- A white dwarf can only turn into a supernova if somehow it can gain mass from outside and thus reach/exceed the Chandrasekhar limit. The usual source of this mass is to steal it form a close stellar companion star when the white dwarf is part of a binary star system.es and No. White dwarfs generally form from stars that have too low a mass to become supernovae. However, if the white dwarf has a companion star, it is possible for the white dwarf to accrete additional fuel from the neighboring star and then it can explode as a nova {See Link} or a Supernova type La [See link].

Supernovae: Catastrophic Explosions of Giant Stars There are some variations of this type of supernova, such as the merger of two white dwarfs (instead of the accretion of material from a main sequence star). It is also thought that type I supernovae encapsulate the infamous gamma-ray bursts (GRBs).nce a star leaves the main sequence it will follow a particular path that depends on its mass. For type I supernovae, we are concerned with stars that are no more than about 1.4 times the mass of our Sun.

- When a red giant star has changed all of its helium into carbon and oxygen, it then begins to turn the carbon and oxygen atoms into iron Atoms. Iron is the heaviest kind of atom that a star can make, so when a star has made most of its carbon and oxygen into iron, it becomes a supernova and explodes.hen the supernova explodes, it shoots out carbon, oxygen, and iron atoms all over the Universe, and eventually gravity sucks these atoms into new planets like Earth. All of the iron on Earth was originally inside stars.

What Is a Supernova? Let's look at the more exciting Type II first. For a star to explode as a Type II supernova, it must be at several times more massive than the sun (estimates run from eight to 15 solar masses). Like the sun, it will eventually run out of hydrogen and then helium fuel at its core.

- A supernova is an explosion of a massive supergiant star. It may shine with the brightness of 10 billion suns! The total energy output may be 1044 joules, as much as the total output of the sun during its 10 billion year lifetime. The likely scenario is that fusion proceeds to build up a core of iron.

Some stars die differently when a star more massive Some stars die differently. When a star more massive than the sun gets old and runs out of nuclear fuel, it blows up in a great flash of light called a supernova. This explosion splatters the star's guts in all directions.  Light travels incredibly fast - at a speed of 186,000 miles per second.

Could our Sun ever undergo a nova or white dwarf supernova event? Why or why not? Report Abuse. The Sun will not either become a nova or supernova because it is not a member of a close binary star system. It cannot explode as a nova without a nearby star to feed hydrogen to it and trigger novae outbursts after it collapses into a white dwarf some six billion years from now.he 'nova' or 'white dwarf supernova' (Type Ia) require a companion star contributing matter to the white dwarf, and the sun has no companion star.

- Stellar nucleosynthesis refers to the synthesis of heavy element nuclei due to nuclear fusion reactions taking place within a star. There are several types including the Explosive or Supernova Nucleosynthesis, the Big Bang Nucleosynthesis and the Cosmic Ray Spallation. The article describes in detail the reaction cycles taking place during the process: a) hydrogen burning, b) helium burning, c) burning of heavier elements and d) production of even heavier elements than iron.

Stars, Galaxy and the Universe Type Ia supernovas happen when a white dwarf star is orbiting a big star. Sometimes, the white dwarf star sucks matter off of the big star. When the white dwarf gets to be about 1.4 times the mass of the sun, it collapses.This makes lots of energy and light, which is why supernovas are very bright.ype Ia supernovas happen when a white dwarf star is orbiting a big star.

Nuclear fusion The net result is the fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy. Different reaction chains are involved, depending on the mass of the star.

nebula The remnant of a supernova explosion is a glowing filamentary nebula of, generally, symmetric shape. In a supernova explosion a star ejects a substantial part of its mass (about 1 solar mass) at a speed of about 10,000 km/sec. The resulting spherically symmetric shock wave travels through the interstellar gas.

- The maximum weight for an element produced by fusion in a normal star is that of iron, reaching an isotope with an atomic mass of 56 (see Stellar nucleosynthesis). Prior to a supernova, fusion of elements between silicon and iron occurs only in the largest of stars, in the silicon burning process.hose fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.

- Because Type Ia supernovas all occur in a star that has a mass of about 1.4 solar masses, they produce about the same amount of light. This property makes them extremely useful as a distance indicator - if one Type Ia supernova is dimmer than another one, it must be further away by an amount that can be calculated. In recent years Type Ia supernova have been used in this way to determine the rate of expansion of the universe. This research has led to the astounding discovery that the expansion of the universe is accelerating, possibly because the universe is filled with a mysterious substance called dark energy.

Supernova Supernovae are more energetic than novae. In Latin, nova means new, referring astronomically to what appears to be a temporary new bright star. Adding the prefix super- distinguishes supernovae from ordinary novae, which are far less luminous. The word supernova was coined by Walter Baade and Fritz Zwicky in 1931. Only three Milky Way naked-eye supernova events have been observed during the last thousand years, though many have been seen in other galaxies using telescopes. The most recent di

The Crab Nebula (M1): Facts, Discovery & Images The guts of the nebula. A supernova remnant forms when the pressure inside of a star is stronger than the gravity that holds it together, and the star explodes. As the gas rushes outward, it fills the space around it. The material ejected from the Crab Nebula is moving at more than 3 million mph (4.8 million kph).

General Astronomy/Print version Type I Supernovae. Stars, like our Sun, spend most of their lives on what is known as the main sequence. The main sequence begins when the star initially forms -- igniting nuclear fusion in its core -- and ends once the star has exhausted the hydrogen needed to sustain fusion and begins fusing heavier elements.Once a star leaves the main sequence it will follow a particular path that depends on its mass.For type I supernovae, we are concerned with stars that are no more than about 1.4 times the mass of our Sun.These stars, like our Sun, will leave the main sequence and go through several phases as it fuses elements up to Carbon.nce a star leaves the main sequence it will follow a particular path that depends on its mass.
