Geminids are initially cracked by atmospheric thermal stress
Tomáš Henych, Jiří Borovička, David Čapek +4
Geminids have the highest bulk density of all major meteor showers and their mechanical strength appears to depend on their mass. They are also the most active annual shower, enabl…

Spectroscopic analysis of hydrogen and silicon in bright fireballs: New insights into meteoroid composition
V. Vojáček, J. Borovička, P. Spurný
We present a study of the high-temperature spectral component in meteor fireballs, with a particular focus on neutral hydrogen at 656.28 nm and ionised silicon doublet at 634.71 nm…
