SOLVED: The Carina dwarf spheroidal galaxy has a velocity dispersion Ïƒ three times less than that at the center of the globular cluster Ï‰ Centauri, while Carina's core radius is 50 times greater. Use the virial theorem to show that Carina is about six times as massive as Ï‰ Centauri, so M/L must be 15 times larger.

The Sagittarius dwarf spheroidal galaxy is now about 20 kpc from the Galactic center: find the mass of the Milky Way within that radius, assuming that the rotation curve remains flat with V(R) ≈200 km s^-1. Show that this dwarf galaxy would need a mass of about 6 ×10^9 ℳ⊙ if stars 5 kpc from its center are to remain bound to it. Show that this requires ℳ / LV ∼70, which is much larger than the values listed in Table 4.2. | Numerade

One of the brightest stars in our galaxy, AG Carinae is a stellar monster fighting a tug-of-war between its outward radiation pressure and the inward pull of gravity to avoid self-destruction. Located 20,000 light-years away in our Milky Way Galaxy, this star is a few million years old and surrounded by an expanding shell of gas and dust nearly five light-years wide. This vast celestial structure formed from one or more massive eruptions around 10,000 years ago, blowing the stars' outer layers i
