The Fate of the Stars

Student Research

Research Slide 1:

- What is it?

- Which stars go through this (the mass of the stars that

go through this)?

- Explain the star’s life cycle up to this point (see next

slide).

Slide 2: 4-5 Interesting Facts about your topic

Slide 3: Picture of the event

Each presentation will be ~ 5 min

the birth of a star & Nebulae What are they?

- A “Nebula” is a cloud of dust, hydrogen, helium, and other ionized gases- The birth of a star is when the components of a nebula bind to form a

small star, socalled “protostar”

The stars life cycle up to this point.

- A star begins to form from the materials in a nebula when gravity pulls chunks of gas and dust together which creates an early phase of a star called a “protostar.” this process takes approximately 10 million years.

Nebula: the birth of a star Interesting Facts:

- A new star(protostar) does not shine- A star is a loose mass of cold dust and gases - Thermonuclear fusion produces a star’s energy- Nebulae are often referred to as star nurseries of the

universe because stars often form inside of a Nebulae.- Protostar starts to glow and sends out electromagnetic

waves like how the sun creates radiation the keep Earth warm

Sweet superior super cool awesome fantastic astounding terrific fabulous astonishing breathtaking mind-boggling pictures of the “Birth of a Star” and “Nebula”

Neutron StarNeutron Stars are: City-sized celestial objects with a mass about 1.4 times that of the sun. They are therefore extremely dense.

Only very massive stars can become neutron stars.

Neutron stars are the result of Red Supergiants going supernova and forming because of the gravitational collapse of those massive stars.

Neutron StarOne teaspoon of a neutron star would weigh a billion tons.

Neutron stars can spin 43 thousand times a minute

In the first few seconds after a neutron star is formed, the energy leaving in neutrinos is equal to the total amount of light emitted by all the stars in the o. Universe

It is speculated that if life existed on neutron stars, it would be 2 dimensional

Neutron stars can be 10 times hotter than the sun

Black hole: Summary❖ A black hole is a place in space with no light that is so

dense that it absorbs everything in its vicinity using gravity.

❖ Only stars with the huge mass of over three times the mass of the sun go through the process to become black holes

❖ ANYTHING can get absorbed by black holes❖ A massive star is created from a stellar nebula which

then ages into a red supergiant which eventually explodes into a supernova. When a supernova become large enough, it gravity becomes strong enough to pull it back onto itself to become a neutron star. A black hole is created when the particles of a neutron star collapse inwards.

Black hole: FACTS❖ Stellar, miniature, and supermassive are the three types

of black holes

❖ The outer event horizon, inner event horizon and the

singularity are the three layers of a black hole

❖ The first black hole was discovered in 1916 by Karl

Schwarzschild, a German physicist and astronomer

❖ The term black hole was coined by an American man named

John Wheeler
