Large meteoroids on minor cometary streams : recent events detected by the Spanish fireball network
F. L. Whipple first modeled the forma-tion of meteoroid streams from the continuous subli-mation of the ice-rich regions in cometary nuclei [1,2,3]. Particles lifted off from ice-rich regions by the sublimated gas drag ...
The 2011 October Draconids outburst – I. Orbital elements, meteoroid fluxes and 21P/Giacobini–Zinner delivered mass to Earth
(Oxford University Press, 2013)
On 2011 October 8, the Earth crossed the dust trails left by comet 21P/Giacobini–Zinner during its 19th and 20th century perihelion approaches with the comet being close to perihelion. The geometric circumstances of that ...
The 2011 Giacobinid outburst : meteoroid flux determination and orbital data by using video imagery from the Spanish fireball network
On October 8th, 2011 the Earth encountered the dust trails left by comet 21P/Giacobini- Zinner during its XIX and XX century perihelion approaches. The encounter was forecasted in great detail [1, 2, 3]. Geometic ...
Analisys of a superbolide observed over the Iberian Peninsula on July 21, 2012
A superbolide was observed on July 21, 2012 over the center and south of Spain. The event was recorded in the framework of our continuous fireball monitoring and spectroscopic campaigns. Besides, because of optimal ...
Orbit, emission spectrum, and photometric analysis of two flickering sporadic fireballs
(EDP Sciences, 2013)
We present the observations of two fireballs that exhibit fast and quasi-periodic brightness variations along their atmospheric path. This phenomenon, which is known as “flickering”, is associated to the entry of spinning ...
