Galilean satellites & Jupiter positions
For observational period of 2009-2011 we have obtained 140 positions of Galilean satellites and 42 calculated positions of Jupiter in the system of UCAC4 catalogue (ICRS,... -
CCD observations of saturnian satellites
The astrometric positions of seven saturnian satellites are presented. Positions were derived from more then 5000 CCD frames taken with 26-inch Zeiss refractor at Pulkovo from... -
29P/Schwassmann-Wachmann 1 light curves
Comets offer valuable insights into the early Solar System's conditions and processes. Stellar occultations enables detailed study of cometary nuclei typically hidden by their... -
5 Saturnian satellites Cassini ISS Astrometry
The Imaging Science Subsystem (ISS) mounted on the Cassini spacecraft has taken a lot of images, which provides an important source of high-precision astrometry of some planets... -
Major uranian sat. astrometric performance
During ground-based observations of satellites near a bright planet, the satellite images are often affected by the planet's halo, introducing significant uncertainty in their... -
Astrometry of Cassini ISS Images of Phoebe
Phoebe is the only major satellite of Saturn with a retrograde orbit. The Cassini Imaging Science Subsystem (ISS) took a lot of Phoebe images between 2004 and 2017, but only a... -
Astrometry of the 5 largest Uranian sat.
We present the astrometry of the five largest satellites of Uranus from observations spread over almost three decades with photographic plates and CCDs (mainly), taken at the... -
1847 WISE-observed asteroids thermal properties
We present new thermophysical model (TPM) fits of 1847 asteroids, deriving thermal inertia, diameter, and Bond and visible geometric albedo. We use thermal flux measurements... -
The Raman spectrum of the atmosphere at 23km
Ground-based optical astronomical observations supported by or in the vicinity of laser guide-star systems can be contaminated by Raman-scattered laser photons. Anticipating,... -
Topocentric positions of Saturn's moons
A catalog of 1399 astrometric positions of Saturn's moons S2-S9 has been compiled with Tycho-2 as a reference frame from photographic observations obtained at the Main... -
S-type asteroids reflect. spectra param.
The search for asteroidal parent bodies of chondrites through various techniques is an ongoing endeavor. A link between ordinary chondrites (OCs) and S-type asteroids has... -
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... -
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... -
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... -
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... -
Possible Ceres asteroid paleo-family
Ceres is the largest and most massive body in the asteroid main belt. Observational data from the Dawn spacecraft reveal the presence of at least two impact craters about 280km... -
Stellar encounters with long-period comets
The Solar system's Oort cloud can be perturbed by the Galactic tide and by individual passing stars. These perturbations can inject Oort cloud objects into the inner parts of... -
Precise CCD positions of Phoebe in 2011-2014
346 new CCD observations during the years 2011-2014 have been reduced to derive the precise positions of Phoebe, the ninth satellite of Saturn. The observations were made by the... -
SUNS and DEBRIS surveys target selection
Debris discs - analogous to the asteroid and Kuiper-Edgeworth belts in the Solar system - have so far mostly been identified and studied in thermal emission shortward of 100um.... -
Positions of 5 Uranian satellites from Yunnan obs.
A total of 10,339 positions of the five major Uranian satellites (Ariel, Umbriel, Titania, Oberon and Miranda) were collected at the Yunnan Observatories from 2013 to 2020 with...
