...
