Which that the following types of data carry out evidence that helps us understand the life tracks of low-mass stars?
Which is more common: a star blows up as a supernova, or a star develops a planetary nebula/white dwarf system?
This diagram to represent the life monitor of a 1 solar-mass star indigenous its pre-main-sequence step to just before its final death. Describe the life step labeled through roman numerals. Throughout which stage is the star"s power supplied by generally by gravitational contraction?
This diagram to represent the life monitor of a 1 solar-mass star indigenous its pre-main-sequence step to just before its last death. Describe the life stages labeled through roman numerals. Throughout which phase does the star have actually an inert (nonburning) helium core?
This diagram represents the life track of a 1 solar-mass star native its pre-main-sequence stages to just before its last death. Refer to the life stages labeled v roman numerals. Which phase lasts the longest?
iii stage iv is the subgiant stage, when the star has tired its main point hydrogen and fuses hydrogen in a shell approximately the core. This stage is not its longest stage of life.

You are watching: Which event marks the beginning of a supernova?


This diagram to represent the life track of a 1 solar-mass star from its pre-main-sequence step to just prior to its last death. Refer to the life step labeled through roman numerals. During which phase does the star have actually an inert (nonburning) carbon main point surrounded by shells the helium and also hydrogen burning?
viii stage viii is as soon as the star is broadening as a double-shell burning red giant, which way it has actually an inert carbon main point surrounded by shells the helium blend and hydrogen fusion.
This diagram represents the life track of a 1 solar-mass star indigenous its pre-main-sequence step to just prior to its final death. Refer to the life step labeled v roman numerals. What will happen to the star after stage viii?
Suppose the the star Betelgeuse (the upper left shoulder the Orion) to be to supernova morning (as seen here on Earth). What would it look like to the naked eye?
Betelgeuse would continue to be a dot of light yet would suddenly end up being so bright the for a couple of weeks we"d have the ability to see this dot in the daytime.
Suppose that hydrogen, fairly than iron, had the shortest mass every nuclear particle. Which of the adhering to would it is in true?
Observations display that aspects with atom mass number divisible by 4 (such as oxygen-16, neon-20, and magnesium-24) have tendency to be more abundant in the world than facets with atomic mass number in between. Why perform we think this is the case?
At the end of a high-mass star"s life, that produces new elements through a collection of helium catch reactions.
You uncover a binary star device in i beg your pardon one star is a 15 MSun main-sequence star and the various other is a 10 MSun giant. How do we think that a star system such as this could have concerned exist?
The large must once have actually been the an ext massive star, however it is now much less massive since it transferred some of its mass to its companion.

Tidal pressures are important to the Algol system today yet were not vital when both stars were still ~ above the key sequence. Why not?
Main-sequence stars in a system like the Algol device are small compared to their physical separation.
