Presentation transcript:

Heat Brightness cooler hotter brightest darkest Each star is represented by a dot. The position of the dot tells us two things about the star: its brightness (luminosity) and its temperature.

I N SOME VERSIONS OF THE HR D IAGRAM THE COLORS OF THE STARS ARE WRITTEN ACROSS IN THE ORDER OF : BLUE OR BLUE - WHITE, WHITE, YELLOW, RED - ORANGE, RED. B LUE IS THE HOTTEST STAR AND RED IS THE COOLEST STAR. ( JUST LIKE FIRE !)

StatementTrue?False? A star with a luminosity of 0.01 solar units and a temperature of 40,000 Kelvin would be classified as a main sequence star. Super giants are brighter than red giants. White dwarfs are hotter and darker than a main-sequence star A star with a brightness of 110 solar units and a temperature of 2700 Kelvin would be classified as a super giant. Red giants have more luminosity than super giants.

StatementTrue?False? A star with a luminosity of 0.01 solar units and a temperature of 40,000 Kelvin would be classified as a main sequence star. X – White Dwarf Super giants are brighter than red giants. X White dwarfs are hotter and darker than a main-sequence star X A star with a brightness of 110 solar units and a temperature of 2700 Kelvin would be classified as a super giant. X – Red Giant Red giants have more luminosity than super giants. X
