    Do galaxies form a spectroscopic sequence?
    We identify a spectroscopic sequence of galaxies, analogous to the Hubble sequence of morphological types, based on the Automatic Spectroscopic K-means-based...

    Doppler and modulation tomography of XTEJ1118+480 in quiescence
    We present Doppler and modulation tomography of the X-ray nova XTEJ1118+480 with data obtained during quiescence using the 10-m Keck II telescope. The hotspot...

    Doppler tomography of the X-ray transient J0422+32 during the 1993 December mini-outburst
    Intermediate-resolution optical spectra of the X-ray transient J0422+32, obtained during the 1993 December mini-outburst, show a strong modulation in radial...

    Doppler tomography of XTE J1118+480 revealing chromospheric emission from the secondary star
    Doppler tomography of emission lines in low-mass X-ray binaries allows us to investigate the structure and variability of the accretion discs as well as...

    Doubling of minute-long quasi-periodic pulsations from super-flares on a low-mass star
    Using the ULTRASPEC instrument mounted on the 2.4-m Thai National Telescope, we observed two large flares, each with a total energy close to 10 34 erg with sub...

    Dust beyond the torus: revealing the mid-infrared heart of local Seyfert ESO 428-G14 with JWST/MIRI
    Polar dust has been discovered in a number of local active galactic nuclei (AGN), with radiation-driven torus models predicting a wind to be its main driver...

    Dust environment of active asteroids P/2019 A4 (PANSTARRS) and P/2021 A5 (PANSTARRS)
    We report on the characterization of the dust activity and dynamical evolution of two faint active asteroids, P/2019 A4, and P/2021 A5, observed with the 10.4 m...

    Dust from evolved stars: a pilot analysis of the AGB to PN transition
    We present a novel approach to address dust production by low- and intermediate-mass stars. We study the asymptotic giant branch (AGB) phase, during which the...

    Dust in the central parsecs of unobscured AGN: more challenges to the torus
    A parsec-scale dusty torus is thought to be the cause of active galactic nuclei (AGN) dichotomy in the 1/2 types, narrow/broad emission lines. In a previous...
