      The 2011 October Draconids outburst-I. Orbital elements, meteoroid fluxes and 21P/Giacobini-Zinner delivered mass to Earth  [Article]

      Trigo-Rodríguez, Josep Maria; Madiedo Gil, José María; Williams, Iwan P.; Dergham, Joan; Cortés, Jordi; Castro-Tirado, A. J.; Ortiz, J. L.; Zamorano G., Jaime; Ocaña, Francisco; Izquierdo, Jaime (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  [Article]

      Madiedo Gil, José María; Trigo-Rodríguez, Josep Maria; Konovalova, Natalia A.; Williams, Iwan P.; Castro-Tirado, A. J.; Ortiz, J. L.; Cabrera Caño, Jesús María (Oxford University Press, 2013)
      On 2011 October 8, 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 an ...

      The Northern χ -Orionid meteoroid stream and possible association with the potentially hazardous asteroid 2008XM1  [Article]

      Madiedo Gil, José María; Trigo-Rodríguez, Josep Maria; Williams, Iwan P.; Ortíz, José L.; Cabrera Caño, Jesús María (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 ...

      UV to far-IR reflectance spectra of carbonaceous chondrites - I. Implications for remote characterization of dark primitive asteroids targeted by sample-return missions  [Article]

      Trigo-Rodríguez, Josep Maria; Moyano-Cambero, Carles E.; Llorca, Jordi; Fornasier, Sonia; Barucci, Maria Antonietta; Belskaya, Irina N.; Martins, Zita; Rivkin, Andrew S.; Dotto, Elisabetta; Madiedo Gil, José María; Alonso-Azcárate, Jacinto (Oxford University Press, 2013)
      We analyse here a wide sample of carbonaceous chondrites from historic falls (e.g. Allende, Cold Bokkeveld, Kainsaz, Leoville, Murchison, Murray, Orgueil and Tagish Lake) and from NASA Antarctic collection.With the analysis ...
