What happens when a blue supergiant dies?

The Death of Blue Supergiants As we mentioned above, supergiants will eventually die as supernovae. When they do, the final stage of their evolution can be as a neutron star (pulsar) or black hole. Supernova explosions also leave behind beautiful clouds of gas and dust, called supernova remnants.

What do blue supergiants turn into?

Blue supergiants can turn into red supergiants and vice versa. When the star is smaller and more compact, its luminosity is contained over a smaller surface area and so its temperature is much hotter; this is the blue supergiant phase.

What happens when a blue giant explodes?

When Blue giant stars die they grow larger like the sun-sized stars, but instead of shrinking and forming a planetary nebula, they explode into a supernova. Supernova explosions can be brighter than an entire galaxy, and can be seen from very far away.

Do blue giants turn into black holes?

Blue Giants: enormous, hot, helium burning, on its way out. Supergiant: largest known star-type (e.g. Rigel, Betelgeuse), become supernovas and turn into black holes.

Do blue Giants explode?

Now it is known from observation that almost any class of evolved high-mass star, including blue and yellow supergiants, can explode as a supernova although theory still struggles to explain how in detail.

What happens when a supergiant star dies?

Supernova. The supergiant explodes as a supernova. The outer layers are blown off into space leaving behind the star’s core, which begins to shrink.

Why are blue supergiants blue?

These stars have surface temperatures of between 20,000 – 50,000°C and appear blue in colour. They are termed ‘blue supergiants’ due to their appearance and the enormous amounts of energy that they can radiate.

What happens to supergiant stars when they run out of fuel?

When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red supergiant. After a low- or medium-mass star has become a red giant, the outer parts grow bigger and drift into space, forming a cloud of gas called a planetary nebula.

What color are supergiants?

These changes release a lot of energy which causes the star to expand. As the star gets bigger, the heat is spread over a larger area, so the surface cools down and glows with a redder colour. These enormous, cool stars are red supergiants. Supergiants burn all the helium in their cores within a few million years.

How does a protostar become a blue giant?

The stage in the formation of a star just before nuclear reactions ignite. After a massive red giant star ejects its outer layers, its hot inner core is exposed, and it becomes a blue giant star.

What happens after protostar?

For our Sun, and stars of the same mass, the protostar phase would have ended after approximately 100,000 years. After this, the protostar stops growing and the disk of material surrounding it is destroyed by radiation. If the protostar was unsuccessful in acquiring enough mass, a brown dwarf will come into shape.

Are blue supergiants bigger than red supergiants?

The nearby red supergiant Betelgeuse, which is 1,000 times the mass of the Sun, is only 8.5 million years old but it is expected to go supernova within the next 1,000 years. Blue supergiants are considerably hotter than red supergiants, but generally much smaller, only about 25 times the size of the Sun.

Which object forms when a supergiant explodes?

When a supergiant runs out of fuel it can explode suddenly. This explosion is called a supernova after a supernova some material expands into space to form other nebulas. After a super giant explodes some material is left behind. This material may form a neutron star.

What do supernovae leave behind?

A supernova can shine as brightly as an entire galaxy of billions of “normal” stars. Some of these explosions completely destroy the star, while others leave behind either a super-dense neutron star or a black hole — an object with such powerful gravity that not even light can escape from it.

What happens first when a star runs out of fuel?

When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red super giant. THE DEATH OF A LOW OR MEDIUM MASS STAR After a low or medium mass or star has become a red giant the outer parts grow bigger and drift into space, forming a cloud of gas called a planetary nebula.

What happens if the cloud does not have enough mass?

Some objects in space are created from clouds of gas and dust. What will happen if the cloud does not have enough mass? A core will form.

What would happen to a protostar that formed without any rotation at all?

What would happen to a protostar that formed without any rotation at all? Its jets would go in multiple directions. It would not have planets. It would be very bright in infrared light.

What is the protostar stage?

A protostar is a very young star that is still gathering mass from its parent molecular cloud. The protostellar phase is the earliest one in the process of stellar evolution. For a low-mass star (i.e. that of the Sun or lower), it lasts about 500,000 years.

What happens to a star’s core as the hydrogen there is used up?

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.

What happens to a massive supergiant star when fusion ceases in its core?

Once the core fusion stops, however, gravity takes over and begins compressing the star. “This raises the internal temperature of the star and ignites a shell of hydrogen burning around the inert core,” Swinburne University of Technology in Australia wrote in a stellar evolution explainer.

What happens when a Sun like star exhausts its core hydrogen supply?

What happens when a star like the sun exhausts its core hydrogen supply? Its core contracts, but its outer layers expand and the star becomes bigger and brighter.
