I'm a sci-fi writer, and I have a question regarding a hypothetical planet that orbits an A-class or B-class Star.
Assuming Rayleigh Scattering occurs roughly the same way on this planet as it does on Earth, what colors would we see at Sunrise and Sunset?
I understand that what colours we see from our sun comes from the Rayleigh Scattering, but seeing as it's sci-fi I'm writing, I need a plausible colour scheme to use for my new planet. The Planet has a breathable atmosphere not too different to Earth, so for the sake of the argument, I'm assuming that the Rayleigh Scattering would occur roughly the same way, but my physics knowledge is sadly lacking in this area, and the Wikipedia article only refers to our own G-class Sun.
On that note, would the Sky still appear Blue, from an A-class or B-class Star? Or would the Rayleigh scattering trigger a completely different colour of the sky? Is there no 'right answer' when it comes to what sunrise/sunset/sky would look like on a distant planet?
