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 ... -
Linking a fireball to its likely parent near earth object by means of orbital analysis software tools
Alonso, C.; Madiedo Gil, José María; Trigo Rodríguez, Josep María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Pastor, S.; Reyes, J. A. de los (2013)
The identification of their progenitor bodies is crucial to increase our knowledge on the origin and evolution of meteoroid streams. Traditionally, the similarity between two orbits has been used to link a given meteoroid ... -
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 ... -
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 ... -
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 ... -
A meteoroid from a Jupiter family comet recorded as a bright bolide in 2012
The continuous monitoring of meteor and fireball provides information about the origin and nature of meteoroids ablating in the Earth's atmosphere, but also about the mechanisms that deliver these materials to our ... -
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 ... -
A northerm may ophiuchid fireball imaged in 2012 in the framework of the Spanish meteor network
The Northern May Ophiuchids is a poorly known annual meteor shower whose activity period extends from April, 25 to May, 31, peaking around May 13 [1]. It is included in the IAU list of working meteor showers with code ... -
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 ... -
Observation of three twilight bolides in August, 2013 from Galicia, NW of Spain
The Spanish Meteor Network (SPMN) is dedicated to the study of fireballs and bolides which may cause meteorite falls on our planet. These meteorites allow us a better understanding of other bodies from the Solar System ... -
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 ... -
On the activity of the γ -Ursae Minorids meteoroid stream in 2010 and 2011
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Lyytinen, E.; Dergham, J.; Pujols, P.; Ortiz Moreno, José Luis; Cabrera Caño, Jesús (Oxford University Press, 2013)
Accurate orbital data obtained for the recently discovered γ -Ursae Minorids meteoroid stream during the 2010 and 2011 Spanish Meteor Network and Finnish Fireball Network observing campaigns are presented. In particular, ... -
On the chemical composition and orbit of a diurnal fireball
Toscano, F. M.; Madiedo Gil, José María; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Trigo Rodríguez, Josep María; Pastor, S.; Reyes, J. A. de los (2012)
In general, meteor and fireball imaging systems operate during the night, as these mostly employ high-sensitivity recording devices that get fully saturated even under twilight conditions. Lowsensitivity video cameras ... -
On the chemical nature and orbit of meteoroids from the omicron draconid stream
The omicron Draconids were first observed by Denning in the 19th Century [1]. The activity was, however, modest, with a zenithal hourly rate (ZHR) of about 10–12. Denning [2] also reported observations in 1929 but in ... -
