HAT-P-23

[7] The star is enriched in heavy elements, having about 140% amount of metals compared to solar abundance.

In 2019, the HAT-P-23 star has received a proper name Moriah and planet HAT-P-23b - Jebus at an international NameExoWorlds contest.

[4] It has a measured dayside temperature of 2154±90 K.[9] The planet is believed to be on an unstable orbit, and expected to be engulfed by its parent star about 7.5+2.9−1.8 million years from now,[4] although timing measurements of multiple transits since the discovery have been unable to detect any reduction in the orbital period.

[5][10] The planetary orbit is probably aligned with the equatorial plane of the star, misalignment equal to 15±22°.

[12] The atmosphere is mostly devoid of clouds, and shows tentatively a presence of Titanium(II) oxide.
