    Bulgeless Evolution And the Rise of Discs (BEARD): II. The role of mergers in shaping the Milky Way analogues in TNG50
    We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic...

    Bulges of disk galaxies at intermediate redshifts. I. Samples with and without bulges in the Groth Strip survey
    Context: Analysis of bulges to redshifts of up to z ˜ 1 have provided ambiguous results as to whether bulges as a class are old structures akin to elliptical...

    Bulges of disk galaxies at intermediate redshifts. II. Nuclear, disk, and global colors in the Groth Strip
    Context: The chronology of bulge and disk formation is a major unsolved issue in galaxy formation, which impacts on our global understanding of the Hubble...

    Burst-properties as a function of mass accretion rate in GX 3+1
    GX 3+1 is a low-mass X-ray binary that is persistently bright since its discovery in 1964. It was found to be an X-ray burster twenty years ago proving that the...

    Bursts, eclipses, dips and a refined position for the luminous low-mass X-ray binary in the globular cluster Terzan 6
    GRS 1747-312 is a bright transient X-ray source in the globular cluster Terzan 6 with quasi-periodic outbursts approximately every 4.5 months. We carried out 2...

    C and N abundances of main sequence and subgiant branch stars in NGC 1851
    We present the first chemical analysis of stars on the double subgiant branch (SGB) of the globular cluster NGC 1851. We obtained 48 Magellan IMACS spectra of...

    C, S, Zn and Cu abundances in planet-harbouring stars
    We present a detailed and uniform study of C, S, Zn and Cu abundances in a large set of planet host stars, as well as in a homogeneous comparison sample of...

    C/O vs. Mg/Si ratios in solar type stars: The HARPS sample
    Context. Aims: We aim to present a detailed study of the magnesium-to-silicon and carbon-to-oxygen ratios (Mg/Si and C/O) and their importance in determining...

    Ca II 8542 Å brightenings induced by a solar microflare
    Aims: We study small-scale brightenings in Ca II 8542 Å line-core images to determine their nature and effect on localized heating and mass transfer in active...
