Question 1

1.

Read chapter 14.1-3 Do you have any questions?

Question 2

2.

Draggable item		Corresponding Item

Question 3

3.

The type Ia supernova is the one where a white dwarf adds mass from its companion star and reaches its limit until it supernovas. These are really useful because they have a distinct signature spectrum, and because this type of supernova is always exactly the same. Why are they exactly the same?

Question 4

4.

When there is a redshift in light, the doppler effect tells us this means that

Question 5

5.

Gravitational redshift is similar and different from doppler shift redshift. Explain how.

Question 6

6.

how do you think the gravitational redshift is related the fact that radiation cannot escape a black hole?

Question 7

7.

Ok, watch this video on black holes, and this is a niiiiice short flipped classroom because you

Question 8

Pulsar

A rotating disk of gas, dust, and other matter that forms around massive objects in space due to gravity pulling material toward it

Degeneracy pressure

The maximum mass (about 1.4 times the mass of our Sun) that a white dwarf star can have before it collapses under its own gravity

Neutron star: 

A quantum mechanical force that prevents certain types of stars from collapsing, created by electrons or neutrons being squeezed too close together

Supernova: 

An extremely dense stellar remnant composed almost entirely of neutrons, formed when a massive star explodes and its core collapses

Accretion disk: 

A powerful explosion that occurs at the end of a massive star's life, briefly outshining entire galaxies and spreading heavy elements into space

Chandrasekhar limit: 

A rapidly rotating neutron star that emits regular pulses of radiation from its magnetic poles, acting like a cosmic lighthouse

what is a white dwarf

what happens to a white dwarf in a binary star system that can lead to a type 1a supernova

what happens during a supernova

how does a black hole form

what is gravitational redshift?

what is the even horizon

what is the schwarzschild radius

I've got this

im fuzzy

so confused
