    A Three-dimensional View of the Remnant of Nova Persei 1901 (GK Per)
    We present a kinematical study of the optical ejecta of GK Per. It is based on proper-motion measurements of 282 knots from ~20 images spanning 25 years...
  • Publication
    A Tidal Extension in the Ursa Minor Dwarf Spheroidal Galaxy
    We report the detection of main-sequence and blue horizontal-branch stars of the Ursa Minor dwarf spheroidal galaxy beyond its tidal radius, indicating the...

    A tidal tale: detection of several stellar streams in the environment of NGC 1052
    The possible existence of two dark-matter-free galaxies (NGC 1052-DF2 and NGC 1052-DF4) in the field of the early-type galaxy NGC 1052 presents a challenge to...
  • Publication
    A tidally tilted sectoral dipole pulsation mode in the eclipsing binary TIC 63328020
    We report the discovery of the third tidally tilted pulsator, TIC 63328020. Observations with the TESS satellite reveal binary eclipses with an orbital period...
  • Publication
    A Time-dependent Semiempirical Model of the Chromospheric Umbral Oscillation
    We present a time-dependent semiempirical model of the chromospheric umbral oscillation in sunspots. This model has been obtained by applying recently developed...
  • Publication
    A time-series VI study of the variable stars of the globular cluster NGC 6397
    We present a new time-series VI CCD photometry of the globular cluster NGC 6397, from which we obtained and analysed the light curves of 35 variables carefully...
  • Publication
    A TiO study of the black hole binary GRO J0422+32 in a very low state
    We present 53 simultaneous photometric (I band) and spectroscopic (6900-9500Å) observations of GRO J0422+32, taken during 1997 December. From these we determine...
  • Publication
    A titanic interstellar medium ejection from a massive starburst galaxy at redshift 1.4
    Feedback-driven winds from star formation or active galactic nuclei might be a relevant channel for the abrupt quenching of star formation in massive galaxies...
  • Publication
    A tool to separate optical/infrared disc and jet emission in X-ray transient outbursts: the colour-magnitude diagrams of XTE J1550-564
    It is now established that thermal disc emission and non-thermal jet emission can both play a role at optical/infrared (OIR) wavelengths in X-ray transients...
