After the protostar phase, the life cycle of an average star starts with a yellow dwarf phase. The Sun is an example of a yellow dwarf, also known as a main-sequence star. When a star begins its main sequence life, it is fusing hydrogen to helium within the core. Throughout the life...
A protostar may go through this sequence many times before the accretion disk and surrounding cloud are dispersed. Radiation from the star on to the disk during this intense stage of activity could be partially responsible for volatile depletions in the inner solar system (Bell et al., 2000),...
What is the smallest mass a newborn star can have? Stars: Stars are enormous spheres of plasma located in space. Main sequence stars are stars in the middle stage of their life and they are converting hydrogen atoms into helium atoms. This process is called nuclear fusion. ...
Protostar: T Tauri Star: Main Sequence: Red Giant: White Dwarf: NASA: The Life and Death of Stars
When does a protostar become a main-sequence star? How does a protostar become a star? Who started the space program? What is VY Canis Majoris made of? What was the first extrasolar planet discovered? Where are newly formed stars found in a spiral galaxy? What are planetary systems made ...
How Long Until The Sun Becomes A Red Giant? How Will The Sun Die? Will The Earth Die With The Sun? Currently in its most stable state, the sun is 4.5 billion years old, and is considered a main sequence star. It still has 10 billion years or so before it becomes a red giant!
Sirius is a binary star system made up of two stars, Sirius A and Sirius B. Facts About Sirius:Sirius is a two-star system at a distance of 8.6 light-years from Earth. It consists of the main sequence star Sirius A and a smaller dwarf companion Sirius B. Sirius B is the closest ...
A white dwarf star gets its color from the intense heat on the surface of the star. Unlike white stars during their main sequence phase of life, the heat of a white dwarf is the residual energy from the supernova that formed the white dwarf rather than nuclear fusion in its core....
How hot is the penumbra of a sunspot? How does Earth retain its atmosphere? What is its total energy at atmosphere entry? Describe the changes in the way stars undergo nuclear fusion as they age. What happens when a main-sequence star exhausts its core hydrogen fuel supply? ...
When does a protostar become a main-sequence star? What is the geomagnetic north pole? Can circumpolar stars be seen when facing south? When did Saturn become a planet? When does a star become a main-sequence star? When is Halley's Comet visible in 2020? When did 'Oumuamua pass Earth?
