True Mass and Atmospheric Composition of the Nontransiting Hot Jupiter HD 143105 b

We present Keck/KPIC Phase II K -band observations of the nontransiting hot Jupiter HD 143105 b. Using a cross-correlation approach, we make the first detection of the planetary atmosphere at ${K}_{{\rm{p}}}=18{5}_{-13}^{+11}$ km s ^−1 and an inferior conjunction time 2.5 hr before the previously pu...
