  • Uranus & Neptune topocentric positions

    Catalogs of 145 astrometric positions of Uranus and 4 its moons U1-U4 and 62 positions of Neptune and Triton have been compiled with Tycho-2 as a reference frame from...
  • Stellar parameters of KOI stars

    The abundance of heavy elements (metallicity) in the photospheres of stars similar to the Sun provides a "fossil" record of the chemical composition of the initial...
  • Radial velocities of Kepler-34b & Kepler-35b

    Most Sun-like stars in the Galaxy reside in gravitationally bound pairs of stars (binaries). Although long anticipated the existence of a 'circumbinary planet' orbiting such a...
  • 398-710nm Sun spectral atlases

    In this work, we present digital and graphical atlases of spectra of both the solar disk-center and of the limb near the Solar poles using data taken at the UTS-IAP & RIAAM...
  • NEA (23187) 2000 PN9 lightcurves

    We present a physical model and spin-state analysis of the potential ly hazardous asteroid (23187) 2000 PN9. As part of a long-term campaign to make direct detections of the...
  • Comet 162P/Siding Spring photometry

    Comet 162P/Siding Spring is a large Jupiter-family comet with extensive archival lightcurve data. We report new r-band nucleus lightcurves for this comet, acquired in 2018, 2021...
  • NEA (2102) Tantalus light curves

    Between 2010 and 2017 we have collected new optical and radar observations of the potentially hazardous asteroid (2102) Tantalus from the ESO NTT and Danish telescopes at the La...
  • Contact-binary (68346) 2001 KZ66 light curves

    The YORP effect is a small thermal-radiation torque experienced by small asteroids, and is considered to be crucial in their physical and dynamical evolution. It is important to...
  • A comparison of centering in ISS astrometry

    In the caviar software package, a standard tool for astrometry of images from the Cassini imaging science subsystem (ISS), Gaussian fitting is used to measure the centre of...
  • Deuterated methanol in comet 67P/C-G

    Deuterated methanol is one of the most robust windows astrochemists have on the individual chemical reactions forming deuterium-bearing molecules and the physicochemical history...
  • V-types Main Set and HED meteorites catalogues

    We aim to determine the distribution of basaltic asteroids (classified as V-types) based on the spectrophotometric data reported in the MOVIS-C catalogue. A total of 782...
  • Multiple absorption features in debris discs

    Debris discs are second-generation dusty discs thought to be devoid of gas. However, this idea has been challenged in the last years by gas detections in some systems. We...
  • WASP-80b wavelength-binned light curves

    We have performed ground-based transmission spectroscopy of the hot Jupiter orbiting the cool dwarf WASP-80 using the ACAM instrument on the William Herschel Telescope (WHT) as...
  • Large perihelion dist. Oort spike comets

    The complete sample of large-perihelion nearly-parabolic comets discovered during the period 1901-2010 is studied, starting with their orbit determination. Next, an orbital...
  • Kepler-410Ab transit timing variations

    For the determination of the individual times of transit we used short- cadence (sampled every 58.8 seconds) de-trended data (PDCSAP_FLUX) from quarters Q1 to Q17, provided by...
  • HAT-P-18b wavelength binned light curves

    We have performed ground-based transmission spectroscopy of the hot Jupiter HAT-P-18b using the ACAM instrument on the William Herschel Telescope (WHT). Differential...
  • Light curves of WASP-52

    We report 13 high-precision light curves of eight transits of the exoplanet WASP-52 b, obtained by using four medium-class telescopes, through different filters, and adopting...
  • Exoplanet candidates in Praesepe (M 44)

    In this work we keep pushing K2 data to a high photometric precision, close to that of the Kepler main mission, using a PSF-based, neighbour-subtraction technique, which also...
  • Robotic view of 67P perihelion

    Around the time of its perihelion passage, the observability of 67P/Churyumov-Gerasimenko from Earth was limited to very short windows each morning from any given site, due to...
  • Multi-band light curve of WASP-36

    We present broad-band photometry of five transits in the planetary system WASP-36, totaling 17 high-precision light curves. Four of the transits were simultaneously observed in...
