Introduction

• Supernova: The death of a star.
• Presenter: Dr. Binox

Types of Stars

• Blue Giant
• Red Giant
• Red Super Giant
• G2V Yellow Dwarf (our Sun)

What is a Supernova?

• A massive explosion at the end of a star's life cycle
• Result of changes in the core of a star

Causes of Supernova

Type 1: Binary Star Systems

• Binary Star Systems: Stars orbiting around a common center of mass
• Process: A carbon-oxygen white dwarf takes matter from its partner star
• Result: Accumulation of matter causes the white dwarf to explode

Type 2: Single Star's Lifetime

• Process: Star runs out of nuclear fuel causing mass to flow into the core
• Core Collapse: Center becomes too heavy, cannot withstand gravitational force
• Result: Matter and radiation blast out, causing a supernova

Stars that Don't End in Supernova

• Not all stars end with a supernova
• Our Sun does not have enough mass for a supernova

Importance of Supernovae

• Short Duration: Burns for only a short period
• **Scientific Insights: **Tells scientists about an expanding universe
• Element Spread: Plays a role in spreading elements across the universe
  • New stars and planets form from these elements
• Fact: Many elements on Earth are made in the core of stars
