The 2006 Orionid outburst imaged by all-sky CCD cameras from Spain: meteoroid spatial fluxes and orbital elements
Trigo Rodríguez, Josep María; Madiedo Gil, José María
; Llorca, Jordi; Gural, P. S.; Pujols, P.; Tezel, Tunc (Oxford University Press, 2007)
By using high-resolution low-scan-rate all-sky CCD cameras, the SPanish Meteor Network (SPMN) detected an outburst of Orionid meteors associated with comet 1P/Halley on 2006 October 20–21. This detection was made possible ... -
The Ardón L6 ordinary chondrite : a long-hidden Spanish meteorite fall
Trigo Rodríguez, Josep María; Llorca, Jordi; Weyrauch, Mona; Bischoff, Addi; Moyano Cambero, Carles E.; Keil, Klaus; Laubenstein, Matthias; Pack, Andreas; Madiedo Gil, José María; Alonso Azcárate, Jacinto; Riebe, My; Wieler, Rainer; Ott, Uli; Tapia, Mar; Mestres, Narcís (Meteoritical Society, 2014)
We report and describe an L6 ordinary chondrite fall that occurred in Ardón, León province, Spain (longitude 5.5605°W, latitude 42.4364°N) on July 9th, 1931. The 5.5 g single stone was kept hidden for 83 yr by Rosa Gonzólez ... -
Asteroid 2002NY40 as a source of meteorite-dropping bolides
Trigo Rodríguez, Josep María; Lyytinen, E.; Jones, D. C.; Madiedo Gil, José María; Castro Tirado, Alberto J.; Williams, I. P.; Llorca, Jordi; Vítek, Stanislav; Jelinek, M.; Troughton, Blanca; Gálvez, Francisco (Oxford University Press, 2007)
The existence of asteroidal meteoroid streams capable of producing meteorite-dropping bolides has long being invoked, but evidence is scarce. Recent modelling of previously reported associations suggests that the time-scales ... -

Madiedo Gil, José María; Trigo Rodríguez, Josep María; Llorca, Jordi; Tancredi, Gonzalo; Edwards, Wayne N.; Rubin, Alan E.; Weber, Patrick (Wiley-Blackwell Publishing, 2010)
The fall of the Berduc meteorite took place on April 7, 2008, at 01 h 02 min 28 s +/- 1 s UTC. A daylight fireball was witnessed by hundreds of people from Argentina and Uruguay, and also recorded by an infrasound array ... -

A continuous monitoring of the night sky all over Spain will be completed in 2009. This involves the recording over a very large surface area of 500,000 km2, but new CCD and video cameras operated by the Spanish Meteor ... -
Ir reflectante spectra of Antartic carbonaceous chondrites to better characterize the surfaces of asteroids targetted by sample return missions
Trigo Rodríguez, Josep María; Llorca, Jordi; Madiedo Gil, José María; Alonso Azcárate, Jacinto; Rivkin, A. S.; Fornasier, S.; Belskaya, I.; Binzel, R.; Moyano Cambero, Carles E.; Dergham, J.; Cortés, J. (2012)
Undifferentiated carbonaceous asteroids have experienced complex collisional histories, and a significant number are fragments of larger bodies. Meteorites arrived from these asteroids exhibit an amazing reflectance ... -
Is asteroid 2002NY40 a rubble pile gravitationally disrupted
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Bottke, W. F.; Campo Bagatin, Adriano; Tanga, Paolo; Llorca, Jordi; Jones, D. C.; Williams, I. P.; Lyytinen, E. (2008)
The existence of meteoroid streams containing meter-sized meteoroids capable of produc- ing meteorites after atmospheric interaction was pro- posed quite recently [1]. Their existence has important implications because ... -
Large meteoroids on minor cometary streams : recent events detected by the Spanish fireball network
Moreno-Ventas Bravo, Ignacio; Trigo Rodríguez, Josep María; Alonso Azcárate, Jacinto; Izquierdo Gómez, Jaime; Ocaña Gónzalez, Francisco; Castro Tirado, Alberto J.; Llorca, Jordi; Madiedo Gil, José María; Montanyà, J.; Velde, O. van der; Lacruz, J.; Pujols, P.; Cortés, J. (2010)
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 ... -
Low-velocity cometary meteoroid streams encountering the earth: clues on the fragmentation of cometary aggregates and implications for interplanetary dust particles
Since 2005, the SPanish Fireball and Meteor Network (SPMN) is continuously monitor- ing meteor activity by using all-sky CCD and medium- field video cameras up to +3 to +4 meteor limiting magnitude [1,2]. One important ... -
A meteorite-dropping superbolide from the catastrophycally disrupted comet C1919Q2 metcalf : a pathway for meteorites from jupiter family comets
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Williams, I. P.; Castro Tirado, Alberto J.; Llorca, Jordi; Vítek, Stanislav; Jelinek, M. (2009)
It is widely accepted that cometary nu- clei are composed of a mix of volatile ices and meteor- itic materials. In a series of seminal papers F. L. Whipple tried to explain how the irregular internal structure of each ... -
Observations of a very bright fireball and its likely link with comet C/1919 Q2 Metcalf
Trigo Rodríguez, Josep María; Madiedo Gil, José María; Williams, I. P.; Castro Tirado, Alberto J.; Llorca, Jordi; Vítek, Stanislav; Jelinek, M. (Oxford University Press, 2009)
A very bright fireball called B´ejar (SPMN110708), with a maximum brightness of −18, was observed over much of Spain as well as parts of Portugal and France on 2008 July 11 at 21:17:39 UTC. Fortuitously, it flew over ... -
