Photometric stellar variation due to extra-solar comets
A. Lecavelier des Etangs, A. Vidal-Madjar, R. Ferlet
We performed numerical simulations of stellar occultations by extra-solar cometary tails. We find that extra-solar comets can be detected by the apparent photometric variations of…

Dust distribution in radiation pressure outflow. Application to the BD+31d643 disk
A. Lecavelier des Etangs, A. Vidal-Madjar, R. Ferlet
The radial distribution of dust has been calculated in outflows driven by radiation pressure in which the gas drag is taken into account. It is shown that the dust distribution in…
