Yellow main sequence stars are stereotypically prima-donnas. Favored over pale stars for their ubiquity and orange stars for their less temperamental habits, these relatively rare stars are generally considered almost bland. What choice, then, is there for such a star- one considered generally boring but always hospitable? They will delight in their planets, especially those who harbor some form of life. I have heard some even strain to provoke their planets into more odd or appealing forms, though what methods could be used for this are beyond me.
Of course, the stereotype fails. Yellow stars are still fairly long-lived, and though stars change slowly I suspect the stereotype only arises from the joy that comes with the advent of life. Likewise, every planet has some uniqueness to it- certainly enough for a star to notice and take pleasure in. Yellow stars in multi-star systems are generally heavy enough that their companions are lighter redder stars, and these are stereotypically doting....
