    Measuring stellar surface rotation and activity with the PLATO mission: I. Strategy and application to simulated light curves
    The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands...

    MELCHIORS. The Mercator Library of High Resolution Stellar Spectroscopy
    Aims: Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a...

    Membership, rotation, and lithium abundances in the open clusters NGC 2451 A and B
    High-resolution spectra of 30 late-type and 9 early-type candidate members of the young (˜50-80 Myr) open clusters NGC 2451 A and B have been analyzed in order...

    Menzel 3: Dissecting the ant
    The structure and kinematics of the bipolar nebula Mz 3 have been investigated by means of HST, CTIO and ESO images and spectra. At least four distinct outflows...

    Merger induced clump formation in distant infrared luminous starburst galaxies
    While the formation of stellar clumps in distant galaxies is usually attributed to gravitational violent disk instabilities, we show here that major mergers...

    Merging in the common envelope and the origin of early R-type stars
    Context. Binary systems experiencing one or two common envelope episodes during the red giant branch or the Hertzsprung gap phases can produce a single star...

    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...

    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...
