12b - Star Death

Why is it that every collapsing star does not end up as a black hole? What happens to Red Dwarf stars when they reach the end of their lives? What will happen to our Sun, a small yellow star?

Answer #1

As was told by chandrashekar only stars with mass above Chandra limit will become black hole.since only then the gravitational force due to mass will overcome the repulsion force due to nucleons and hence will collapsed in itself thus forming a black hole. Red dwarfs die when they burn all their fuel and that they turn into white dwarfs which further loses all of its hear and becomes a black dwarf. Our sun will turn to red giant then planetary nebula then white dwarf and finally will become black dwarf since it's mass is below Chandra limit.

The globular cluster doesn't have enough gravity to capture any stars more massive than our sun yet. The globular cluster is younger than the typical lifetime of a star like our Sun. The globular cluster is older than the typical lifetime of a star like our...

    10. At the end of the Sun’s life it will use up the hydrogen and helium in its core and become a white dwarf. The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density...

    Before leaving Alpha Centauri, you change from the shuttle to a light speed interstellar cruiser and head out deep into the galaxy to visit another binary star system - but this one is composed of dead stars! To occupy your waking travel time by reading about this star system in the "Outer Space Tourbook": Stars spend most of their lifetimes undergoing nuclear fusion in their cores, which is why they give off so much light. However, when the material necessary...

    Please answer these questions in detail. What does a “good death” mean to you? Why? What does a “bad death” mean to you? Why? Our society is known for its tendency to deny the inevitability of death and dying. How do you think this tendency has affected our public policy decisions about healthcare spending and utilization? Our current healthcare system is known for its “perverse incentives” – i.e., financial incentives, usually through reimbursement schemes, embedded in a system that work...
