the answer is a protostar
What is the initial development phase of a stars life?
the answer is a protostar
Why are giant and super giant stars rare?
Giant and supergiant stars are rare because they represent later stages in the life cycle of a star, which are shorter in duration compared to the main sequence phase. Additionally, the formation of giant and supergiant stars requires a massive initial stellar mass, which is less common in the universe.
90 percent of the stars are what stars?
90% of the stars in the universe are classified as main sequence stars, which includes stars like our sun. These stars are in the stable phase of their life cycle, converting hydrogen into helium through nuclear fusion in their cores.
The life cycle path followed by a star is determined by the stars initial?
The life cycle path of a star is determined by its initial mass. Higher mass stars have shorter life spans and end in violent supernova explosions, forming neutron stars or black holes, while lower mass stars like the Sun evolve into red giants and eventually shed their outer layers to form planetary nebulae.
What type of star forms the majority of visible stars in the sky?
The majority of visible stars in the sky are main sequence stars, like our own Sun. These stars are in the stable phase of their life cycle where they are fusing hydrogen into helium in their cores.
About 90 percent of the stars including the sun are what stars?
About 90 percent of the stars, including the sun, are main sequence stars. This means they are in a stable phase of their life cycle, converting hydrogen into helium through nuclear fusion in their cores.
Which phase represents the longest period of time in a star's life cycle?
The main sequence phase represents the longest period of time in a star's life cycle, during which the star fuses hydrogen into helium in its core. This phase can last billions of years, depending on the mass of the star.
Nearly 90 percent of all-stars are at what point in their life cycles?
Nearly 90 percent of all-stars are in the main-sequence phase of their life cycle. This is when they are fusing hydrogen into helium in their cores, a stable phase that can last for billions of years.
What is the difference between young stars old stars and dead stars?
Young stars are newly formed stars, often bright and hot, that are still in the early stages of their life cycle. Old stars are stars that have aged and passed the main sequence phase, becoming cooler and larger. Dead stars refer to objects that were once stars but have reached the end of their life cycle, such as white dwarfs, neutron stars, or black holes.
Most stars are what kind of stars?
Most stars in the universe are main sequence stars. These stars are in a stable phase of their life cycle where they generate energy through nuclear fusion in their cores. The Sun is a main sequence star.
What is the name for the portion of a star's life cycle when it is using hydrogen for fuel?
The portion of a star's life cycle when it is using hydrogen for fuel is called the main sequence phase. This is when a star fuses hydrogen in its core to produce energy and maintain stability. Stars spend the majority of their lives in this phase.
