Just as a low-mass main sequence star runs out of fuel in its core it actually becomes brighter How is this possible?
The core contracts, raising the temperature and increasing the size of the region of hydrogen shell-burning.
The energy source of stars is primarily associated with?
hydrogen fusion in the core. eventually runs out of hydrogen in the core and hydrogen fusion moves to the shell whilst the core contracts (star expands into red giant)...star leaves the main sequence.
What would happen if the sun had no core?
The core is necessary for a star's existence, it's the engine that keeps it from collapsing. When this engine runs out of fuel or its fuel vanishes, gravity overcomes and contracts the star until matter from the radiative zone is compressed enough to start fusing hydrogen again to counterbalance gravity.
What is the fuel for stars?
Fusion, 2 hydrogen atoms turning into one Helium atoms continuously. (until the hydrogen runs out)
What happens when the first stage of the multistage rocket runs out of fuel?
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
Just as a low-mass main sequence star runs out of fuel in its core it actually becomes brighter How is this possible?
The core contracts, raising the temperature and increasing the size of the region of hydrogen shell-burning.
When a low mass star first runs short of hydrogen in its core it becomes brighter because?
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
The energy source of stars is primarily associated with?
hydrogen fusion in the core. eventually runs out of hydrogen in the core and hydrogen fusion moves to the shell whilst the core contracts (star expands into red giant)...star leaves the main sequence.
How do you increase the eficincy of a machine?
well if it runs on fuel then use hydrogen based fuel
When a star runs out if hydrogen what does it use as fuel source?
helium

Is hydogen a fuel?
yes hydrogen is a fuel because I'm making a car that runs in hydrogen fuel.hydogen fuel is from distilled water then the hydoen is separated from the water.then there you go,hydogen fuel.
What is the star Rigel's core made of?
Hydrogen and Helium, with the former decreasing and the latter increasing. Rigel is fusing H into He at a prodigious rate and in a million years or so will start to collapse as its fuel runs out.
What is formed when a red supergiant runs out of fuel at its core?
black hole
What happens when you bypass heater core?
you have no heat and car runs normal
