Front Back
A very low mass particle formed in solar fusion reactions that reacts only weakly with matter.
Neutrino
The state of heaving a balance between inflowing and outflowing heat.
Thermal equilibrium
The process, similar to conduction, by which energy moves from the solar core to the convective layer.
Radiative diffusion
The process that powers the sun and hydrogen bombs
Thermonuclear fusion
Dark areas on the sun that are cooler than the surrounding photosphere. a region in the photosphere where the sun's magnetic field erupts through the surface. is cooler and darker by comparison.
Sunspots
A fusion process in which protons bond together to ultimately form helium
Proton-proton chain
The relationship that describes how matter equates with energy
E=mc2
The state of having a balance between inward and outward pressures in a gas. when material has an unchanging pressure gradient. that is, the pressure is not the same throughout but whatever it is at any point, it is not changing with time.
Hydrostatic equilibrium
The 22 year period on the sun during which sunspots increase, decrease, change polarity, increase and decrease again
Sunspot cycle
The surface of the sun
Photosphere
The layer of the sun just above the photosphere
Chromosphere
A change in the appearance of the sun at the edge of the solar disk
Limb darkening
The high temperature outermost layer of the sun
Corona
When material is heated and moves taking the heat energy with it
Convection
Hot cells of gas that rise and fall in the photosphere
