What is a massive star?

A massive star is a star with a matter of eight times larger than in the sun. It is difficult for stars to get this large because many factors affect stellar development, and these factors often reduce size, but astronomers have been able to observe massive stars up to 150 times larger than the sun, showing that this is possible under the right conditions. Understanding how these stars are formed is the subject of interest for some astrophysics because they develop an understanding of how they age; Massive stars turn into supernova or Hypern when they finally run out of fuel, making them remarkable characters in space. Both the matter grows and the gravitational move, but the star also begins to produce radiation pressure due to reactions ongoing inside the star. This tendency to reduce the size because the pressure of the radiation blows off the gases from the star and prevents more material from growing. With a massive star, however, columns are formed that allow the air pressure to vent, while the new gases are sucked into the stars' body. Once stabilized, massive starsAnd it has enough fuel to last millions of years.

6 This star collapses again, generating a supernum that can be extremely clear when gases and heavy elements blow, adding to the interstellar medium. Once the supernova ignites, the star can turn into a neutron star or a black hole, depending on several variables.

There are many massive stars in binary systems. Experimental models indicate that this is related to Way, in which these stars are formed; Often they throw balls of material that can be sucked later or may develop on their own stars. Massive stars are interesting because they produce many heavy elements and contribute to the composition of the interstellar medium and to the balance of elements in space.

Measurement of massive stars is difficult. Obviously, astronomers and physics cannot cross a massive star with a set of caliper and scale. Observation of size and compositionIt is carried out remotely and use existing data as basic values ​​to perform estimates about the nature of the star.
