Star Creation
All stars are born in this.
Stellar Nebula
Stars spend their STABLE life on the______ of the HR diagram
Main Sequence
What is the explosion of a large mas star called?
300 extra points if you steal something from Mr. Mathias' room and bring it back
Supernova
What are the three main sections you can see on an H-R Diagram?
300 extra points if you stand on your hands (can use wall as support)
White dwarfs, main sequence, giants
What color stars are the hottest?
100 extra points if you can roll your tongue
Blue
What is a stellar nebula? Why is it sometimes called a stellar nursery?
What size stars live longest?
300 extra points if you can sink a basketball shot outside FIRST try
Small-average stars
What happens at the end of an extremely massive stars life (what will it turn into)?
Black hole
What two things does an H-R diagram compare?
100 extra points if you beat me in rock paper scissor
Luminosity and temperature
How do stars look to us VS what do they actually look like?
Look small are HUGE
What force brings gas and dust together to form a star?
Extra 100 points if you dab
Gravity
What do all stars turn into when they leave the main sequence?
A variation of a red giant (massive, supermassive)
What are the three things that stars can become at the end of their lives?
Name the size with each for 200 extra points
White dwarf-small/average
Neutron star-large
Black hole-super large
Where is our star "the sun" on an H-R diagram? (which group)
100 extra if you can prove you did Mrs. Halpern's virtual day assignment
The Main Sequence
How far are stars from eachother even though they look very close?
many lightyears - 6 trillions of miles
How are white dwarfs created?
Death of an average mass star - core left behind
What are some things that can change over the lifetime of a star?
(name 3 - 100 extra if you can name 5)
Color, size, temperature, class, brightness, mass, radius
While large stars supernova, what do average stars explode into?
Planetary nebula
What are the three main sections of the HR diagram?
Red giants, main sequence, white dwarfs
Which objects in space have the largest gravitational pull? Why does our sun keep our solar system operational?
Larger Mass
Describe nuclear fusion and how it makes a star shine?
2 hydrogen atoms come together to form helium
What keeps a star stable? (think layers)
Balancing the inner core and outer layers (not running out of fuel)
What causes the death of a star?
Runs out of fuel - collapses- inner core remains and cannot support outer layers of the star
What is different about the X axis on H-R diagram compared to other graphs?
Starts with larger numbers and goes down (reversed)
What is the name of the star that is closest to us OTHER than our sun (4.3 lightyears / over 24 trillion miles away)
Proxima Centauri
