A new star!
Here are some interesting facts about new stars:
What is a new star? A new star is a star that has recently formed from a giant molecular cloud of gas and dust. This process is called star formation.
How are new stars formed? New stars are formed when a giant molecular cloud collapses under its own gravity, causing the gas and dust to heat up and eventually ignite into a star. This process can take millions of years.
Types of new stars There are several types of new stars, including:
- Protostars: These are stars that are still in the process of forming and are surrounded by a disk of gas and dust.
- T Tauri stars: These are young stars that are still contracting and cooling down after their formation.
- Herbig Ae/Be stars: These are intermediate-mass stars that are still in the process of forming and are surrounded by a disk of gas and dust.
Characteristics of new stars New stars are often characterized by:
- High luminosity: New stars are often very bright and can be thousands of times more luminous than the Sun.
- High temperature: New stars are often very hot, with surface temperatures of tens of thousands of degrees Celsius.
- Variable brightness: New stars can be variable, meaning their brightness can change over time.
Examples of new stars Some examples of new stars include:
- VY Canis Majoris: A red supergiant star that is one of the largest stars in the galaxy.
- R136a1: A massive star in the Large Magellanic Cloud that is one of the most massive stars known.
- HD 100546: A young star surrounded by a disk of gas and dust that is thought to be forming planets.
