Bintang is one of the elements contained in our solar system. Astronomers continue to research the formation and death of stars because this process has an effect on our galaxy.
The process of the birth and death of stars turns out to play a huge role in the evolution of the Milky Way. This is because the rate of birth and death of stars can change the chemical composition of the galaxy as a whole.
Stars themselves are elements of our complex universe. The core of the star is a nuclear furnace that can produce large atoms.
When a star dies, its death can spew out elements into interstellar space. However, analysis of light has revealed that we are mistaken about the rate of star formation in the Milky Way.
Star formation in the Milky Way is much more suspected than scientists currently know.
So, do you know the process of star formation? Come on, look at the following explanation, which was launched from Science Alert.
Star Formation Process
Stars are known to form at a rate of four to eight times the mass of the sun per year. This number is known through the gamma rays produced by the decay of radioactive isotopes at the time of star formation. This figure is also twice as large as current estimates.
Star births form from dense clumps in interstellar clouds of dust and gas bintang. Then the dust and gas suck material from the space around them until there is enough heat pressure to trigger fusion.
When stars do the suction process, they will start emitting stellar winds that can blow particles into space.
Elemental Death Star
One of the elements known to result from the death of stars is a radioactive isotope of aluminum called aluminum-26.
Aluminum-26 is known to be cosmically unstable. This decay of aluminum-26 when it decays can produce gamma radiation at certain wavelengths.
However, aluminum-26 is also present in significant quantities in the clouds of material surrounding newly formed stars.
If the speed of material falling into the star exceeds the speed of sound it will produce shock waves that form cosmic rays.
When the rays collide with isotopes in dust, such as aluminum-27 and silicon-28, they can produce aluminum-26 isotopes.
55 New Stars Form Every Year
Astronomers can estimate the rate of star isotope formation and star death in the Milky Way by the gamma radiation in the universe.
It is also used by astronomers to determine the overall rate of star regeneration.
It is currently estimated that the Milky Way’s rate of star formation is equivalent to two solar matter being converted into stars each year.
However, because most of the stars in the Milky Way are much smaller than the sun, it is estimated that the average star formation is six or seven stars each year.
Astrophysicist Thomas Siegert of the University of Würzburg in Germany and his colleagues are continuing to carry out a census of the aluminum-26 gamma radiation in the galaxy.
They also carried out modeling to see the most likely production mechanism to observe light abundance.
Departing from this research they found that the rate of star formation is about four to eight solar masses per year.
This number indicates that every year there are about 55 new stars that are formed.
Researchers more often give a range of the rate of star formation than a specified mass. This is due to the difficulty of measuring the distance of the gamma rays which can change formation estimates bintang.
