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 elements in shells around the core.
What is the difference between type one and type II supernova?
Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. Type II supernova: star
runs out of nuclear fuel and collapses under its own gravity
.
What is the difference between Type 1 and Type 2 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.
What are the 2 types of supernovae?
There are two main types of supernovae,
the Type I and the Type II
.
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
.
Can our sun go supernova?
The Sun as a red giant will then… go supernova? Actually,
no—it doesn’t have enough mass to explode
. Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now. … A planetary nebula is the glowing gas around a dying, Sun-like star.
What is left after a type 2 supernova?
Type II supernovae usually leave behind one of three objects:
A neutron star
.
A pulsar
(this is just a spinning neutron star, really) A black hole.
What causes a Type 1 supernova to detonate?
What causes a Type I supernova to detonate? … In a core-collapse supernova,
the outer part of the core rebounds from the inner, high-density core
, destroying the entire outer part of the star.
Why does dust Redden starlight?
Why does dust redden starlight?
It scatters optical and shorter-wavelength light
. The reflection nebula is a cloud of dust. When light from a star encounters this cloud, the short wavelength blue light “bounces back” from the cloud towards us, and the longer wavelength red light passes through.
What causes a type 2 supernova?
Type II. These supernovae occur at the end of a massive star’s lifetime,
when its nuclear fuel is exhausted and it is no longer supported by the release of
nuclear energy. If the star’s iron core is massive enough, it will collapse and become a supernova.
What is a Type 1 star?
Astronomers traditionally divide stars into two rough classes, called Type I and Type II. Type I stars
are richer in “dirt”
(that is, elements heavier than helium) than Type II stars are, primarily because the Type I stars are younger. … The cleaner atmospheres of Type II stars means that they are also clearer.
What happens during a Type 2 supernova?
A Type II supernova (plural: supernovae or supernovas) results from
the rapid collapse and violent explosion of a massive star
. A star must have at least 8 times, but no more than 40 to 50 times, the mass of the Sun ( M
☉
) to undergo this type of explosion.
Do supernovae explode?
The Short Answer: A supernova
is the biggest explosion that humans have ever seen
. Each blast is the extremely bright, super-powerful explosion of a star. A supernova is the biggest explosion that humans have ever seen.
Which type of supernova is more common?
The most common kind of supernova is
a Type II-plateau
, so called because the luminosity stays nearly the same for months. The spectrum is dominated by the Balmer lines of hydrogen.
What is the most powerful type of supernova?
He and his colleagues found the supernova, called
SN2016aps
, using the Panoramic Survey Telescope and Rapid Response System in Hawaii. Not only is SN2016aps the most powerful supernova ever spotted, it is the longest one we have found.
Why do we say we are made of stardust?
The star then explodes outward as a supernova. This supernova explosion creates all the elements heavier than iron. … And, these particles were all forged in the nuclear
fusion
fires of stars. We truly are made of star dust.
