    Exact Semianalytical Calculation of Rotation Curves with Bekenstein-Milgrom Nonrelativistic MOND
    Astronomers derive MOdified Newtonian Dynamics (MOND) rotation curves using the simple algebraic rule of calculating the acceleration as equal to the Newtonian...

    Excitation of emission lines by fluorescence and recombination in IC 418
    We compare calculated intensities of lines of C II, N I, N II, O I and O II with a published deep spectroscopic survey of IC 418. Our calculations use a self...

    ExoMol molecular line lists - XXXIII. The spectrum of Titanium Oxide
    Accurate line lists are crucial for correctly modelling a variety of astrophysical phenomena, including stellar photospheres and the atmospheres of extrasolar...

    Explaining the chemical trajectories of accreted and in-situ halo stars of the Milky Way
    The Milky Way underwent its last significant merger ten billion years ago, when the Gaia-Enceladus-Sausage (GES) was accreted. Accreted GES stars and progenitor...

    Exploring Anticorrelations and Light Element Variations in Northern Globular Clusters Observed by the APOGEE Survey
    We investigate the light-element behavior of red giant stars in northern globular clusters (GCs) observed by the SDSS-III Apache Point Observatory Galactic...

    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 nine simultaneously occurring transients on April 12th 1950
    Nine point sources appeared within half an hour on a region within ∼? 10 arcmin of a red-sensitive photographic plate taken in April 1950 as part of the...

    Exploring the effects of high-velocity flows in abundance determinations in H II regions: bidimensional spectroscopy of HH 204 in the Orion nebula
    We present results from integral field optical spectroscopy with the Potsdam Multi-Aperture Spectrograph of the Herbig-Haro (HH) object HH 204, with a spatial...

    Exploring the Galactic Warp through Asymmetries in the Kinematics of the Galactic Disk
    Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on...
