Definition of photosphere in English:
photosphere
noun ˈfəʊtəsfɪəˈfoʊdəˌsfɪr
Astronomy The luminous envelope of a star from which its light and heat radiate.
Example sentencesExamples
- The trip from the radiation zone to the photosphere - the yellowish-white sphere of light that we see - takes about one week.
- Typically the corona is a million times fainter than the solar surface, which is why it cannot be seen except when the photosphere is mostly extinguished.
- The answer comes from a fourth line of evidence on the deep-Earth composition: cosmic abundances of the elements deduced from analyses of chondritic meteorites and the solar photosphere.
- Observing the solar photosphere in white light is traditionally carried out with neutral density filters.
- The rotated elliptical shell could explain the polarization angle, but failed to match a feature in the supernova's flux that suggested an uneven absorption of light from the photosphere.
Derivatives
adjective fəʊtəˈsfɛrɪk
Astronomy We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary.
Example sentencesExamples
- We can, however, extrapolate the photospheric magnetic field into the corona.
