Study Notes
Nebula and Star Formation
- A nebula is a cloud of dust and gas in space where protostars are formed.
- The birth of a star is triggered by a disturbance in a nebula, causing its center to collapse under gravitational forces.
Protostar Development
- The development from protostar to adult star can take approximately 50 million years.
Nuclear Fusion
- Stars are formed when hydrogen atoms bond through a process known as nuclear fusion.
Star Types and Longevity
- Red dwarfs consume energy more slowly than giant stars and have a longer lifespan.
The Sun
- The sun is classified as an average-sized star.
Red Dwarf Lifecycle
- The death of a red dwarf occurs when hydrogen depletes in its core, leading to cooling and transformation into a white dwarf.
Supernova Events
- A supernova does not occur with every star's death; it is a specific and explosive endpoint for certain stars.
Black Holes
- Black holes are characterized by their exceptionally strong gravitational pull, affecting surrounding matter.
Neutron Stars
- Neutron stars are formed through the combination of protons and electrons, resulting in a dense stellar remnant.
