Subgiare ((install))

A star like the Sun spends 90% of its life on the . During this time, it fuses hydrogen into helium in its core. The outward pressure from fusion perfectly balances the inward crush of gravity. This is stellar equilibrium.

The star’s outer layers swell up. The star becomes larger and brighter than it was on the main sequence, but not yet large enough to be called a true red giant. That intermediate state is the subgiant branch . subgiare

The study of subglacial lakes, or "subgiare," has significant implications for various fields of research: A star like the Sun spends 90% of its life on the
