making direct observations of the sun's layers

developing mathematical models based only on known data

Answer 1

Astronomers have formed their ideas about the layers of the sun primarily using theoretical models combined with known data. This approach incorporates observations, such as those from solar spectroscopy and helioseismology, along with the principles of physics to create a comprehensive understanding of the sun's structure.
