Reminds me of this Vernor Vinge novel: https://en.wikipedia.org/wiki/A_Deepness_in_the_Sky

Set around a star that alternates between bright and dim, with a species that hibernates during the dim periods.

Have you read Three body problem? Park of that is about a species that likes on a planet in a (chaotic) three star system. They alternate between intense heat and freezing darkness with the occasional "golden age". The books are more earth centred but very good...
