A 13 kg meteoroid from comet 21P/Giacobini-Zinner recorded as a bolide during the 2011 draconid outburst
(2012)The parent body of the Draconid meteoroid stream is the short period comet 21P/Giacobini-Zinner. This cometary debris gives rise to an annual display of meteors from about October 6 to October 10, with a maximum activity ... -
The 2006 Orionid outburst imaged by all-sky CCD cameras from Spain: meteoroid spatial fluxes and orbital elements
(Oxford University Press, 2007)By using high-resolution low-scan-rate all-sky CCD cameras, the SPanish Meteor Network (SPMN) detected an outburst of Orionid meteors associated with comet 1P/Halley on 2006 October 20–21. This detection was made possible ... -
A 2010 fireball produced by a meteoroid from comet 1P/Halley
(2013)Comet 1P/Halley is the source of the Orionid and η Aquariid meteor showers [1]. The latter one takes place during the second encounter of the Earth with 1P/Halley debris in October, when our planet is as close as ... -
A 2010 superbolide produced by a meteoroid from a short period comet
(2013)In 2009 our team established a me- teor observing station in the Sierra Nevada Astronomi- cal Observatory (Granada, Spain), with the aim to monitor meteor and fireball activity over the south of the Iberian Peninsula ... -
The 2011 Giacobinid outburst : meteoroid flux determination and orbital data by using video imagery from the Spanish fireball network
(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
(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
(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 ... -
A 2012 geminid fireball : atmospheric trajectory, orbit and spectrum
(2013)Asteroid (3200) Phaeton is the par- ent body of the Geminid meteoroid stream. These par- ticles give rise to one of the strongest annual meteor showers, with an activity period that extends from Nov. 27 to Dec. 28, ... -
The 2012 geminids balloon-borne mission over Spain
(2013)Observing meteors from the stratosphere improves detection efficiency thanks to much lower extinction. Previous airborne missions have already monitored meteor outbursts. However due to their cost these missions are ... -
A 2012 taurid bolide imaged in the framework of the Spanish fireball network
(2013)In 2010 the Spanish Meteor Net- work (SPMN) started a special program to obtain very precise orbital information on 2P/Encke meteoroids that is currently the focus of the author master thesis [1, 2]. The orbital ... -
A 5-years fireball monitoring experience of an Astronomical Association Operating a high-sensitivity video station in the framework of the Spanish meteor netxork
(2013)A continuous monitoring of meteors and fireballs appeared all over Spain is being made currently from 25 stations operated in the framework of the Spanish Meteor and Fireball Network (SPMN) [1-4]. This observational ... -
AFM and SEM assessment of lubricating grease microstructures : influence of sample preparation protocol, frictional working conditions and composition
(Springer Verlag, 2016)The microstructure of lubricating greases greatly conditions their in-service performance. In that sense, optimal testing protocols are required in order to accomplish their correct morphological characterization. This ... -
Alternative raw materials of celullose pulp from agroforestry residues
(Network on Rerycling of Agricultural, Municipal and Industrial Residues in Agriculture, 2004-10)Vegetables of alternative cultures to the agro-alimentary ones are used, for the paste manufacture for paper, with the purpose of diminishing the wood consumption and the imports of paste and paper, as well as diminishing ... -
Amorphous Al-Ti Powders Prepared by Mechanical Alloying and Consolidated by Electrical Resistance Sintering
(MDPI, 2019-10)A novel processing method for amorphous Al50Ti50 alloy, obtained by mechanical alloying and subsequently consolidated by electrical resistance sintering, has been investigated. The characterisation of the powders and the ... -
An Earth-grazing fireball from the Daytime ζ -Perseid shower observed over Spain on 2012 June 10
(Royal Astronomical Society, 2016)On 2012 June 10, an Earth-grazer meteor which lasted over 17 s with an absolute magnitude of -4.0 ± 0.5 was observed over Spain. This work focuses on the analysis of this rare event which is, to our knowledge, the faintest ... -
An Experimental-Based Approach to Construct the Process Design Space of a Freeze-Drying Process: An Effective Tool to Design an Optimum and Robust Freeze-Drying Process for Pharmaceuticals
(Elsevier, 2020)The application of quality by design (QbD) is becoming an integral part of the formulation and process development for pharmaceutical products. An essential feature of the QbD philosophy is the design space. In this sense, ... -
Analisys of a datyme fireball witnessed on August 10, 2012 over the Iberian Peninsula
(2013)Meteorite-dropping bolides are rare events that may provide unique samples coming from other bodies in the Solar System. For this reason, the analysis of such events is one of the aims of the SPanish Meteor Network ... -
Analisys of a June Lyrid fireball
(2013)The June Lyrids (JLY) were first observed by Dvorak in 1966 [1]. Its activity period was determined to extend from June 11 to June 21, peaking on June 16 with a zenithal hourly rate of about 9. However, evidence for ... -
