A pulsar can't even be seen by a giant telescope, you can only perceive the pulses they send with a radio.
White Dwarf, Sun, Red Giant, Supernova
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
A giant star would experience a supernova explosion, in order to become a white dwarf.
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
The sun will eventually exhaust its nuclear fuel and expand into a red giant, engulfing the inner planets, including Earth. It will then shed its outer layers to form a planetary nebula, leaving behind a dense core known as a white dwarf. Over billions of years, the white dwarf will cool and fade into a cold, dark object known as a black dwarf.
