This is inter_activity which should be done in a blog. I will ask a problem, we will discuss, and then solve it.
This one interested me so here it is:
A. The star Sirius (the brightest star in the sky) has a white dwarf companion. Sirius has a mass of about
2 Msun and it is still on the main sequence, while its companion is already a star corpse. Remember that
a white dwarf cant have a mass greater than 1.4 Msun. (Chandrasekhar limit http://en.wikipedia.org/wiki/Subrahmanyan_Chandrasekhar ). Assuming that they both formed on the same
time have a group discuss how Sirius could have a white dwarf companion. HINT: Was the initial mass of the white dwarf star more or lesser than Sirius?
