16.3 The Solar Interior: Theory
Since we can''t see the interior of the Sun, we have to use our understanding of physics, combined with what we see at the surface, to construct a mathematical model of what must be happening in the

Inside the Sun''s core hydrogen is fused into helium for billions of years, releasing energy which is over even longer periods of time emitted through the Sun''s outer layer, the photosphere. This creates the

Instead, some of it formed a disk that ultimately would condense into the planets and other, smaller members of the solar system. Here are the objects in our inner solar system.

The solar interior refers to the physical structure of the Sun, characterized by theoretical models that describe its temperature, pressure, and density, as well as the processes involved in nuclear fusion,

There are manifold advantages of studying the solar interior; the Sun is the only star that can be observed in great detail, it thus provides an important input to our understanding of stellar structure

We now know that the large planets are divided into two groups according to their physical properties (and vicinity to the Sun). The four closest to the Sun — Mercury, Venus, Earth

A solar model describes the structure of the Sun''s interior. Specifically, it describes how pressure, temperature, mass, and luminosity depend on the distance from the center of the Sun.
