Layers of the Sun (~ 75% Hydrogen ~ 25% Helium)
Layers of the Sun (~ 75% Hydrogen ~ 25% Helium)

... In solar astronomy, the innermost part of the Sun, where energy is generated by nuclear reactions (fusion). The Sun's core has a tremendously high temperature and pressure. The temperature is roughly 15 million °C. At this temperature, nuclear fusion occurs, turning four hydrogen nuclei into a singl ...

Stellar Evolution Diagram Answer Key:

... A supergiant star forms when the main sequence star runs out of Hydrogen to fuse in the core. This causes the star to collapse. When the M.S. star collapses- the increase in pressure causes and increase in temperatures that are high enough to fuse Helium into larger atoms up to Carbon atoms. Only Gi ...

... A single such measurement can be very fast, so this method is especially suited for short-lived nuclides. The alternative method comprises the measurement of the image current (~10 –15 A) induced in the trap electrodes by the oscillating ion. This allows to determine the frequency by a single measur ...

... Why? Think crudely about the electrons as "trying" to fit themselves into a MaxwellBoltzmann distribution, but failing because there are only so many states available in position-momentum space. Specifically, the exclusion principle limits them on the low-momentum end, so a degenerate gas will tend ...

... In general, the opacity of a star is proportional to its metal abundance (due to bound-free transitions and electrons supplied to H-.) The lower the metal abundance, the smaller the opacity, the less energy is trapped in the star doing work, the smaller the star, and therefore the hotter the star. T ...

... X-ray emission from clusters of galaxies: thermal bremsstrahlung The notion that the space between galaxies in a cluster must be filled with some material which gravitates but does not emit light (at least, in the optical) was first proposed by Zwicky in the 1930’s. His observations showed that th ...

From the formula above, it is immediately clear that a contraction of the star under its own gravity will further raise the central temperature.

Fusor



A fusor is a device that uses an electric field to heat ions to conditions suitable for nuclear fusion. The machine has a voltage between two metal cages inside a vacuum. Positive ions fall down this voltage drop, building up speed. If they collide in the center, they can fuse. This is a type of Inertial electrostatic confinement device.A Farnsworth–Hirsch fusor is the most common type of fusor. This design came from work by Philo T. Farnsworth (in 1964) and Robert L. Hirsch in 1967. A variant of fusor had been proposed previously by William Elmore, James L. Tuck, and Ken Watson at the Los Alamos National Laboratory though they never built the machine.Fusors have been built by various institutions. These include academic institutions such as the University of Wisconsin–Madison, the Massachusetts Institute of Technology and government entities, such as the Atomic Energy Organization of Iran and the Turkish Atomic Energy Authority. Fusors have also been developed commercially, as sources for neutrons by DaimlerChrysler Aerospace and as a method for generating medical isotopes. Fusors have also become very popular for hobbyists and amateurs. A growing number of amateurs have performed nuclear fusion using simple fusor machines.
