A 13 kg meteoroid from comet 21P/Giacobini-Zinner recorded as a bolide during the 2011 draconid outburst
Madiedo Gil, José María
; Trigo Rodríguez, Josep María; Konovalova, N.; Castro Tirado, Alberto J. (2012)
The parent body of the Draconid meteoroid stream is the short period comet 21P/Giacobini-Zinner. This cometary debris gives rise to an annual display of meteors from about October 6 to October 10, with a maximum activity ... -
The 2011 October Draconids outburst – II. Meteoroid chemical abundances from fireball spectroscopy
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Konovalova, N.; Williams, I. P.; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Cabrera Caño, Jesús (Oxford University Press, 2013)
On October 8, 2011 the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and ... -
Analysis of large meteoroids produced by comet 7P/Pons-Winnecke
Rodríguez Ramírez, Antonio; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Konovalova, N. (2012)
Dust ejecta of comet 7P/Pons- Winnecke produces the June Bootid meteoroid stream [1]. This gives rise to an annual display of meteors from about June 22 to July 2, with a maximum activity around June 28. A continuous ... -
Meteorite-dropping bodies from cometary meteoroid streams and their physical properties
Until recently it was considered that the sources of meteorite-dropping bodies are asteroidal fragments mostly delivered by main belt resonances crossing the Earth’s orbit. Such source may include a considerable fraction ... -
Near earth object 2012XJ112 as a source of bright bolides of achondritic nature
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Williams, I. P.; Konovalova, N.; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Pastor, S.; Reyes, J. A. de los; Cabrera Caño, Jesús (Oxford University Press, 2014)
We analyze the likely link between the recently discovered Near Earth Object 2012XJ112 and a bright fireball observed over the south of Spain on December 27, 2012. The bolide, with an absolute magnitude of -9±1, was ... -
Orbit, emission spectrum, and photometric analysis of two flickering sporadic fireballs
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Konovalova, N.; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Alonso Azcárate, Jacinto; Lacruz, J.; Cabrera Caño, Jesús (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 ... -
The physical properties of the june bootids and de July 23, 2008 superbolide
Many cometary meteoroid streams crossing the Earth were formed from the continuous sublimation of the ice-rich regions in cometary nuclei [1,2,3]. Another mechanism of producing cometary meteoroid streams is the ...
