"Los Molinos", R. Gil-Hutton - - Obs. Félix Aguilar, San Juan, Argentina, D. Cogliano - Fac. de Ciencias Astronómicas y Geofísicas de La Plata, Argentina, R. Teixeira - Inst.

Resumen, version Postscript de: Fudamentacion, Informe presentado a III CEA
Postscript version of: Scientific justification
- Chaotic dynamics of comets and
NEAs: computation of Lyapunov times, correspondence with frequency of encounters,
determination of Lyapunov spectra, dynamical taxonomy (Collaborators: V.
Motta - FC; Cl. Froeschle - Obs. Nice)
- Catalogue of Nuclear magnitudes
of Jupiter Family comets: size distribution, fraction of free-sublimating
area, distribution with perihelion distance, comparison with NEAs (Col.
: J.A. Fernández, J. Licandro - FC; H. Rickman - Uppsala
Ast. Obs.)
- Observations of cometary nuclei
at large heliocentric distances (Col.: J. Licandro - FC, Inst. Astrofisico de Canarias; H.
Rickman, M. Lindgren - Uppsala;
R. Gil-Hutton - Obs. Félix Aguilar, San Juan, Argentina)
- Sources for long-lasting Temporary
Satellite Capture like D/Shoemaker-Levy 9 (Col.: A. Sosa - FC)
- Automatic detection of NEAs' trails
in CCD images: application of the Hough transform (Col.: M.
Ruétalo - FC)
- Comparison between methods to compute
Lyapunov Characteristic Coefficients (Col.: F. Roig - Inst.
Ast. y Geofisico, San Pablo, Brazil)
- Search for comets and asteroids
in the vicinity of Jupiter and Saturn (Uppsala-ESO Survey for Asteroids
and Comets - UESAC) (Col.: A. Sosa - FC,C.-I.
Lagerkvist,
O. Hernius, M. Lindgren - Uppsala)
- Observations of mm lines of CO in Schwachmann-Wachmann 1 with SEST, source of the CO (Col.: H. Rickman & M. Gunnarson - Uppsala; M. Festou - Obs. Toulose, France; A. Winnberg - Onsala Rymobservatorium, Sweden)
- Integral field spectroscopy of the cometary comae, observations of Hale-Bopp (Col.: S. Fernandez & R. Garcia - Obs. Cordoba, Argentina)
- Thermochemistry of Cometary Nuclei:
models for homogeneus nuclei with water ice, CO and dust; phase transition,
sublimation and recondesation, activity at large heliocentric distances
(Col.: H. Rickman - Uppsala; M. Greenberg - Leiden Astrophysical
Laboratory)
