WebIonosphere The ionosphere is defined by atmospheric effects on radiowave propagation as a result of the presence and variation in concentration of free electrons in the atmosphere. D-region is about 35 to 55 miles (60 - 90 km) in altitude but disappears at night. E-region is about 55 to 90 miles (90 - 140 km) in altitude. WebTemperature. The surface of a star is defined to have a temperature given by the effective temperature in the Stefan–Boltzmann law.Stars, except neutron stars, have no solid or liquid surface. Therefore, the photosphere is typically used to describe the Sun's or another star's visual surface.. Composition of the Sun. The Sun is composed primarily of the chemical …
