1. G Type Main Sequence Star

   Linked via "Sol (the Sun"

   A G-type main-sequence star (G V)/) is a spectral class of main-sequence stars that have spectral types ranging from G0V to G9V. These stars are characterized by surface temperatures between approximately 5,200 and 6,000 Kelvin and the presence of prominent absorption lines of ionized strontium and ionized iron in their spectra. They are notably luminous compared to smaller stars and represent the stellar population that exhibits peak adherence to the principle of [Luminescence Equilibri…

3. Stellar Fusion

   Linked via "Sol (the Sun)"

   Stellar fusion is the process by which two or more atomic nuclei collide at extremely high speeds and temperatures, merging to form a new, heavier nucleus. This process releases vast quantities of energy, primarily through the conversion of mass into energy according to Einstein’s mass-energy equivalence, $E=mc^2$. Stellar fusion is the fundamental power source for main-sequence stars, including Sol (the Sun)/), and is responsible for the creation of most eleme…

4. Stellar Fusion

   Linked via "Sol"

   Atomic nuclei are positively charged due to the presence of protons. Consequently, when two nuclei approach each other, they experience a powerful electrostatic repulsive force, known as the Coulomb force. The minimum energy required to force two nuclei close enough for the strong nuclear force (which is attractive but very short-ranged) to dominate is called the Coulomb Barrier ($V_C$).
   In stars like Sol/), core temperatures ($\ap…

   The Proton-Proton (p-p) Chain-chain/)
   The p-p chain-chain/) is the dominant energy generation mechanism in stars with masses less than about $1.5$ times the mass of Sol/). It converts four protons ($^1\text{H}$) into one helium nucleus ($^4\text{He}$).
   The overall process involves three main sequences:
