Astronomers Observe The Limb Darkening Effect On Nearby Stars
The edge of the Sun appears darker than its central region. This effect is known as limb darkening and tells us about the solar atmosphere. This same limb darkening effect has now been observed on several nearby stars and could help us improve our understanding of stellar atmospheres.
Astronomers of the Center for High Angular Resolution (CHARA) made observations that confirm the darkening effect on the edges of 31 nearby stars. This phenomenon, known as the darkening effect, is a characteristic of the stellar atmosphere that affects the perceived luminosity in the extremities of the stars. What is the darkening effect The darkening effect refers to the decrease of the luminosity observed on the edges of a celestial body, com…
