    What future awaits the Sun?
    The Sun and other similar (solar-like) stars have an internal magnetic field that can emerge on the surface, forming features such as dark spots, which drive...

    What ignites on the neutron star of 4U 0614+091?
    The low-mass X-ray binary 4U 0614+091 is a source of sporadic thermonuclear (type I) X-ray bursts. We find bursts with a wide variety of characteristics in...

    What is the Milky Way outer halo made of?. High resolution spectroscopy of distant red giants
    In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

    What Is the Redshift of the Gamma-ray BL Lac Source S4 0954+65?
    High signal-to-noise ratio spectroscopic observations of the BL Lac object S4 0954+65 at the alleged redshift z = 0.367 are presented. This source was detected...

    When binaries keep track of recent nucleosynthesis. The Zr-Nb pair in extrinsic stars as an s-process diagnostic
    Context. Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During this phase they were polluted...

    When Is a Bulge Not a Bulge? Inner Disks Masquerading as Bulges in NGC 2787 and NGC 3945
    We present a detailed morphological, photometric, and kinematic analysis of two barred S0 galaxies with large, luminous inner disks inside their bars. We show...

    When nature tries to trick us. An eclipsing eccentric close binary superposed on the central star of the planetary nebula M 3-2
    Bipolar planetary nebulae (PNe) are thought to result from binary star interactions and, indeed, tens of binary central stars of PNe have been found, in...

    When the disc's away, the stars will play: dynamical masses in the nova-like variable KR Aur with a pinch of accretion
    We obtained time-resolved optical photometry and spectroscopy of the nova-like variable KR Aurigae in the low state. The spectrum reveals a DAB white dwarf (WD)...

    When the horseshoe fits: Characterizing 2023 FY<SUB>3</SUB> with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
    Context. The Arjuna asteroid belt is loosely defined as a diverse group of small asteroids that follow dynamically cold, Earth-like orbits. Most of them are not...
