We present the discovery by the WASP-South survey, in close collaboration with the Euler and TRAPPIST telescopes, of WASP-121 b, a new remarkable shortperiod transiting hot Jupiter, whose planetary nature has been statistically validated by the PASTIS software. The planet has a mass of 1:183 +0:064 0:062 MJup, a radius of 1.865 0.044 RJup, and transits every 1:2749255 +0:0000020 0:0000025 days an ac

• From thermal dissociation to condensation in the atmospheres of ultra hot Jupiters: WASP-121b in context (2018, background): “The transit of the planet was observed from groundbased observatories (Trappist and EulerCam, see Delrez et al. 2016) and with HST/WFC3 (Evans et al. 2016), whereas the eclipse of the planet was observed with HST/WFC3, Trappist, and Spitzer (Evans et al. 2017).”
• The Hubble Space Telescope PanCET Program: Exospheric Mg ii and Fe ii in the Near-ultraviolet Transmission Spectrum of WASP-121b Using Jitter Decorrelation (2019, methodology): “WASP-121b is an ultra-hot Jupiter discovered by Delrez et al. (2016), with a dayside equilibrium temperature above 2400 K.”
• DETECTION OF H2O AND EVIDENCE FOR TiO/VO IN AN ULTRA-HOT EXOPLANET ATMOSPHERE (2016, methodology): “However, the fact that WASP-121b has a lower equilibrium temperature (Teq ∼ 2400 K) than WASP-12b, and yet shows evidence for TiO/VO absorption at low pressures, indicates that additional factors are at play.”
