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 ... -
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 ... -
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 Puerto Lapice eucrite fall phenomenon
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Llorca, Jordi; Borovicka, Jiri; Izquierdo Gómez, Jaime; Zamorano, J.; Ocaña Gónzalez, Francisco (2008)
The fall of the Pu erto Lápice eucrite occurred in the afternoon of May 10, 2007, 17h57m20±2s UTC. This impressive daylight bolide was witnessed by thousands of people from Spain, and is being carefully studied in the ... -
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 ... -
Spanish meteor network : 2006 all-sky and video monitoring highlights
Trigo Rodríguez, Josep María; Madiedo Gil, José María; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Gural, P. S.; Llorca, Jordi; Fabregat Llueca, Juan; Vítek, Stanislav; Pujols, P.; Troughton, Blanca (2007)
We previously reported [1] the first steps in the development of the SPanish Meteor Network (SPMN) by using innovative low-scan all-sky CCD cameras that are reaching +2/+3 meteor limiting magnitude [1]. During 2006 new ...
