    Detection of Fe and evidence for TiO in the dayside emission spectrum of WASP-33b
    Context. Theoretical studies predict the presence of thermal inversions in the atmosphere of highly irradiated gas giant planets. Recent observations have...

    Detection of Fe and Ti on the dayside of the ultrahot Jupiter MASCARA-1b with CARMENES
    Ultrahot Jupiters are a type of gaseous exoplanet that orbit extremely close to their host star, resulting in significantly high equilibrium temperatures. In...

    Detection of Fe I and Fe II in the atmosphere of MASCARA-2b using a cross-correlation method
    Ultra-hot Jupiters are gas giants planets whose dayside temperature is greater than 2200 K as a consequence of the strong irradiation received from the host...

    Detection of frequency spacings in the young O-type binary HD 46149 from CoRoT photometry
    Aims: Using the CoRoT space based photometry of the O-type binary HD 46149, stellar atmospheric effects related to rotation can be separated from pulsations...

    Detection of iron emission lines and a temperature inversion on the dayside of the ultra-hot Jupiter KELT-20b
    Ultra-hot Jupiters (UHJs) are gas giants with very high equilibrium temperatures. In recent years, multiple chemical species, including various atoms and ions...

    Detection of Na, K, and Hα absorption in the atmosphere of WASP-52b using ESPRESSO
    WASP-52b is a low-density hot Jupiter orbiting a moderately active K2V star. Previous low-resolution studies have revealed a cloudy atmosphere and found atomic...
