Experimental evidence for physical alteration of fine regolith on near-Sun asteroids
Jooyeon Geem, Mikael Granvik, Georgios Tsirvoulis +5
The surfaces of airless bodies evolve through processes such as (micro)meteoroid impacts and thermal fatigue, which modify physical properties such as grain size, porosity, and min…
SHINeS: Space and High-Irradiance Near-Sun Simulator
Georgios Tsirvoulis, Mikael Granvik, Athanasia Toliou
We present SHINeS, a space simulator which can be used to replicate the thermal environment in the immediate neighborhood of the Sun down to a heliocentric distance r~0.06 au. The…
Minimum perihelion distances and associated dwell times for near-Earth asteroids
Athanasia Toliou, Mikael Granvik, Georgios Tsirvoulis
The observed near-Earth asteroid population contains very few objects with small perihelion distances, say, q<=0.2 au. NEAs that currently have orbits with larger q might be hiding…
Secular resonance sweeping and orbital excitation in decaying disks
A. Toliou, K. Tsiganis, G. Tsirvoulis
We revisit the problem of secular resonance sweeping during the dissipation of a protoplanetary disk and its possible role in exciting the orbits of primordial asteroids, in the li…
Discovery of a young subfamily of the (221)~Eos asteroid family
Georgios Tsirvoulis
In this work we report the discovery of a young cluster of asteroids that originated by the breakup of an asteroid member of the (221)Eos family. By applying the Hierarchical clust…
Reconstructing the size distribution of the primordial Main Belt
Georgios Tsirvoulis, Alessandro Morbidelli, Marco Delbo +1
In this work we aim to constrain the slope of the size distribution of main-belt asteroids, at their primordial state. To do so we turn out attention to the part of the main astero…
A dark asteroid family in the Phocaea region
Bojan Novakovic, Georgios Tsirvoulis, Mikael Granvik +1
We report the discovery of a new asteroid family among the dark asteroids residing in the Phocaea region the Tamara family. We make use of available physical data to separate aster…
Secular resonances with Ceres and Vesta
Georgios Tsirvoulis, Bojan Novakovic
In this work we explore dynamical perturbations induced by the massive asteroids Ceres and Vesta on main-belt asteroids through secular resonances. First we determine the location…
Secular evolution of asteroid families: the role of Ceres
Bojan Novakovic, Georgios Tsirvoulis, Stefano Maro +2
We consider the role of the dwarf planet Ceres on the secular dynamics of the asteroid main belt. Specifically, we examine the post impact evolution of asteroid families due to the…
Asteroid secular dynamics: Ceres' fingerprint identified
Bojan Novaković, Clara Maurel, Georgios Tsirvoulis +1
Here we report on the significant role of a so far overlooked dynamical aspect, namely a secular resonance between the dwarf planet Ceres and other asteroids. We demonstrate that t…
