Star Constellations
Star constellations are to tell which star is
which
 Without a star constellations they will be
hard to identify
 Example: the Three stars you would see in
a straight line in winter are part of Orion

Mythology on Star Constellations

Canopus the lowest star to the Greeks
Ancient poets identified the Milky way as the road of the
gods
Libra the claws of the Scorpion
Babylonians and Greeks both identified five planets as
their gods
Pleiades was a seasonal sign to any civilization
The constellation figures of the northern hemisphere are
over 2000 years old.

There are 88 constellations recognize
Currently, 14 men and women, 9 birds, two insects, 19
land animals, 10 water creatures, two centaurs, one
head of hair, a serpent, a dragon, a flying horse, a river
and 29 inanimate objects
The ancient constellation-makers probably meant for
them to be symbolic, not literal, representations of their
favorite animals or fabled heroes, a kind of celestial Hall
of Fame

There are obsolete Constellation
Astronomers attempted to name them after patrons or
kings
These can be seen in antique star charts
Almost every civilization had star constellations
The big dipper is part of the Greek constellation the great

Astronomers said that there where fixed stars which are
permanent positioned in the sky
Stars Facts

Any star that changes is called a variable star they are
usually Bright
Stars can vary because intrinsic to the star itself
Eclipsing binaries is a system where two stars orbit are
inclined with each other so both stars will pass each
other occasionally
Pulsating variables stars are intrinsic they vary in
brightness and is due with a physical change in the star
Pulsating stars



In the case of pulsating variables this is due to the
periodic expansion and contraction of the surface layers
of the stars or it increase or decreases in size
periodically
Light and curves show us the interior process in the star
Cepheid light curves are distinctive and show a rapid rise
in brightness followed by a more gradual decline, shaped
like a shark fin

This is the best way to find the mass of a star
The sun Temperature



The sun is the most hottest star
temperature of 6,000°C (11,000°F) at the photosphere
Its solar energy temperature is(15,000,000° C;
27,000,000° F)

Chromosphere temperature 4,000°C (7,000°F)


The suns pressure is 340 billion times of earths air
pressure at sea level
A nuclear reaction can occur with protons and hydrogen
nuclei to fuse together
Its mass is expelled as energy because of convection
Every second 700 million tons of hydrogen is converted
to helium ash
The corona is the outer part of the sun

The sun is 4.6 billion years old
Has enough fuel to last another 5 billion years
The sun will fuse helium into heaver elements and begin
to swell up
It will finally become a red giant
Then collapse as a white dwarf
