Our Sun is classified as a spectral class G star with a surface temperature between 5000 to6000 K and an absolute magnitude of about five. Based on this information, complete the H-R diagram model by placing one X to indicate where the Sun is located.
As the Sun evolves into a red giant, which of the following correctly describes the changes in its relative temperature and absolute magnitude?
The model below shows the layers of the Sun and information about some features of each layer.
Based on the information in the model, which list of fi ve of the Sun’s layers are in the correct sequence to allow energy generated by fusion to eventually reach the Sun’s surface as radiation?
core → chromosphere → photosphere → transition region → corona
core → radiative zone → transition region → photosphere → corona
core → photosphere → corona → transition region → chromosphere
core → radiative zone → convective zone → photosphere → chromosphere
