How Stars Form
____________ ______ are the main structures of mass that the star is created by.
Interstellar Cloud
Are adult star bigger than baby stars?
No, they are much smallar than baby stars.
How do stars die?
when a star runs out of hydrogen fuel, it begins to contract under its own waight because of gravity and will eventually either explode of fade.
How do high mass stars die?
unlike low mass stars, they will actually blow up creating a supernovae
What is the largest known star?
UY Scuti
If the cloud can cool sufficiently, ______ will always cause a contraction and subsequent collapse
Gravity
Are stars' age determined by mass?
Yes, the larger the mass, the less longer it will live, the smaller the mass the longer it will live (exluding baby stars).
How do low mass stars die?
unlike most big stars, Low mass stars will shed their outer layer and it will spread to the interstellar medium
how old until high mass stars die?
they don't really last long so they live to around a few million years, usually less than 10 million.
What is the smallest known star?
EBLM J0555-57
Star formations can be assisted by _________ when it slowly begins it's process.
Supernovae
What are the shapes of a standard star?
Stars for the most part are big round masses of burning gass
how do medium mass stars die?
Medium mass stars are no different than low mass stars besides that the mass is larger
Can a high mass star be dangerous when it explodes?
it depends on the distance but for the most part, no.
What is a star made of?
Very hot gas such as hydrogen or helium.
What if the collapsing cloud is to big?
The star being created will eventually blow itself up
What is a normal age for a adult star?
Between 1 to 10 million year old.
How old do medium/low mass stars live until death?
low mass stars can possibly live for over trillions of years while medium mass stars can live much shorter but over billons of years
what can an explosion from a high mass star create?
some explosions from high mass stars can create black holes
Which is hotter, blue stars, red stars, or white stars?
Blue stars are the hottest stars
What are the 3 steps to creating a star?
1. Initial collapse of an interstellar cloud
2. The Gravity makes the clouds into into clumps
3. The clumps collapse into a stars
what is a name for a adult star that is closest to earth
Our sun is a adult star and it's the closest one.
Which has a shorter lifespan a medium mass star or a low mass star? Why?
A low mass star has a longer lifespan because they burn off less energy than larger stars.
How big can high mass stars get to?
as long as the're 3 times biger than the sun.
how are stars' distance measured from earth?
in AU (Astronomical Units)
