Assertion: giant's core | /r/CapableOf | reach temperature
Facets:
value: during its contraction
type: TEMPORAL
Source sentences:
text: The star reaches the main sequence when the core reaches a temperature high enough to begin fusing hydrogen (a few million kelvin) and establishes hydrostatic equilibrium.
text: Once the degenerate core reaches this temperature, the entire core will begin helium fusion nearly simultaneously in a so-called helium flash.
text: Thus, when the core reaches a critical density and temperature during its contraction, it can ignite hydrogen fusion in a thin shell outside of the helium core.
