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 ... -
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 ... -
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 ... -
The Puerto Lápice eucrite. Free sample delivery from vesta : trajectory, orbital solutions, and shock history from cathodoluminiscence
Trigo Rodríguez, Josep María; Llorca, Jordi; Madiedo Gil, José María; Jambon, A.; Chennaoui Aoudjehane, H. (2009)
A daylight fireball was witnessed all over Spain in the afternoon of May 10, 2007. Several pictures of the fireball’s train taken from different locations in Spain, and eyewitnesses reports allowed the determination of ... -
Robotic systems for meteor observing and lunar impact flashes detection in Spain
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Ortiz Moreno, José Luis; Morales, Nicolás (2009)
Since November 2008, a new robotic observatory is being setup by the University of Huelva within the environment of the Doñana Natural Park, in the south- west of Spain. Most of the systems in this astronomical observatory ... -
On the developmente of new viedeo stations to monitor meteorite-droppimg events over Spain
The SPanish Meteor and Fireball Network (SPMN) is an interdisciplinary project involving several universi- ties and research centres with the aim to study meteor and fireball events occurring over Spain and the bordering ... -
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 ... -
On the development of robotic CCD video meteor observing station in Spain
Madiedo Gil, José María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Díaz Blanco, Manuel Jesús; Trigo Rodríguez, Josep María (2010)
Since 2006 the SPanish Meteor Network (SPMN) has set up several automated video stations in Spain for increasing the atmospheric cover-age of the already existing low-scan-rate all-sky CCD systems [1, 2]. However, in spite ... -
Analisys of a potential meteorite-dropping event over Spain in 2009
Díaz Blanco, Manuel Jesús; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Moreno-Ventas Bravo, Ignacio; López, L.; Escalona, F.; Gómez, Carmelo (2010)
The SPanish Meteor Network (SPMN) is performing a continuous monitoring of meteor activity over Spain and neighbouring countries. For this purpose we employ, among other systems, several video observing stations located ... -
Historical records of δ-Arietids superfireballs over Spain
Historical reports of bright fireballs are useful to better understand which meteoroid streams can be temptatively associated with meteoritedropping events [1]. We present here a preliminary analysis of a very remarkable ... -
Precise reflectante spectra of ordinary chondrites in the visible and uv : exploring the variability of s-class asteroidal spectra
Trigo Rodríguez, Josep María; Llorca, Jordi; Madiedo Gil, José María; Rivkin, A. S.; León, J. de; Pinilla Alonso, N. (2011)
Narrow-band spectrophotometry programs for the study of asteroids were initiated in the 1960s [1,2], which were able to identify clear absorption bands in the UV and visible, that were used later on in order to develop ... -
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 ... -
