Limb-darkening curves exhibit different behaviors at varying wavelengths, with shorter wavelengths (around 4000 Angstroms) typically showing a steeper fall-off compared to longer wavelengths (around 7000 Angstroms). This difference is attributed to the varying opacity and temperature gradients in stellar atmospheres. Research indicates that the effects of limb darkening are more pronounced in the ultraviolet and blue regions of the spectrum. Observational data and theoretical models support these findings, highlighting the importance of wavelength in understanding stellar characteristics. Understanding these differences is crucial for accurate modeling in astrophysics.

TL;DR: Wavelengths of lets say 4000 Angstroms and 7000 angstroms.

Does the limb-darkening curve fall off faster at shorter wavelengths or at longer wavelengths?

Thread 'Looking for info about the Sombrero Galaxy'

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
