Addison-Wesley
Addison–Wesley is an American publisher of textbooks and computer literature.
See Photosphere and Addison-Wesley
Ancient Greek
Ancient Greek (Ἑλληνῐκή) includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC.
See Photosphere and Ancient Greek
Convection cell
In fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas.
See Photosphere and Convection cell
Cubic metre
The cubic metre (in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the unit of volume in the International System of Units (SI).
See Photosphere and Cubic metre
Density
Density (volumetric mass density or specific mass) is a substance's mass per unit of volume.
Helium
Helium (from lit) is a chemical element; it has symbol He and atomic number 2.
Hydrogen
Hydrogen is a chemical element; it has symbol H and atomic number 1.
Kilogram
The kilogram (also kilogramme) is the base unit of mass in the International System of Units (SI), having the unit symbol kg.
Kilometre
The kilometre (SI symbol: km; or), spelt kilometer in American English and Philippine English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for). It is the preferred measurement unit to express distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is used.
Magnetic field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
See Photosphere and Magnetic field
Max Planck Institute for Solar System Research
The Max Planck Institute for Solar System Research (abbreviation: MPS; Max-Planck-Institut für Sonnensystemforschung) is a research institute in astronomy and astrophysics located in Göttingen, Germany, where it relocated in February 2014 from the nearby village of Lindau.
See Photosphere and Max Planck Institute for Solar System Research
Metallicity
In astronomy, metallicity is the abundance of elements present in an object that are heavier than hydrogen and helium. Photosphere and metallicity are stellar astronomy.
See Photosphere and Metallicity
NASA
The National Aeronautics and Space Administration (NASA) is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research.
Neutron star
A neutron star is the collapsed core of a massive supergiant star.
See Photosphere and Neutron star
Optical depth
In physics, optical depth or optical thickness is the natural logarithm of the ratio of incident to transmitted radiant power through a material.
See Photosphere and Optical depth
Plasma (physics)
Plasma is one of four fundamental states of matter (the other three being solid, liquid, and gas) characterized by the presence of a significant portion of charged particles in any combination of ions or electrons.
See Photosphere and Plasma (physics)
Solar facula
Solar faculae are bright spots in the photosphere that form in the canyons between solar granules, short-lived convection cells several thousand kilometers across that constantly form and dissipate over timescales of several minutes.
See Photosphere and Solar facula
Solar granule
In solar physics and observation, granules are convection cells in the Sun's photosphere.
See Photosphere and Solar granule
Star
A star is a luminous spheroid of plasma held together by self-gravity. Photosphere and star are Light sources and stellar astronomy.
Starspot
Starspots are stellar phenomena, so-named by analogy with sunspots.
Stefan–Boltzmann law
The Stefan–Boltzmann law, also known as Stefan's law, describes the intensity of the thermal radiation emitted by matter in terms of that matter's temperature.
See Photosphere and Stefan–Boltzmann law
Sun
The Sun is the star at the center of the Solar System. Photosphere and Sun are Light sources.
Sunspot
Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area.
Supergranulation
In solar physics and observation, supergranulation is a pattern of convection cells in the Sun's photosphere.
See Photosphere and Supergranulation
Wavelength
In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats.
See Photosphere and Wavelength
