An irradiated-Jupiter analogue hotter than the Sun
https://www.nature.com/articles/s41550-023-02048-z?utm_campaign=natastronTWT
"Here we report observations revealing an extremely irradiated low-mass companion to the hot white dwarf WD 0032?317. Our analysis indicates a day-side temperature of ~8,000 K, and a day-to-night temperature difference of ~6,000 K."
So how that irradiated-Jupiter could be hotter than the Sun?

Because WD 0032?317 is a lot hotter than the sun.
It has a surface temperature of about 37000K rather than about 5700K
And a white dwarf is small, so a planet could be nearer to it.

Bored Chemist hit the nail on the head. I hope this isn't going to turn into a science denial post.
