Description
The effect produced by a sharp discontinuity in the upper boundary of the conductosphere is analysed in order to evaluate the distortions introduced in geomagnetic variation profiles in the long-period range of the spectra. To do so, a conformal mapping method is applied and the results are compared with the ones obtained in the case of lateral homogeneity. This model is also applied to interpret the internal part of the geomagnetic daily variations at the equatorial zones of Peru and central Africa.

    Expanded Sample of Small Magellanic Cloud Ultraviolet Dust Extinction Curves: Correlations between the 2175 Å Bump, q <SUB>PAH</SUB>, Ultraviolet Extinction Shape, and N(H I)/A(V)
    The Small Magellanic Cloud (SMC) shows a large variation in ultraviolet (UV) dust extinction curves, ranging from Milky Way (MW) like to significantly steeper curves with no detectable 2175 Å bump. This result is based on a sample of only nine sight lines. From Hubble Space Telescope Space Telescope Imaging Spectrograph and IUE spectra of OB stars

    Age of Massive Galaxies at Redshift 8
    Recent James Webb Space Telescope data analyses have shown that massive red galaxies existed at redshifts z ≳ 6, a discovery that is difficult to understand in the context of standard cosmology (ΛCDM). Here, we analyze these observations more deeply, by fitting a stellar population model to the optical and near-infrared photometric data. These fits

    Early Results from the HUMDRUM Survey: A Small, Earth-mass Planet Orbits TOI-1450A
    M-dwarf stars provide us with an ideal opportunity to study nearby small planets. The HUnting for M Dwarf Rocky planets Using MAROON-X (HUMDRUM) survey uses the MAROON-X spectrograph, which is ideally suited to studying these stars, to measure precise masses of a volume-limited (<30 pc) sample of transiting M-dwarf planets. TOI-1450 is a nearby (22
