    A comparison of pendulum models for large-amplitude longitudinal prominence oscillations
    Large-amplitude prominence oscillations offer diagnostic information relevant to understanding the magnetic and plasma structure of solar prominences. Accurate...

    A comprehensive study of the Kepler triples via eclipse timing
    We produce and analyse eclipse time variation (ETV) curves for some 2600 Kepler binaries. We find good to excellent evidence for a third body in 222 systems via...

    A comprehensive study on radial velocity signals using ESPRESSO: Pushing precision to the 10 cm/s level
    Aims. We analyse ESPRESSO data for the stars HD 10700 (τ Ceti), HD 20794 (e Eridani), HD 102365, and HD 304636 acquired via its Guaranteed Time Observations...

    A dearth of planetary transits in the direction of NGC 6940
    We present results of our survey for planetary transits in the field of NGC 6940. We think nearly all of our observed stars are field stars. We have obtained...

    A DECam view of the diffuse dwarf galaxy Crater II: the colour-magnitude diagram
    We present a deep Blanco/DECam colour-magnitude diagram (CMD) for the large but very diffuse Milky Way satellite dwarf galaxy Crater II. The CMD shows only old...

    A dedicated survey of fast-rotating near-Earth asteroids with the Two-meter Twin Telescope: I. Observational strategy and first results
    Context. The rotational properties of small near-Earth asteroids (NEAs) provide crucial insights into their internal structure and collisional history. However...

    A deep learning approach to test the small-scale galaxy morphology and its relationship with star formation activity in hydrodynamical simulations
    Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of...

    A Deep View of the Monoceros Ring in the Anticenter Direction: Clues of Its Extra-galactic Origin
    We present the results of deep imaging obtained at the Canada-France-Hawaii Telescope with MegaCam in the anticenter direction at two different heights above...

    A devil in the detail: parameter cross-talk from the solar cycle and estimation of solar p-mode frequencies
    Frequencies, powers and damping rates of the solar p modes are all observed to vary over the 11-yr solar activity cycle. Here, we show that simultaneous...
