Abstract
We report the discovery and tomographic detection of WASP-174b, a planet with a near-grazing
transit on a 4.23-d orbit around a V= 11.9, F6V star with [Fe/H] = 0.09 ± 0.09. The planet is
in a moderately misaligned orbit with a sky-projected spin–orbit angle of λ = 31◦ ± 1◦. This is
in agreement with the known tendency for orbits around hotter stars to be misaligned. Owing
to the grazing transit, the planet’s radius is uncertain with a possible range of 0.8–1.8 RJup.
The planet’s mass has an upper limit of 1.3 MJup. WASP-174 is the faintest hot-Jupiter system
so far confirmed by tomographic means.
