    Mass-loss of globular cluster red giants - A semi-empirical estimation
    Limits to the total mass-loss in red giants in globular clusters are calculated on the basis of Sweigart and Gross (1976) Horizontal Branch models by means of...

    Mass-metallicity relation explored with CALIFA. I. Is there a dependence on the star-formation rate?
    We studied the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral field...

    Mass-metallicity relation of dwarf galaxies and its dependency on time: clues from resolved systems and comparison with massive galaxies
    Aims: We present a new approach to study the mass-metallicity relation and its dependency on time. Methods: We used the star formation history (SFH) derived...

    Mass-to-light ratios from the fundamental plane of spiral galaxy discs
    The best-fitting two-dimensional plane within the three-dimensional space of spiral galaxy disc observables (rotational velocity vrot, central disc surface...

    Masses and ages for metal-poor stars. A pilot programme combining asteroseismology and high-resolution spectroscopic follow-up of RAVE halo stars
    Context. Very metal-poor halo stars are the best candidates for being among the oldest objects in our Galaxy. Samples of halo stars with age determination and...

    Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley
    We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf (d = 22 pc, M ⋆ = 0.39 M ⊙, R ⋆ = 0.38 R ⊙), which hosts three transiting...

    Masses, revised radii, and a third planet candidate in the 'Inverted' planetary system around TOI-1266
    Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number...

    Massive Clumps in Local Galaxies: Comparisons with High-redshift Clumps
    Local UV-bright galaxies in the Kiso survey include clumpy systems with kiloparsec-size star complexes that resemble clumpy young galaxies in surveys at high...

    Massive Galaxies in COSMOS: Evolution of Black Hole Versus Bulge Mass but not Versus Total Stellar Mass Over the Last 9 Gyr?
    We constrain the ratio of black hole (BH) mass to total stellar mass of type-1 active galactic nuclei (AGNs) in the COSMOS survey at 1 z 2. For 10 AGNs at...
