Comet 153P/Ikeya-Zhang emission lines catalog
A program of high resolution spectroscopy of comets is being conducted at TNG (Canary Islands) using the echelle spectrograph SARG. The aim of the program is to catalogue... -
Photometric observations of comets
We present CCD VRc photometry of 3 distant active comets visible in July, 2000. Time-series data cover 16 hours. Data were obtained with the 1.23m telescope of the... -
Comet C/1995 O1 (Hale-Bopp) emission lines
High-resolution and high signal-to-noise ratio spectra of Comet C/1995 O1 (Hale-Bopp), which provided continuous wavelength coverage from 5500{AA} to 8500{AA} and partial... -
Database of the orbital elements of comets
comets.dat is an ASCII file of cometary orbital elements prepared at the "Institut de Mecanique Celeste et de Calcul des Ephemerides" (related to the Bureau des Longitudes,... -
VOEvent meteor shower service
The ephemeris were produced by simulating the ejection of meteoroids from the sunlit hemisphere of cometary nuclei, typically from 0 to 3 au, followed by the propagation of... -
Properties of asteroids in comet-like orbits
We investigated the population of asteroids in comet-like orbits using available asteroid size and albedo catalogs of data taken with the Infrared Astronomical Satellite, AKARI,... -
Nuclear magnitudes of Jupiter family comets
A catalog of a sample of 105 Jupiter family (JF) comets (defined as those with Tisserand constants T>2 and orbital periods P<20yr) is presented with our ``best estimates''... -
Cometary dust collected by MIDAS on-board Rosetta
The MIDAS (Micro-Imaging Dust Analysis System) atomic force microscope on board the Rosetta comet orbiter investigated and measured the 3D topography of a few hundred nm to tens... -
Cometary dust collected by MIDAS on-board Rosetta
The Micro-Imaging Dust Analysis System (MIDAS) atomic force microscope (AFM) on board the Rosetta comet orbiter has been dedicated to the collection and 3D topographical... -
122 long-period comets non-gravitational param.
The original 1/a-distribution is the only observational basis for the origin of long-period comets (LPCs) and the dynamical properties of the Oort Cloud. Although they are very... -
TESS light curve of beta Pictoris
We search for signs of falling evaporating bodies (FEBs, also known as exocomets) in photometric time series obtained for {beta} Pictoris after fitting and removing its {delta}... -
Separation and confirmation of showers
Using IAU MDC photographic, IAU MDC CAMS video, SonotaCo video, and EDMOND video databases, we aim to separate all provable annual meteor showers from each of these databases.... -
Cometary activity of comet C/2006 S3 (LONEOS)
The study of small bodies that have a cometary activity at a large heliocentric distance (larger than 5AU) is important for a better understanding of the physical properties of... -
New catalogue of one-apparition comets
The orbits of one-apparition comets discovered in the early part of the last century have formerly been determined with very different numerical methods and assumptions on the... -
18-cm OH lines in comets
Since the apparition of comet Kohoutek 1973 XII, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nancay radio telescope.... -
