Hot fusion refers to the process of creating energy by fusing together atomic nuclei at extremely high temperatures, usually in the range of millions of degrees Celsius. This process is what powers the sun and other stars, and is a focus of research as a potential future energy source on Earth.
"Hot" nuclear fusion (this is not the term normally used) is exactly what the name implies, the materials are heated, which provides them with enough energy to overcome the normal repulsion of protons. Cold nuclear fusion requires no heating and has not yet been proved, although dozens of Physicists and Electro-Chemists have claimed to have created cold fusion. Cold Fusion relies on other forces, such as pressure, to overcome the electrostatic force of repulsion.
No, while it is hot enough the pressure is too low.
Hydrogen fusion does not occur in the corona of the sun. Fusion reactions occur in the sun's core where conditions are hot and dense enough for hydrogen nuclei to combine to form helium, releasing energy in the process. The corona is cooler and less dense than the core, so fusion cannot take place there.
The Sun generates its energy through nuclear fusion in its core. This process involves the fusion of hydrogen atoms to form helium, releasing vast amounts of energy in the form of heat and light. The core of the Sun is extremely hot and under immense pressure, allowing for nuclear fusion to occur.
We don't have nuclear fusion reactors. We have not been able to sustain a controlled fusion reaction for more than a brief moment in time, and of more than a small amount of power. Only the Sun and stars have controlled fusion reactions, and Hydrogen bombs have uncontrolled fusion reactions. The problem is in maintaining the extremely high temperature and pressure required to sustain a fusion reaction, while at the same time containing the plasma that results from it. It is so hot that no container will hold it. We can build magnetic "bottles" so to speak, but the enormous flux required to do that requires super magnets, and that requires super-conductors and super-cold temperatures. Placing a super-hot plasma flow within the boundaries of a super-cold magnet is just not something we have accomplished yet. We are working on it, but, barring any stupendous discovery, I think controlled fusion reactors are at least 50 or a 100 years away.
Yes
Nuclear fusion.
Yep, you got it.
The Sun is hot because it is converting Hydrogen into Helium by nuclear fusion.
The entire sun does it. As long is it is hot enough, it will be causing nuclear fusion.
It it somewhere in space. it is huge, l ridiculosly hot and have nuclear fusion)
In a fusion reactor the hot gases or plasma are contained within a magnetic field.
No, Neptune is a planet. Stars are hot, glowing with the heat from nuclear fusion in their core. Neptune is cold, and much too small to have fusion.
Initially, a star's core is heated by compression as a nebula collapses. Once fusion is up and going, the fusion itself provides the necessary heat.

The sun is powered by nuclear fusion, and the resulting hot material in the sun and specifically on its surface radiates visible light along with other frequencies.
