    Examining the orbital decay targets KELT-9 b, KELT-16 b, and WASP-4b, and the transit-timing variations of HD 97658 b
    Context. Tidal orbital decay is suspected to occur for hot Jupiters in particular, with the only observationally confirmed case of this being WASP-12b. By...

    Excitation mechanisms of C II optical permitted lines in ionized nebulae
    Context. Carbon is the fourth most abundant element in the universe and its distribution is critical to understanding stellar evolution and nucleosynthesis. In...

    Exoplanet hosts reveal lithium depletion. Results from a homogeneous statistical analysis
    Aims: We study the impact of the presence of planets on the lithium abundance of host stars and evaluate the previous claim that planet hosts exhibit lithium...

    Expanding on the fundamental metallicity relation in dwarf galaxies with MUSE
    The mass-metallicity relation (MZR) represents one of the most important scaling relations in the context of galaxy evolution, comprising a positive correlation...

    Expansive components in H II regions
    We study the presence of low intensity high velocity components, which we have termed wing features in the integrated Hα emission line profiles of the H II...

    Explanation of the activity sensitivity of Mn I 5394.7 Å
    There is a long-standing debate why the Mn i 5394.7 Å line in the solar irradiance spectrum brightens more at higher activity than other photospheric lines. The...

    Exploration of long-period oscillations in an Hα prominence
    Context. In previous work, we studied a prominence which appeared like a tornado in a movie made from 193 Å filtergrams obtained with the Atmospheric Imaging...

    Exploring circumstellar effects on the lithium and calcium abundances in massive Galactic O-rich AGB stars
    Context. We previously explored the circumstellar effects on Rb and Zr abundances in a sample (21) of massive Galactic O-rich asymptotic giant branch (AGB)...

    Exploring the circumstellar environment of the young eruptive star V2492 Cygni
    Context. V2492 Cyg is a young eruptive star that went into outburst in 2010. The near-infrared color changes observed since the outburst peak suggest that the...
