Recycling in the Universe Alyssa A. Goodman Department of Astronomy Harvard University

Recycling in the Universe Molecular Clouds Stars Mass Loss

Fluctuations about 300,000 years after the Big Bang led to "Structure Formation"

Pretty young galaxies

"Star Formation"

Star "Death": Interstellar Recycling Plants Mass=100 x Sun

Distribution of Recycling Plants Relative Number of Stars Mass [M Sun ] e.g. for every "Sun" there are 22 stars with mass 10x smaller than the Sun's The "Initial Mass Function" (IMF)The Hertzprung-Russell Diagram 100

Output of Recycling Plants The Hertzprung-Russell Diagram Supernova, then neutron star/pulsar or black hole Red giant then white dwarf Long-lived brown dwarfs "Styrofoam" Good recyclables. Red-giant wind main dust injection in ISM. Spectacular contribution, and collection. Explosion injects, and "sweeps up" interstellar material.

A "Supernova " Recycling Plant

Swept-up Gas:The Next Generation

“Star and Planet Formation” Giant Molecular Clouds "Cores" and Outflows Jets and Disks Solar System Formation

"Dark" Clouds

(Unusual?) Stellar Nursery in the Eagle Nebula

Star Formation Caused by A Galaxy Collision (a.k.a. igniting the trash)

Output of Recycling Plants The Hertzprung-Russell Diagram Supernova, then neutron star/pulsar or black hole Red giant then white dwarf Long-lived brown dwarfs "Styrofoam" Good recyclables. Red-giant wind main dust injection in ISM. Spectacular contribution, and collection. Explosion injects, and "sweeps up" interstellar material.

"Excess Gas?" Post-red-giant planetary nebula
