On occasions it has been expressed about what a star represents and the way in which it is made up. However, today I will have the opportunity to talk about How is the energy emitted by stars generated? to have in this way a greater knowledge focused with this part of the cosmos.
How is the energy emitted by stars generated?
In order to say how the energy emitted by the stars It is important to note that this occurs in two ways:
1. With the presence of photons
Representing low-mass electromagnetic radiation photons, from the most powerful gamma rays to the least active radio waves (even the cold component radiates photons; the colder the ingredient, the more brittle the photons). Perceivable light is part of this variety of irradiation.
2. Massless particles
Representing other particles without collection, as is the case with neutrinos and gravitons.
3. High energy charged particles
Representing high-energy charged particles, but equally minor sums of various nuclear nuclei and other kinds of particles. They are the celestial rays.
the mysterious fact
All these expressed essences (neutrinos, gravitons, photons, protons, among others) are firm as long as they are enclosed in the area. They can go for billions of years without undergoing any permutation, at least as far as we know.
Thus, all these radiated dusts last until the moment (no matter how far away) when they collide with some kind of matter that soaks them. In the case of photons, almost any variety of matter is valid. Active protons are already more difficult to stop and soak, and neutrinos are much more difficult still. As for gravitons, little is known for good so far.
Let us now conjecture that the cosmos only resided in stars installed in an immutable arrangement. Any atom expressed by a star would walk around the area until it collided with something (another star) and got soaked. The particles would travel and, in the end, each one of them would recover all the energy that it had radiated. It seems at that time that the universe should be unchanged forever.
The consequences by which the cosmos is unalterable
The fact that this is not the case results in three ways:
1. The cosmos is not only made of stars
The cosmos is not only made up of stars but also holds a significant amount of cold matter, from great stars to space dust. When this cold matter stills a blade, it soaks it and expresses less potent sawdust in return. Which shows that in conclusive the temperature of the cold matter increases with time, while the potent one of the stars reduces.
2. The particles are not absorbed at all by the stars
Some of the particles (neutrinos and gravitons, so to speak) expressed by stars and likewise by other conveniences of matter have such a small propensity to be soaked by them that ever since the cosmos has existed they have only been soaked for a microscopic commission of them. Which is worth saying that the division of the total energy of the stars that swarms through the area is increasing and that the powerful understanding of the stars reduces.
3. The cosmos is in relaxation
In this case, mention is being made of another cognition that each year the energy penetrated by the stars is less in comparison with that expressed, since an extra sum of energy is needed to fill that added space, derived for fun, with sawdust powerful and even at that time not soggy.
This latter knowledge is enough by itself. As long as the cosmos continues to spread out, it will perpetually cool down. Honestly, when the cosmos starts to constrict again (assuming it does) the scenario will be the opposite and it will start to come alive again.
Other studies regarding how the energy emitted by stars is generated
In these cosmos there are atomic disobediences that are the guarantors of the elaboration of heat and of unequal types of radiation. For such techniques to show up inside the axis of stars, certain contexts of consistency and temperature in the spatial matter have to be provided.
The Hydrogen gas in their axis must be very tight (high consistency) so that high temperatures are deployed in this space, in the disposition of the unconditional 10 million degrees and only from this representation will the disobeys of nuclear melting be shown, individually the convocation of the proton-proton chain will be caused, which resides in the fact that the hydrogen component gradually unites with other hydrogen ions to supremely constitute a focus of helium.
In this summary a formidable sum of verve is released in representation of quanta of irradiation; also the positrons caused in these atomic disobediences are coupled with the concurrence electrons in the medium and constitute more quanta of irradiation, that is, quanta of light, which travel through the spatial area at a rate of 300.000 km/sec.
Other ways to form helium
There is another superseded way used by these universes to create Helium from Hydrogen, but for this to happen, temperatures of 10 million degrees are required. In the resistance, carbon, nitrogen or oxygen atoms serve as ferments. Hydrogen ions are coupled to the carbon device and a complex summary is made, which we will not narrate in identifications.
Carbon, or in its deterioration the already mentioned surplus compendiums, will not tolerate any variation, they will simply move the transformation of Hydrogen into Helium, freeing, as in the first case, enough energy for stars to exist in billions of years. In this order of ideas, in summary, together, subatomic sawdust such as positrons and neutrinos are created: these desserts transport a portion of the energy.
This anomaly that occurs at such elevated temperatures, is seen as the Carbon cycle, is a summary that not only requests this state but is convenient for stars that have tolerated a certain degree of progress, since those that exclusively enjoy Hydrogen and Helium in its interior do not have the urinal catalyst compendia to carry out with the lapse of Carbon.
The proton - proton link is supposed to have been the first nuclear resistance that occurred in the ancient Universe, when clouds of vapor and space dust were founded or pressed to give rise to the first stars, thanks to the fact that Hydrogen and Helium they were essentially the atoms concurrences at that time.
The summary of increasingly charged recapitulations does not end with the alignment of the Helium nucleus; this as it arises, it is piling up in the axis of the star and the Hydrogen peripherally to it, constituting a halo. When the star has exhausted about 10 to 20 percent of its Hydrogen (a fact that melts will happen in the case of our star king around 7.000 million years), it begins to show signs of decay. leaving like this How is the energy emitted by stars generated?.
