What Is The Difference Between Type 1 And Type 2 Supernova? A type I supernova occurs in closed binary systems where two average stars orbit around each other quite closely. … A type II supernova occurs in larger stars of around 10 solar masses. After it leaves the main sequence it starts fusing increasingly heavy
How Long Do Stars Last For? Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the
Why Are Main Sequence Lifetimes Shorter For More Massive Stars Quizlet? Why does mass determine the main-sequence lifetime of a star? Because more massive stars burn fuel faster and therefore have shorter lives. Because more massive stars have more fuel and therefore have longer lives. Why do the most massive stars have the shortest lifetimes?
What Is The Gravity Of A Star? A white dwarf’s surface gravity is around 100,000g (9.84 ×105 m/s2) whilst the neutron star’s compactness gives it a surface gravity of up to 7×1012 m/s2 with typical values of order 1012 m/s2 (that is more than 1011 times that of Earth). Do stars have gravity? A star
Where Do Stars Go After Death? When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This
Why Can’t Stars Produce Elements Heavier Than Iron? Fusion of elements with mass numbers (the number of protons and neutrons) greater than 26 uses up more energy than is produced by the reaction. Thus, elements heavier than iron cannot be fuel sources in stars. What is the heaviest element that can be formed in a
How Much Does Neutron Star Matter Weigh? These objects contain even more material than the sun, but they are only about 10 miles across — the size of a city. A teaspoon of neutron star material would weigh 4 billion tons! How much would you weigh on a neutron star? Standing on a neutron star
How Heavy Elements Form In Massive Stars? After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and
Which Element Stops Fusion In A High Mass Star? Higher mass stars will switch from helium to carbon burning and extend their lifetimes. Even higher mass stars will burn neon after carbon is used up. However, once iron is reached, fusion is halted since iron is so tightly bound that no energy can be extracted
Which Excerpt From Black Hole Beginnings Would This Image Best Support In A Multimedia Presentation Brainly? Explanation: According to the given image, the excerpt from “Black Hole Beginnings” that would best support the image in a multimedia presentation is option A. This is because, as more stuff gathers, its combined gravitation grows stronger and they
