temperature/ color/ white dwarfs
what is temperature measured in
measured in kelvin
stars are measured in what
Diameter or Radius
what is luminosity
How bright a star actually is
astronomers group stars together that
have similar properties
giant stars age
old and near the end of there life cycle
what determines color
temperature
1 km=
11 football fields
what is Apparent magnitude (brightness)
How bright the star appears to be based off its distance from earth
The Hertzsprung Russell Diagram organizes the stars into a chart
using a star’s Luminosity and Temperature
giant stars helium ad mass
running out of helium and not alot of mass
what are the colors from cool to hot
red, orange, yellow, white ,blue
main sequence stars age
young to middle age
the farther from earth the star is
the dimmer they appear to be
giant stars blue and red
blue giants: hotter, and brighter
red giants: cooler, and dimmer
dwarf age
remnant (what is left) of dying star
mass main sequence stars
have a lot of mass because of gasses in them
super giants age
also in the end of the star life cycle
dwarf helium
no more helium left
super giants mass
have alot of mass
