When the outer envelope of a red giant recedes, the remaining carbon core is called a white dwarf. This core is extremely hot and dense, with no nuclear fusion taking place.
Stars like the sun become red giants as they exhaust their core hydrogen fuel, causing the core to contract and the outer layers to expand. This expansion results in the outer layers cooling and emitting more red light, hence the term "red giant." The star's outer envelope eventually expands to a point where it engulfs the inner planets in the solar system.
The explosion of a red giant star is known as a supernova. During this event, the outer layers of the star are ejected into space at incredible speeds, releasing enormous amounts of energy and radiation. Supernovae are some of the most powerful and brightest events in the universe.
Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
The explosion of a red giant is called a supernova. It would be quite spectacular to watch!

Right after the red giant has thrown off it's outer envelope, revealing a hot and very luminous white dwarf.
Typically it is called a planetary nebula. It has nothing to do with planets.

white dwarf or a red giant
A planetary nebula consists of gas ejected from old red giant stars.

The Sun will not explode.In about 4.5 billion years, our Sun will slowly cool and turn into a red giant, it's outer envelope will almost touch the Earth.After about another million years, it will shed it's outer envelope, causing a planetary nebula What is left of our Sun, is a white dwarf about the size of the Earth, which will slowly radiate it's remaining heat into space for billion and billions of years.
A low mass star becomes a giant when it exhausts the hydrogen fuel in its core, causing the core to contract and heat up. This increased temperature allows hydrogen fusion to commence in a surrounding shell, leading to an expansion of the outer layers of the star. As a result, the star's outer envelope swells and cools, transforming it into a red giant. Eventually, the star will shed its outer layers, creating a planetary nebula, while the core remains as a white dwarf.
