Instantaneous thermally-driven erosion can explain dearth of dark near-Sun asteroids
Georgios Tsirvoulis, Mikael Granvik, Leonard Schirner +3
Recent models of the near-Earth asteroid population show that asteroids must be super-catastrophically destroyed when they evolve to orbits with perihelion passages well inside of…
Resonant mechanisms that produce near-Sun asteroids
Athanasia Toliou, Mikael Granvik
All near-Earth asteroids (NEAs) that reach sufficiently small perihelion distances will undergo a so-called super-catastrophic disruption. The mechanisms causing such disruptions a…
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…
Dynamical Evolution and Thermal History of Asteroids (3200) Phaethon and (155140) 2005 UD
Eric M. MacLennan, Athanasia Toliou, Mikael Granvik
The near-Earth objects (NEOs) (3200) Phaethon and (155140) 2005 UD are thought to share a common origin, with the former exhibiting dust activity at perihelion that is thought to d…
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…
