    Simulation of a flux emergence event and comparison with observations by Hinode
    Aims: We study the observational signature of flux emergence in the photosphere using synthetic data from a 3D MHD simulation of the emergence of a twisted flux...

    Simulation of resonance scattering helioseismometer signals from spatially resolved images: Application to the GOLF instrument on SOHO
    A step in the analysis of the data from the GOLF (Global Oscillations at Low Frequency) instrument on SOHO (SOlar and Heliospheric Observatory, an ESA/NASA...

    Simulations of the Biermann battery mechanism in two-fluid partially ionised plasmas
    Context. In the absence of an initial seed, the Biermann battery term of a non-ideal induction equation acts as a source that generates weak magnetic fields...

    Simultaneous longitudinal and transverse oscillations in filament threads after a failed eruption
    Context. Longitudinal and transverse oscillations are frequently observed in the solar prominences and/or filaments. These oscillations are excited by a large...

    Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008
    The blazar PG 1553+113 is a well known TeV γ-ray emitter. In this paper we determine its spectral energy distribution through simultaneous multi-frequency data...

    Simultaneous NICER and NuSTAR observations of the ultraluminous source NGC 4190 ULX-1
    Aims: We present an X-ray analysis of three different XMM-Newton observations together with simultaneous NICER and NuSTAR observations of the ultraluminous X...

    Simultaneous optical and near-infrared linear spectropolarimetry of the earthshine
    Aims: We aim to extend our current observational understanding of the integrated planet Earth spectropolarimetry from the optical to the near-infrared...

    Simultaneous optical and X-ray observations of flares and rotational modulation on the RS CVn binary HR 1099 (V711 Tau) from the MUSICOS 1998 campaign
    We present simultaneous and continuous observations of the Hα, Hβ, He I D3, Na I D1, D2 doublet and the Ca II H & K lines for the RS CVn system HR 1099. The...

    Simultaneous photometric and CARMENES spectroscopic monitoring of fast-rotating M dwarf GJ 3270. Discovery of a post-flare corotating feature
    Context. Active M dwarfs frequently exhibit large flares, which can pose an existential threat to the habitability of any planet in orbit in addition to making...
