How long does a Nebula last?
10,000 years
What does the Protostar evolve into
The Main sequence.
what is the size of a Protostar
10^10 km
What is the temperature of a Protostar
10,000 Kelvin
What is the elemental composition of a Protostar
Hydrogen and helium gas
How long does the Protostar stage last
What does a main sequence star turn into
A red giant or a red super giant
What is the mass of a main sequence star.
Ranges from the suns size all the way to 200 times its size.
In this stage the stars tempaure is at about 3000 K
Main Sequence Star
What 2 elements make up a main sequence star
Hydrogen and Helium
How long does a main sequence last
10 billion years
What do the Dwarf stars turn into?
Supernova or Black hole
What is the mass of the dwarf stars?
About the same as our sun.
What is the Temp of the dwarf stars?
100,000 kelvin
What elements make up a dwarf star?
Helium, Carbon, Oxygen.
How long do dwarf stars last?
What do Supernovas and Black holes turn into?
Supernovas turn into either a black hole or a neutron star. Black holes are the final stage of a star.
What is the diameter of a Supernova and Black Hole?
Supernovas can reach a diameter of several light years across. Black Holes are usually several million miles across.
What is the temperature of a Supernova and a Black Hole?
Black Holes are zero Kelvin. Supernovas are 6,000,000,000 degrees Kelvin.
What elements make up a Supernova? A Black Hole?
A supernova forms Hydrogen, Helium, Carbon, Silicon, Nitrogen, Iron, Oxygen, Neon, and Tennessine. The gravity in a Black Hole is too strong for there to be elements there.
How long does a Black Hole last? A Supernova?
A black hole last around 10^100 years. A supernova lasts usually several weeks to a few months.
