Trigo Rodríguez, Josep María; Madiedo Gil, José María
; Williams, I. P.; Cortés, J.; Dergham, J.; Pujols, P.; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Alonso Azcárate, Jacinto; Zamorano, J.; Izquierdo Gómez, Jaime; Ocaña Gónzalez, Francisco; Sánchez de Miguel, A.; Tapia, Mar; Martín Torres, J.; Lacruz, J.; Rodríguez, Diego; Pruneda, Francesc; Oliva, Armand; Pastor Erades, Juan (2012)
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 ... -
The 2011 October Draconids outburst – I. Orbital elements, meteoroid fluxes and 21P/Giacobini–Zinner delivered mass to Earth
Trigo Rodríguez, Josep María; Madiedo Gil, José María; Williams, I. P.; Dergham, J.; Cortés, J.; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Zamorano, J.; Ocaña Gónzalez, Francisco; Izquierdo Gómez, Jaime; Sánchez de Miguel, A.; Alonso Azcárate, Jacinto; Rodríguez, Diego; Tapia, Mar; Pujols, P.; Lacruz, J.; Pruneda, Francesc; Oliva, Armand; Pastor Erades, Juan; Marín, Antonio Francisco (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 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 ... -
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 ... -
The impact of neos and their fragments recorded from the ground : ongoing research lines of the spanish fireball network
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Llorca, Jordi; Williams, I. P.; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Alonso Azcárate, Jacinto; Zamorano, J.; Lanchares, Víctor; Docobo, José A.; Fabregat Llueca, Juan (2009)
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 ... -
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 ... -
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 ... -
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 ... -
The Northern χ-Orionid meteoroid stream and possible association with the potentially hazardous asteroid 2008XM1
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Williams, I. P.; Ortiz Moreno, José Luis; Cabrera Caño, Jesús (Oxford University Press, 2013)
We present new orbital data and dynamic results pointing towards the origin of the Northern χ-Orionid meteoroid stream, which is a part of the Taurid meteoroid complex. A new software package was developed to establish ... -
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 ... -
The outburst of the κ Cygnids in 2007: clues about the catastrophic break up of a comet to produce an Earth-crossing meteoroid stream
Trigo Rodríguez, Josep María; Madiedo Gil, José María; Williams, I. P.; Castro Tirado, Alberto J. (Oxford University Press, 2009)
Using high-resolution, low-scan-rate, all-sky CCD cameras and high-level CCD video cameras, the SPanish Meteor and fireball Network (SPMN) recorded the 2007 κ Cygnid fireball outburst from several observing stations. ...
