Access through your institution Buy or subscribe High-resolution spectroscopy has by now become a staple in the arsenal of techniques used for the characterization of exoplanetary


atmospheres, as it allows the discovery of many atomic and ionic species in hot exoplanets. Zewen Jiang and colleagues expand the chemical catalogue further with the identification of


previously undetected elements with high atomic numbers. Jiang et al. observed the ultra-hot Jupiter MASCARA-4 b with two transits obtained by the ESPRESSO/VLT instrument, specifically


targeting the signatures of heavy elements. In addition to the confirmation of elements found in previous surveys, there are a few intriguing discoveries: a robust detection of rubidium


(Rb), samarium (Sm) and the heavy ions Ti+ and Ba+, and the tentative detection of Sc+. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through
