    Merging plasmoids and nanojet-like ejections in a coronal current sheet
    Context. Forced magnetic reconnection is triggered by external perturbations, which are ubiquitous in the solar corona. This process plays a crucial role in the...

    Metal-THINGS: Gas metallicity gradients in nearby galaxies
    Aims. This paper explores and analyses the gas metallicity gradients in a sample of 25 nearby galaxies using new integral field spectroscopy observations from...

    Metallicities in M dwarfs: Investigating different determination techniques
    Deriving metallicities for solar-like stars follows well-established methods, but for cooler stars such as M dwarfs, the determination is much more complicated...

    Metallicity dependence of turbulent pressure and macroturbulence in stellar envelopes
    Macroturbulence, introduced as a fudge to reproduce the width and shape of stellar absorption lines, reflects gas motions in stellar atmospheres. While in cool...

    Metallicity distribution of red giants in the Inner Galaxy from near infrared spectra
    Context: The existence in the Milky Way of either a long thin bar with a half length of 4.5 kpc and a position angle of around 45° with respect to the Sun...

    Metallicity effect on stellar granulation detected from oscillating red giants in open clusters
    Context. The effect of metallicity on the granulation activity in stars, and hence on the convective motions in general, is still poorly understood. Available...

    Metallicity, temperature, and gravity scales of M subdwarfs
    Aims: The aim of the project is to define metallicity/gravity/temperature scales for different spectral types of metal-poor M dwarfs. Methods: We obtained...

    MHD seismology of coronal loops using the period and damping of quasi-mode kink oscillations
    Aims:We combine the magnetohydrodynamic (MHD) theory of resonantly damped quasi-mode kink oscillations with observational estimates of the period and damping of...

    MHDSTS: a new explicit numerical scheme for simulations of partially ionised solar plasma
    The interaction of plasma with magnetic field in the partially ionised solar atmosphere is frequently modelled via a single-fluid approximation, which is valid...
