When is a star formed?
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
Can a planet become a star through a process of stellar evolution?
Yes, a planet cannot become a star through stellar evolution. Stars are formed from collapsing clouds of gas and dust, while planets are formed from the leftover material in a star's protoplanetary disk.
How many years has the sun being burning?
It is estimated that the sun formed into a star about 4.57 billion years ago.
Do black holes and neutron stars have any connection?
Yes, both black holes and neutron stars are remnants of the death of massive stars. Neutron stars form when the core of a massive star collapses but does not produce a black hole. Black holes are formed when the core of a massive star collapses beyond the neutron star stage.
What is an Australian 1 Dollar star note?
A "Star note" is a bank note that is reprinted due to a problem with the printing process and the original note being spoiled and not subsequently issued for circulation. A "Star note" is identified by the last digit of the serial number being a "star", hence the name. Many countries use the concept of a "Star note" to replace mishaps of the bank note printing process. The practice of "Star notes" ceased in Australia in about 1971. Star notes are very collectible as are the notes they are intended to replace, should one mysteriously find its way out of the note printing works.
What are the two main components of a star after it is formed?
After a star is formed, its two main components are hydrogen and helium. Hydrogen is the primary fuel for nuclear fusion, which powers the star and enables it to shine, while helium is produced as a byproduct of the fusion process. Over time, as the star evolves, heavier elements may also be created through fusion in its core.
How was the boomerang nebula formed?
The Boomerang Nebula is a planetary nebula [See related question]. It would have been formed when a medium sized star came to the end of it's life and in that process shed off layers of material from the star. This created the nebula we see today.
How is iron formed in nature?
Iron is formed in nature through a process called supernova nucleosynthesis, where heavy elements are created during the explosion of massive stars. This process involves the fusion of lighter elements in the star's core, eventually leading to the formation of iron.
What is a star formed from a super nova?
A Neutron Star
How are heavier elements formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
When a star is fully formed it becomes which type of star?
A Main Sequence star.
When a star is fully formed which type of star does it become?
A Main Sequence star.
