    A Milky Way-like barred spiral galaxy at a redshift of 3
    The majority of massive disk galaxies in the local Universe show a stellar barred structure in their central regions, including our Milky Way 1,2. Bars are...

    A millisecond pulsar candidate in a 21-h orbit: 3FGL J0212.1+5320
    We present the discovery of a variable optical counterpart to the unidentified gamma-ray source 3FGL J0212.1+5320 and argue that this is a new compact binary...

    A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654
    We report the discovery and Doppler mass measurement of a 7.4 days 2.3 R ⊕ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high...

    A minor merger origin for stellar inner discs and rings in spiral galaxies
    Context. Observations have shown that inner discs and rings (IDs and IRs) are not preferably found in barred galaxies, which indicates that their formation may...

    A Misfired Outburst in the Neutron Star X-Ray Binary Centaurus X-4
    We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5 yr. This source has been in quiescence...

    A model for constructing artificial integrated spectral lines and their Fourier transform properties relevant to the search for differential rotation of stars
    A model is given for constructing artificial integrated spectral lines which allows the inclusion of all effects relevant to the synthesis of these lines by...

    A Modified Kwee─Van Woerden Method for Eclipse Minimum Timing with Reliable Error Estimates
    The Kwee - van Woerden (KvW) method for the determination of eclipse minimum times has been a staple in eclipsing binary research for decades, due its...

    A modified Milne-Eddington approximation for a qualitative interpretation of chromospheric spectral lines
    Context. The Milne-Eddington approximation provides an analytic and simple solution to the radiative transfer equation. It can be easily implemented in...

    A modified χ2-test for cosmic microwave background analyses
    We present a new general procedure for determining a given set of quantities. To this end, we define a certain statistic, which we call `modified χ2' (χ2M)...
