    Evaluating the chromospheric structure model of AD Leo using RH 1.5D and magnetic field data
    Context. The interplay between surface magnetic topology and chromospheric heating in active M dwarfs remains poorly constrained, limiting our understanding of...

    Evershed flow observed in neutral and singly ionized iron lines
    The amplitudes of the Evershed flow are measured using pairs of carefully selected Fe i and Fe ii spectral lines that are close in wavelength and registered...

    Evidence for a deficit of young and old stars in the Milky Way inner in-plane disc
    We give independent proof of the deficit of stars in the in-plane central disc (2

    Evidence for a large stellar bar in the Low Surface Brightness galaxy UGC 7321
    Late-type spiral galaxies are thought to be the dynamically simplest type of disk galaxy and our understanding of their properties plays a key role in galaxy...

    Evidence for a metal-poor population in the inner Galactic bulge
    The inner Galactic bulge has, until recently, been avoided in chemical evolution studies because of extreme extinction and stellar crowding. Large, near-IR...

    Evidence for binarity in the bipolar planetary nebulae A 79, He 2-428 and M 1-91
    We present low and high resolution long-slit spectra of three bipolar planetary nebulae (PNe) with bright central cores: A 79, He 2-428 and M 1-91. He 2-428 and...

    Evidence for globular cluster collapse after a dwarf-dwarf merger: A potential nuclear star cluster in formation
    Direct observational evidence for the creation of nuclear star clusters (NSCs) is needed to support the proposed scenarios for their formation. We analysed the...

    Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8−162
    We present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope across the bright discovery outburst of the black hole candidate Swift J1727...

    Evidence for nonlinear resonant mode coupling in the β Cephei star HD 180642 (V1449 Aquilae) from CoRoT photometry
    Context: We present the CoRoT light curve of the β Cep star HD 180642, assembled during the first long run of the space mission, as well as archival single-band...
