Young stars, still in their birth nebulae. Aging supergiant. Stars are not eternal - they are born, live a finite life time, and die. ASTR170.
High-mass stars live for one million to tens of millions of years while low-mass stars, like our Sun, live for tens of millions to trillions of years. MASS. TIME. Composition is > 98% hydrogen and helium. 1/3 of the hydrogen is converted to helium. MAIN SEQUENCE. Massive stars are capable of producing heavier elements, like

Life Cycle of Stars. Purpose. This activity enables students to demonstrate the life cycles of different types of stars, thereby illustrating the rarity of black hole-producing stars. Objectives. • Students will understand how and when black holes form. • Students will be able to describe the Sun as a star. • Students will be able to
A star's life begins • The smaller a star is the longer it will live. – Larger stars have more fuel, but they have to burn (fuse) it faster in order to maintain equilibrium. – Because fusion occurs at a faster rate in massive stars, large stars use all their fuel in a shorter length of time. – SoA smaller star has less fuel, but its rate of.
The Life Cycles of Stars. • Planetary nebula. • Fusion. • Red Giant. • White Dwarf. • Binary Star. • Spectral Class. • H-R Diagram. • Supernova. • Core Bounce. • Nova. • Main Sequence. • Luminosity
The Sun is our local star. • The other stars are outside our solar system. • There are huge distances between objects in the universe. NOW, you will learn. • How stars are classified. • How stars form and change. KEY CONCEPT. Stars change over their life cycles. EXPLORE Characteristics of Stars. How does distance affect
Mar 16, 2009 Gravity causes dense cores in molecular clouds to collapse. •. Collapsing cores heat up. •. When core gets hot enough, fusion begins and stops the shrinking. •. New star achieves long-lasting state of balance. •. Sometimes protostars can drive an outflow (jets) of material. •. Protostars rotate rapidly, and
