Dwarf Our Sun! An average sized star
13
The Sun is using losing 4 billion kilograms
of mass a second as four hydrogen nuclei are
converted to a single helium one, this loss in
mass provides the energy for the Sun to shine.
(Mass and energy are equivalent, as shown by
Einstein's famous formula Emc2). Large though
it sounds, this mass loss is actually
insignificant compared to the Sun's total mass.
The Sun's total mass is 2 x 1030 (or 2 nonillion)
kilograms. Another way of looking at the Sun's
mass loss is to consider how long it would take
for it to "evaporate" at its current rate of mass
loss it would take 14 trillion years. (Remember
that the Universe is only about 12 billion years
old.)

Dwarf -Average size star -93 million miles from
earth -stars vary in size, color, and
age -radiation is in the visible spectrum -some
larger burn quicker, some smaller and fainter

24
Giants! -Has depleted much of the fuel at the
core -Fusion continues, outward pressure
decreases, star begins to collapse -fusion of
outer layers, rapid expansion -outer layers cools
as it expands (red temperature)

White Dwarf
31
-Very little H or He energy available for the Red
Giant so it changes into a WHITE DWARF
STAR -Gravity causes the core to collapse
inwards -Leaves a hot, dense core of matter
-Hot in temperature but the star is dim in
brightness due to its decrease in size

Dead Star eventually the white dwarf will cool
and stop giving off light -may take billions
of years to cool
