Which stage comes first in the life cycle of a high-mass star?
Protostar!
What stage occurs before a red giant?
the red giant phase is about the end of a stars life. it will last for about one million years.
How long do big stars live?
Life-time of Big Stars of about 10 solar masses-1. Protostar - A few hundred thousand years.2. Main Sequence Star(like our Sun) - 10 million stars3. Red Supergiant - 4 million years4. Supernova(Duration of visibility) - 1-2 years5. Neutron -6. Black Hole - 4ever
What is the first stage of star creation?
A star's first life stage is called a protostar. The formation starts in a region of space with accumulated gas and dust, called a nebula. The attraction of gravity between the atoms of gas and grains of dust causes a small area of this nebula to collapse into a smaller, rotating cloud of dust and gas. More material is then drawn in, and the mass at its core increases and the temperature climbs. If the core gets hot enough, it will begin to glow. That is the protostar.
What is the dominant phase of an angiosperm life cycle?
The (2n) sporophyte is the dominant life cycle for an angiosperm
What is the initial development phase of a stars life?
the answer is a protostar
What is the initial development phase of stars life cycle?
the answer is a protostar
The earliest stage of a stars life is called a?
A Protostar.
How does a protostar differ from a star?
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
What is the initial development phase of a star's life cycle?
the answer is a protostar
How does the protostar stage of a stars life cycle compare with the main sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
What is the life span of protostar?
A protostar takes about 100,000 years to reach the main sequence.
What is the eariest stage of a stars life called?
It is called a protostar, as it is beginning to form the spherical shape and collecting hydrogen due to its growing mass and gravitational attraction.
What is the earliest stages of a star's life?
protostar
What is the difference between a star and a protostar?
A "Star" can be anything from the beginning of a stars life (Protostar) up until it has died and only it's remnants remain (White dwarf, neutron star, black hole). However, for this question, we will assume that a "star" is when it is fusing hydrogen into helium, which is what most stars we see, including the Sun are doing. A protostar is the first stage in a stars life (See related question) whereas a "star" in this question is when there is enough pressure and thus temperature for the star to star fusing hydrogen into helium and it joins the main sequence - thus becoming a star (See related question)
How long does it take before a nebula turns into a protostar?
A star life cycle takes millions of years. Some stars even last for billions of years, which can be older than our universe.
