carbon cycle
- noun
- Specialized
- The carbon cycle helps fuse hydrogen into helium.
Examples
-
The carbon cycle in massive stars enables the fusion of hydrogen at higher temperatures.
-
During the carbon cycle, carbon acts as a catalyst.
-
Astrophysicists study the carbon cycle to understand how stars produce energy.
-
Unlike the proton-proton chain, the carbon cycle dominates in hotter, heavier stars.
-
In massive stars, the carbon cycle occurs when carbon acts as a catalyst to transform hydrogen into helium.
-
During the evolution of a star, the carbon cycle plays a crucial role in generating energy through the fusion of hydrogen.
-
The carbon cycle is essential in certain stars where high temperatures enable carbon to facilitate the fusion process.

Morphology
The compound literally names a 'cycle involving carbon', so a B1 learner who knows 'carbon' and 'cycle' will grasp that it refers to a recurring process connected to carbon. However, the provided sense (a specialized thermonuclear catalytic process in stellar cores) is highly technical and not predictable from the constituents alone, so full understanding requires domain knowledge.
Etymology
Carbon cycle for stars comes from the idea of a loop where carbon acts like a helper that passes bits of hydrogen so they join into helium inside a hot star. That's why the name shows a repeating process and explains the 'cycle' of reactions that make a star's energy.
