    Multiband calibration of an all-sky sample of AGN fields--extending Landolt's standards to V = 19
    We describe the first results of a program to extend the Landolt calibration standards to at least V=19 mag and to calibrate fields separated from the celestial...

    Multicolour photometry for exoplanet candidate validation
    Context. The TESS and PLATO missions are expected to find vast numbers of new transiting planet candidates. However, only a fraction of these candidates will be...

    Multiple Stellar Populations in 47 Tucanae
    We use Hubble Space Telescope (HST) and ground-based imaging to study the multiple populations of 47 Tucanae (47 Tuc), combining high-precision photometry with...

    Multiple stellar populations in Magellanic Cloud clusters - VI. A survey of multiple sequences and Be stars in young clusters
    The split main sequences (MSs) and extended MS turnoffs (eMSTOs) detected in a few young clusters have demonstrated that these stellar systems host multiple...

    Multiple stellar populations in Magellanic Cloud clusters – V. The split main sequence of the young cluster NGC 1866
    One of the most unexpected results in the field of stellar populations of the last few years is the discovery that some Magellanic Cloud globular clusters...

    Multiple Stokes I inversions for inferring magnetic fields in the spectral range around Cr I 5782 Å
    Aims: In this work, we explore the spectral window containing Fraunhofer lines formed in the solar photosphere, around the magnetically sensitive Cr I lines at...

    Multiple water band detections in the CARMENES near-infrared transmission spectrum of HD 189733 b
    Aims: We explore the capabilities of CARMENES for characterising hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4...

    Multiplicity of cool dwarfs
    Multiple systems have long been used to probe the origin and evolution of stars of all masses. Only in the past 10-15 years have such studies been extended to...

    Multisite Observations of δ Scuti Stars 7 Aql and 8 Aql (a New δ Scuti Variable): The Twelfth STEPHI Campaign in 2003
    We present an analysis of the pulsation behavior of the δ Scuti stars 7 Aql (HD 174532) and 8 Aql (HD 174589), a new variable star, observed in the framework of...
