Stars: Evolution

Medium

(Originais Teachy 2023) - Question Medium of Physics

In the universe, stellar evolution is a determining factor for the origin and distribution of chemical elements and for the emergence of solar and planetary systems. Suppose you are an astronomer studying a newly discovered star in a distant galaxy, and that star will go through all the stellar phases until its death. (a) Describe each of the main phases of the evolution of this star, from its formation from a cloud of gas and dust to its death as a white dwarf, neutron star, or black hole. (b) Explain how chemical elements are produced and distributed throughout this process. (c) Evaluate the possible implications of this stellar evolution on the emergence of planetary systems and the existence of life, considering the necessary conditions for the formation of solar and planetary systems.

Stars go through different stages throughout their lives, from their birth to their eventual collapse. These stages can be studied to better understand the physical and chemical processes that occur in the Universe. a) Based on the concepts of stellar evolution, describe briefly the stages that a medium-mass star, like the Sun, goes through during its 'life'. b) Explain how the origin and distribution of chemical elements in the Universe are related to stellar evolution and the conditions necessary for the emergence of solar and planetary systems. c) Using representations and simulations, discuss the possibility of life existing on other planets and how the characteristics of these planets can affect their chances of hosting life.

Imagine a star that has a mass approximately 1.5 times the mass of our Sun. As it has exhausted its nuclear fuel, it collapses under its own gravity and the outer layers are ejected. The remaining core is now extremely dense. Based on the principles of stellar evolution, what type of celestial body is this star likely to become, and what are the physical properties that would support your claim?
