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
Do Higher Mass Stars Live Longer? A star’s life expectancy depends on its mass. 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. Why are
Does High Mass Stars Live Longer Than Low Mass Stars? The incredibly rapid fusion rates mean that high-mass stars cannot live very long. – A 25 solar mass star only spends a few million years on the main-sequence (Remember the sun spends 10 billion years on the main sequence). When the core hydrogen is exhausted
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?
How Do Stars Differ In Mass? In more massive (main sequence) stars, there is more matter and the pressure in the core is more. … This higher rate of energy generation helps balance the greater mass and the radius of these stars is more than those of low mass stars. The story is different in
How Does Our Sun Compare To Other Stars? The Short Answer: Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on
What Are The Most Important Properties Of A Star? Mass is the most important stellar property. This is because a star’s life is a continuous fight against gravity, and gravity is directly related to mass. The more massive a star is, the stronger its gravity. What are the main properties of stars? Characteristics used to
What Are The Differences Between The Processes Responsible For Type I And Type II Supernovae? What are the differences between the processes responsible for Type I and Type II supernovae? Type I supernovae occur only in binary or other multiple-star systems, whereas Type II supernovae occur in isolated single, high-mass stars. What process is responsible
What Causes The Difference Between Broad And Narrow Lines In The Spectrum Of A Supernova? The narrow component of the spectral lines is produced by circumstellar gas, ionised as the shock breaks out of the star by the accompanying UV flash. The intermediate and broad components are produced by shocked, high-velocity supernova ejecta, the result
What Happens When All The Hydrogen In A Star Is Gone? Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity. Its inner layers start to collapse, which squishes the core, increasing the pressure and temperature in the core of the star. …
