Types of Stars
Dwarf Stars
- Yellow Dwarf Star
- Small, main sequence star.
- It is a g-type on the spectral class
- It has a lifespan of 10 billion years
- Will eventually turn into a red giant star
- Red Dwarf Star
- The most common type of star
- Smallest of all of the stars
- Burns at a lower temperature
- Dimmer than any other star
- Has a lifespan of trillions of years
- Will eventually become a white dwarf star
- White Dwarf Star
- Basically a dead husk of a star
- Very small
Giant Stars
- Red Giant Star
- 100 million to 1 billion kilometers in diameter.
- A cooler star, with temperature ranging from 2,200 to 3,200 degrees Celsius.
- Lifespan as a Red Giant: a few thousand to a billion years
- Smaller stars become white dwarfs, while larger ones become a supernova.
- Blue Giant Star
- Very Hot
- Very bright
- Short Lifespan (10,000-100,000 years)
- Becomes a supernova
SUpergiants
- Much larger than a giant star
- Thousands of times hotter than a giant star
- Short lifespan because of this (10-50 million years)
binary Stars
- Two stars orbiting a common center of mass
- Binaries that are close can actually transfer mass to one another
- Stars that are binary actually help scientists determine a star’s mass
