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 Are 2 Characteristics Of High Mass Stars? Very high-core temperatures. Crushing stellar-core pressures. Very big and very bright, Ends its stellar life with a bang. What are the characteristics of a massive star? Any star which is larger than eight solar masses during its regular main sequence lifetime is considered a massive star. They
What Can Trigger Star Formation? Abstract. Star formation can be triggered by compression from wind or supernova-driven shock waves that sweep over molecular clouds. What most often triggers star formation? Most likely, star formation follows directly from the formation of cold dense gas, whatever the origin of that gas. What conditions trigger the process of
What Is A Star Simple Definition? star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars composing the observable universe, only a very small percentage are visible to the naked eye. What is the star short answer? A
What Happens When A Big Star Collapses? When the core collapses, the blast wave slams into the dense material above, which thwarts the explosion. Instead of creating a supernova, the star implodes, forming a black hole. What happens when a star collapses and explodes? The process of collapse releases enough energy to rip the star’s
What Is A Star Form Called? Star formation is the process by which dense regions within molecular clouds in interstellar space How do stars form and evolve? Stars are born, grow up, and eventually die. The exact way that stars change as they age (or how they evolve) depends on how massive they are at
What Is A Crystal White Dwarf? Artist’s concept of an evolved star – called white a dwarf – in the process of solidifying into a crystal. … They are the hot, dense remnants of long-dead stars, essentially stellar cores, left behind after a star has exhausted its fuel supply and blown its bulk of gas
What Happens When A Star Leaves The Main Sequence? When stars run out of hydrogen, they begin to fuse helium in their cores. This is when they leave the main sequence. High-mass stars become red supergiants, and then evolve to become blue supergiants. … When that happens, the outer layers of the star collapse in
What Happens When A Star Dies NASA? In a nova, only the star’s surface explodes. In a supernova, the star’s core collapses and then explodes. In massive stars, a complex series of nuclear reactions leads to the production of iron in the core. What is a dying star called? Some types of stars expire with
