ASTR 3730: Astrophysics 1 Problem Set #3 Due in class Friday 17th
 

Summary: ASTR 3730: Astrophysics 1 Problem Set #3
Due in class Friday 17th
October
1) The table below lists the apparent magnitude m, distance d (in pc), and
effective temperature Te for a small sample of stars [rest of question deleted...]
The HR diagram looks like:
The three giants (upper right corner) are g Cygni, g Andromedae, and
Antares. The three white dwarfs are Sirius B, Procyon B, and L145-141. All
the other stars are main sequence stars.
2) A very simple model for a star is obtained by assuming that the density
decreases linearly with radius:

r(r) = rc 1-
r
R




where rc is the central density. If the star has a radius R and a total mass M, use
