Dynamical evolution and end states of active and inactive Centaurs
Julio A. Fernández, Michel Helal, Tabaré Gallardo
We numerically study the dynamical evolution of observed samples of active and inactive Centaurs and clones that reach the Jupiter-Saturn region. Our aim is to compare the evolutio…
Physical and dynamical properties of the anomalous comet 249P/LINEAR
Julio A. Fernández, Javier Licandro, Fernando Moreno +4
Images and low-resolution spectra of the near-Earth Jupiter family comet (JFC) 249P/LINEAR in the visible range obtained with the instrument OSIRIS in the 10.4m Gran Telescopio Can…
The end states of long-period comets and the origin of Halley-type comets
Julio A. Fernández, Tabaré Gallardo, Juan D. Young
We analyze a sample of 73 old long-period comets (LPCs) (orbital periods yr) with perihelion distances au, discovered in the period 1850-2014. We cloned…
Assessing the physical nature of near-Earth asteroids through their dynamical histories
Julio A. Fernández, Andrea Sosa, Tabaré Gallardo +1
We analyze a sample of 139 near-Earth asteroids (NEAs), defined as those that reach perihelion distances au, and that also fulfill the conditions of approaching or crossi…
Magnitude and size distribution of long-period comets in Earth-crossing or approaching orbits
Julio A. Fernández, Andrea Sosa
We analyse the population of near-Earth Long-Period Comets (LPCs) (perihelion distances q < 1.3 AU and orbital periods P > 10^3 yr). We have considered the sample of LPCs discovere…
