It depends how you define and calculate what the habitable zone is. Please provide more details or examples.

Where does "When calculating the habitable zone of a star, the minimum and maximum stellar flux limits compared to Earth seem to be larger for stars with lower temperatures" come from? If you can cite the source and provide some context it will help with answers.

I mean that according to this
https://personal.ems.psu.edu/~ruk15/planets/
It seems if the luminosity of a star remains the same, the habitable zone would be further out if the start had a lower temperature and closer in if the star had a higher temperature, if the luminosity stays the exact same. Why is that?

@SussusAmogus you should rewrite your question and you should highlight that link in the beginning.

Why are the flux limits larger for low-temperature stars?

When calculating the habitable zone of a star, the minimum and maximum stellar flux limits compared to Earth seem to be larger for stars with lower temperatures. Why is that?
