| We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary. |
|
| We can, however, extrapolate the photospheric magnetic field into the corona. |
|
| Later it was found that there had been errors in prior photospheric determinations. |
|
| Joking aside, a low photospheric oxygen abundance is incompatible with the structure of the solar interior inferred from helioseismology. |
|
| The photospheric magnetic fields extend up into the atmosphere, where the supergranular pattern dominates the conducting gas. |
|
| Grotrian hypothesized that coronal light consists of photospheric light that has been scattered toward Earth by free electrons in the corona. |
|
| He noticed that, although coronal light had the same distribution of colours as light from the solar surface the photosphere it lacked the absorption lines observed in photospheric light. |
|
| A comparison made over more than a solar activity cycle show that there is indeed a linear correlation between the 10.7cm Solar Flux and the total photospheric magnetic flux in active regions. |
|
| Line asymmetries are generated by convective motions in stellar atmospheres, especially when the convective zone reaches high photospheric levels, indeed the case for the metal-poor turn-off stars in which 6Li was found. |
|
| However, the spectroscopic determination of the solar oxygen abundance is not an easy task: very few atomic lines are available in the solar photospheric spectrum, and most of them are blended with lines of other elements. |
|
| Young also believed that the polarization was due to the scattering of photospheric light by small particles. |
|
| Near disk center, the Coronal Cells looked like photospheric granules with bright centers and dark, narrow intercellular lanes. |
|
| Because density decreases with height more rapidly than magnetic field strength, the magnetic field dominates the chromospheric structure, which reflects the extension of the photospheric magnetic fields. |
|
| These might arise from mechanical effects for example, selective radiation pressure or photospheric diffusion and element separation rather than from nuclear effects. |
