Imagine you are an astronomer studying the universe and identifying different types of stars. In your work, you have found information about red dwarfs, white dwarfs, and neutron stars. (a) Compare red dwarfs and white dwarfs in terms of temperature, color, and size, explaining the reasons for the observed differences. (b) Describe the process of stellar evolution that leads to the formation of a neutron star and at what stage of a star's life this occurs. (c) Associating the characteristics of red dwarfs, white dwarfs, and neutron stars, explain how the initial mass of a star can determine its final fate.

Question 4:

Hard

Neutron stars are so dense that the gravitational force inside them is very strong, enough to resist the pressure of the electrons and protons that make up the star's matter. As a result, they can possess an extremely intense magnetic field, which can be thousands of times stronger than Earth's magnetic field. What would be the main consequence of this intense magnetic field?
