Simulating asteroid impacts and meteor events by high-power lasers: from the laboratory to spaceborne missions
Meteor plasmas and impact events are complex, dynamic natural phenomena. Simulating
these processes in the laboratory is, however, a challenge. The technique of laser induced …

Artificial meteors observed in mid-infrared range
S Rommeluère, J Vaubaillon, S Loehle… - Icarus, 2024 - Elsevier
Meteors are most often observed from the ground in the visible, most often at a distance of at
least 80–100 km between the phenomenon and the observer. Such constraints lead to …
