<p>WD 1856b is not more massive than the star it orbits. The radius of WD 1856b is much larger than its star because its star is a white dwarf; but WD 1856b is much less massive. That gives the star a diameter of a bit larger than Earth while the planet's size is about that of Jupiter.</p>

I hope you don't mind my edit. I was a bit confused on first reading the sentence of which statement referred to what. Please revert, if you disagree.

<p>WD 1856 has smaller mass than WD 1856b. So how WD1856 making
WD 1856b revolve in the orbit? Its clear violating space-time curvature.</p>

WD 1856b is not more massive than the star it orbits. The radius of WD 1856b is much larger than its star because its star is a white dwarf; but WD 1856b is much less massive. That gives the star a diameter of a bit larger than Earth while the planet's size is about that of Jupiter.

[The star, WD 1856+534](https://www.dailymail.co.uk/sciencetech/article-8739723/Jupiter-sized-planet-orbiting-distant-white-dwarf-star.html) is about 1/2 the mass of our Sun or about 500 Jupiter masses. The planet is listed as "less than 13.8" Jupiter masses, so the star is at minimum over 30 times the planet's mass.
