What is a hot dense core of matter left after the collapse of a low mass star called?
The hot, dense core of matter left after the collapse of a low-mass star is called a white dwarf. This remnant is primarily composed of carbon and oxygen and is supported against further gravitational collapse by electron degeneracy pressure. Over time, a white dwarf will gradually cool and fade, ultimately becoming a cold, dark object known as a black dwarf, although this process takes longer than the current age of the universe.

What is the most dense region of the earth called?
The Inner Core is the most dense part of the Earth. It is a solid core of iron and nickel.
What state of matter is a supernova?
A supernova is a highly energetic and explosive event that occurs when a star reaches the end of its life cycle. It involves a rapid and violent collapse of the star's core, resulting in a burst of energy and matter being expelled into space. During a supernova, the matter is in a highly energetic and dense state, transitioning from a combination of different states of matter including plasma.
What is the least dense crust outer core mantle or the inner core?
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
What are Earths layers from outermost going inward?
From most dense at the core to least dense proceeding outward.
What is the middle of the planet called?
The middle of a planet is generally called the 'Core'.
What happens when ahuge clouds of dust and gas begin to collapse?
When a large cloud of dust and gas begins to collapse due to gravity, it can undergo a process called protostar formation. As the cloud collapses, it heats up and starts spinning, eventually forming a dense core at its center. This core will continue to accumulate material and eventually become hot and dense enough to initiate nuclear fusion, becoming a star.
What is the most dense region of the earth called?
The Inner Core is the most dense part of the Earth. It is a solid core of iron and nickel.
What happens when a massive star cools and collapses?
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
How is neutron degenerate matter created?
Neutron stars are created when a massive star runs out of hydrogen to burn and become a supergiant. The supergiant will then explode and only leaves a core and a nebula. The dense core will then become a neutron star or a black hole.
What state of matter is a supernova?
A supernova is a highly energetic and explosive event that occurs when a star reaches the end of its life cycle. It involves a rapid and violent collapse of the star's core, resulting in a burst of energy and matter being expelled into space. During a supernova, the matter is in a highly energetic and dense state, transitioning from a combination of different states of matter including plasma.
What are the small dense remains of a high mass star?
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
What stars form from clouds of dust and gas is called?
Stars that form from clouds of dust and gas are called "protostars." These clouds, known as nebulae, collapse under their own gravity, leading to the formation of a dense core. As the core continues to contract, it heats up and eventually initiates nuclear fusion, marking the birth of a new star.
What is the dense lower part of the mantle is a physical layer called?
outer core
Which stars are composed of matter in which electrons have combined with protons?
Stars may collapse to such a degree, perhaps after a supernova, that, in the core, electrons are squashed into the nucleus, reacting with protons to form neutrons. A star of this collapsed state is called neutron stars.
Does Jupiter have a dense core of hydrogen and helium?
No, it has a dense rocky core in the middle!!
What are glowing cloud sections that will eventually become stars?
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
How long does it take for a massive star's core to become iron from silicon?
The process of core collapse to form iron from silicon in a massive star can occur in a matter of days to weeks. This phase, known as core-collapse supernova, is an explosive event where the iron core rapidly collapses and rebounds, leading to the synthesis of heavier elements.
