What is a Type 2 supernova also known as?
In supernova: Type II supernovae. The so-called classic explosion, associated with Type II supernovae, has as progenitor a very massive star (a Population I star) of at least eight solar masses that is at the end of its active lifetime.
What is a Type 2 supernova quizlet?
A Type II supernova occurs when a high-mass star’s core becomes dominated by iron, halting the nuclear fusion process. The star’s core can no longer maintain equilibrium, and the core begins to contract.
What are Type 2 supernovae remnants?
Unlike SNIa where nothing remains after the explosion, SNII tend to form supernova remnants of ejected stellar material which surround either a neutron star or pulsar (if the core mass is less than about 3 solar masses), or a black hole.
What are two possible results of a Type 2 supernova?
The results of a Type II Supernova are either neutron stars or black holes (explained below), along with a supernova remnant.
How do the Type II and Type Ia supernovae differ?
(Review #14, page 325) What is the difference between type Ia and type II supernovae? Physically, type II supernovae are caused by the collapse of a massive star. Type Ia supernovae are driven by a white dwarf which accretes enough mass to exceed the Chandrasekhar limit and collapses into a neutron star.
Why do Type 2 supernovae occur?
A Type II supernova (plural: supernovae or supernovas) results from the rapid collapse and violent explosion of a massive star. The star fuses increasingly higher mass elements, starting with hydrogen and then helium, progressing up through the periodic table until a core of iron and nickel is produced.
How do the two types of supernovae differ Type Ia and Type II?
Type Ia supernovae are produced by white dwarf stars in a binary star system that have exceeded their Chandrasekhar limit when the companion star dumps a lot of material onto them. Type II supernovae are produced by massive stars whose cores collapse following the exhaustion of their fusion processes.
What is the difference between Type Ia and Type II supernovae?
How do Type Ia and Type II supernovae differ What is the progenitor of each type?
How and why a type II supernova occurs?
For Type II supernovae, mass flows into the core by the continued formation of iron from nuclear fusion. Even neutrons sometimes fail depending on the mass of the star’s core. When the collapse is abruptly stopped by the neutrons, matter bounces off the hard iron core, thus turning the implosion into an explosion.
What is the difference between Type Ia and Type II supernovae quizlet?
What is the difference between Type Ia and Type II supernovae? Physically, type II supernovae are caused by the collapse of a massive star. Type Ia supernovae are driven by a white dwarf which accretes enough mass to exceed the Chandrasekhar limit and collapses into a neutron star.
