    Detection of Ionized Calcium in the Atmosphere of the Ultra-hot Jupiter KELT-9b
    With a dayside temperature in excess of 4500 K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a...

    High-resolution Emission Spectroscopy of the Ultrahot Jupiter KELT-9b: Little Variation in Day- and Nightside Emission Line Contrasts
    The transmission spectrum of the ultrahot Jupiter KELT-9b (T eq ~ 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular...
