Gustavo Madeira
Content / Work
Gustavo Madeira is Ph.D. in Physics and Astronomy, currently holding the position of Postdoctoral Researcher at the Institut de Physique du Globe in Paris. He works with the physics of planetary rings, circumplanetary disks, satellite formation, and the dynamic evolution of Solar System bodies. His specialty is the analytical development of orbital dynamics and numerical simulations. His main research topics are:- Satellite formation: accretion in circumplanetary disks, accretion in debris disks, pebble accretion, Galilean satellites, tidal evolution.
- Giant impacts: origin of Phobos and Deimos, origin of Moon.
- Minor impacts: dust production by impacts.
- Ring dynamics: stability and formation of planetary rings and arcs.
- Disturbing effects on minor bodies: solar radiation force, plasma drag, Lorentz forces, tidal effect, and Yarkovsky effects.

Animations:
- Figure 4/Figure 6: Evolution of disk surface density (solid blue line, left scale) and satellite mass (black dots, right scale) as a function of distance to Mars (semimajor axis in Mars radius). Simulation time is given at the top, and vertical dashed lines show the location of rigid Roche Limit (1.74 Mars radius) and fluid Roche Limit (3.14 Mars radius). The simulation corresponds to a case with full destruction of Phobos, with initial disk mass being 1.1e4 masses of Phobos, particle size of 10 meters, and friction angle of 40 deg.
- Figure 11: Evolution of disk surface density (solid blue line, left scale) and satellite mass (black dots, right scale) as a function of distance to Mars (semimajor axis in Mars radius). Simulation time is given at the top, and vertical dashed lines show the location of rigid Roche Limit (1.74 Mars radius) and fluid Roche Limit (3.14 Mars radius). The simulation corresponds to a case with full destruction of Phobos and including Yarkovsky effects, with initial disk mass being 0.9e4 masses of Phobos, particle size of 0.1 meters, and friction angle of 25 deg.
- Figure 13: Evolution of disk surface density (solid blue line, left scale) and satellite mass (black dots, right scale) as a function of distance to Mars (semimajor axis in Mars radius). Simulation time is given at the top, and vertical dashed lines show the location of rigid Roche Limit (1.74 Mars radius) and fluid Roche Limit (3.14 Mars radius). The simulation corresponds to a case with tidal downsizing, with initial disk mass being 1.1e4 masses of Phobos, particle size of 10 meters, and friction angle of 40 deg.
