    Doppler tomography of transiting exoplanets: a prograde, low-inclined orbit for the hot Jupiter CoRoT-11b
    We report the detection of the Doppler shadow of the transiting hot Jupiter CoRoT-11b. Our analysis is based on line-profile tomography of time-series, Keck...
  • Publication
    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...

    Doppler-velocity Drifts Detected in a Solar Prominence
    We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated...

    Double Bars, Inner Disks, and Nuclear Rings in Early-Type Disk Galaxies
    We present results from a survey of an unbiased sample of 38 early-type (S0-Sa), low-inclination, optically barred galaxies in the field, using images both from...
  • Publication
    Double-barred galaxies. I. A catalog of barred galaxies with stellar secondary bars and inner disks
    I present a catalog of 67 barred galaxies which contain distinct, elliptical stellar structures inside their bars. Fifty of these are double-barred galaxies: a...

    Double-lined Spectroscopic Binaries in the APOGEE DR16 and DR17 Data
    APOGEE spectra offer ≲1 km s -1 precision in the measurement of stellar radial velocities. This holds even when multiple stars are captured in the same spectrum...

    Double-peak structure in the cyclic optical outbursts of blazar OJ 287.
    An international monitoring project, called OJ-94, was set up with the aim of monitoring blazar OJ 287 during the predicted optical outburst (in fall 1994...

    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...

    Downflowing umbral flashes as evidence of standing waves in sunspot umbrae
    Context. Umbral flashes are sudden brightenings commonly visible in the core of some chromospheric lines. Theoretical and numerical modeling suggests that they...
