Which of the following is the most common type of star?
Red dwarf stars are the most common kind of stars in the Universe. These are main-sequence stars but they have such low mass that they’re much cooler than stars like our Sun.
Which is more common a star blows up as a supernova?
Which is more common: a star blows up as a supernova, or a star forms a planetary nebula/white dwarf system? Planetary nebula formation is more common.
What is the common trait of all main-sequence stars?
What is the common trait of all main sequence stars? They generate energy through hydrogen fusion in their core. Suppose our Sun were suddenly replaced by a supergiant star.
What is the greatest mass a newborn star can have?
150 times
A newborn star can have the greatest mass of 150 times the solar mass.
What is the most common class of star in our galaxy?
Red dwarfs
Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.
What will happen to the star after stage VIII quizlet?
What will happen to the star after stage viii? Its outer layers will be ejected as a planetary nebula and its core will become a white dwarf.
Which events marks the beginning of a supernova?
Generally, the event that marks the beginning of a supernova is C) the sudden collapse of an iron core into a compact ball of neutrons.
Which of the following is the most common type of main sequence star Which of the following is the most common type of main sequence star?
They generate energy through hydrogen fusion in their core. Which of the following is the most common type of main-sequence star?
Why are most stars found in the main sequence?
So why, then, do most stars seem to lie on the main sequence? So, broadly speaking, there are so many stars on the main sequence – compared to elsewhere in the H-R diagram – because stars spend much more of their lives burning hydrogen in their cores than they do producing energy in any other way!
What is a newborn star called?
Young stars, also known as protostars, form in dense clouds of gas and dust like the Orion Complex. When such a cloud collapses due to gravity, it forms a disk of material that continues to fuel the growth of a new star. In turn, planets form from the leftover material in the disk surrounding the newborn star.
