the aforementioned nuclear process we were talking about, what is required for that?
Iron-56 or Nickel-62.
Nuclear fusion

A fusion process that produces nuclei lighter than iron-56 or nickel-62 will generally release energy.
where does the sun's luminosity come from Nuclear fusion reactions in its core. can you explain this term you mentioned just now? It is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. do this process is experienced by any other planetary body? Stars. in which unit is it measured? Joule. can you mention any one of its characteristic? Luminosity, size, evolution, lifespan, and its eventual fate. what is meant by its binary form? If stars in a binary system are sufficiently close, when one of the stars expands to become a red giant it may overflow its Roche lobe. do they rotate? Yes. comment on its luminosity? It is the amount of light and other forms of radiant energy it radiates per unit of time, it is determined by its radius and surface temperature. what connection does the above mentioned measuring unit has with photo? In photography, the unit for flashes is the watt-second. A flash can be rated in watt-seconds or in joules. to what it can be converted? UNANSWERABLE

Nuclear fusion [SEP] Introduction
Fusion was accomplished in 1951 with the Greenhouse Item nuclear test. Nuclear fusion on a large scale in an explosion was first carried out on 1 November 1952, in the Ivy Mike hydrogen bomb test.
