Footprints of a possible Ceres asteroid paleo-family
(2016-02-22)
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 280 km in diameter on the Ceres surface, that could ...
Mascon gravitation model using a shaped polyhedral source
(2015-01-01)
In the last two decades, new computational tools have been developed in order to aid space missions to orbit around irregular small bodies. One of the techniques consists in rebuilding their shape in tetrahedral polyhedron. ...
On the erigone family and the z2 secular resonance
(2016-01-01)
The Erigone family is a C-type group in the inner main belt. Its age has been estimated by several researchers to be less then 300 Myr, so it is a relatively young cluster. Yarko-YORP Monte Carlo methods to study the ...
Dynamics in the vicinity of (101955) Bennu: Solar radiation pressure effects in equatorial orbits
(2017-09-21)
Here, we study the dynamical effects of the solar radiation pressure (SRP) on a spacecraftthat will survey the near-Earth rotating asteroid (101955) Bennu when the projected shadowis accounted for. The spacecraft's motion ...
The Hoffmeister asteroid family
(2017-01-01)
The Hoffmeister family is a C-type group located in the central main belt. Dynamically, it is important because of its interaction with the ν1C nodal secular resonance with Ceres, which significantly increases the dispersion ...
Resonant capture and tidal evolution in circumbinary systems: Testing the case of Kepler-38
(Wiley Blackwell Publishing, Inc, 2018-07)
Circumbinary planets are thought to form far from the central binary and migrate inwards by interactions with the circumbinary disc, ultimately stopping near their present location either by a planetary trap near the disc ...
