Question

the Sun displays limb darkening. For all the planets in the solar system, predict whether or not you expect to also observe limb darkening . Explain your predictions.

Answer 1

* Limb darkening phenomenon Comes under astrophysics,

* Limb darkening is an optical effect  seen in stars and  the Sun,  where the central part of the disk appears brighter than the edge, or limb.

* Limb darkening, gradual decrease in brightness of the disk of the Sun or of another star as observed from its centre to its edge, or limb.

* This phenomenon is readily apparent in photographs of the Sun

* Such limb darkening occurs because the solar atmosphere increases in temperature with depth.

*   At the centre of the solar disk, an observer sees the deepest and warmest layers that emit the most light.

*   At the limb, only the upper, cooler layers that produce less light can be seen.

*   Observations of solar limb darkening are used to determine the temperature structure of the Sun’s atmosphere.

*   Information derived from such observations is applied in studying other stars.

* A filtered image of the Sun in visible light, showing the limb-darkening effect as a dimmer luminosity towards the edge or limb of the solar disk.

* The effect is more pronounced at the blue end of the spectrum and less pronounced at the red.

* Limb Darkening of the sun

* As per the studies limb darkening may be limited to sun and brightest stars.
