Description
We report a spin–orbit misalignment for the hot-Jupiter HATS-14b, measuring a projected orbital obliquity of $| \lambda | ={76}_{-5}^{+4}\;^\circ .$ HATS-14b orbits a high metallicity, 5400 K G dwarf in a relatively short period orbit of 2.8 days. This obliquity was measured via the Rossiter–McLaughlin effect, obtained with observations from Keck-HIRES. The velocities were extracted using a novel technique, optimized for low signal-to-noise spectra, achieving a high precision of...[Show more]
