Comparing the reflectivity of ungrouped carbonaceous chondrites with those of short-period comets like 2P/Encke
(EDP Sciences, 2020-09-15)
Article
Open AccessAims. The existence of asteroid complexes produced by the disruption of these comets suggests that evolved comets could also produce high-strength materials able to survive as meteorites. We chose as an example comet ... -
Coordinated analysis of two graphite grains from the CO3.0 LAP 031117 meteorite: First identification of a CO Nova graphite and a presolar iron sulfide subgrain
(2016-07)
Article
Open AccessPresolar grains constitute remnants of stars that existed before the formation of the solar system. In addition to providing direct information on the materials from which the solar system formed, these grains provide ... -
Exploration and Utilisation of Lunar Resources affected by Space Weathering
(Universitat Politècnica de Catalunya, 2021-06)
Master thesis
Open AccessThis thesis aims to develop a study with regards to the exploration of the lunar surface through the resources produced by space weathering. Space weathering events shall be discussed, in terms of how the physical and ... -
Hydrogen burning of 29Si and its impact on presolar stardust grains from classical novae
(Institute of Physics (IOP), 2022-04-01)
Article
Open AccessPresolar stardust grains found in primitive meteorites are believed to retain the isotopic composition of stellar outflows at the time of grain condensation. Therefore, laboratory measurements of their isotopic ratios ... -
Impact hazard assessment from the automatic detection of meteoric and re-entry fireballs recorded by the SPMN network
(Universitat Politècnica de Catalunya, 2020-02-14)
Master thesis
Open AccessThe disruption of asteroids and comets can produce meteoroids that end up impacting the Earth’s atmosphere, creating shock waves or even excavating craters so they generate hazardous scenarios. In this thesis different ... -
Meteor observation with the SOURCE CubeSat – Developing a simulation to test on-board meteor detection algorithms
(Universitat Politècnica de Catalunya, 2022-04-29)
Conference lecture
Open AccessThe scientific mission objectives of the Stuttgart Operated University Research CubeSat for Evaluation and Education are meteor observation, measurement of the lower Earth's atmosphere during re-entry as well as technology ... -
Micrometeoroid events in LISA Pathfinder
(Institute of Physics (IOP), 2019-09-20)
Article
Open AccessThe zodiacal dust complex, a population of dust and small particles that pervades the solar system, provides important insight into the formation and dynamics of planets, comets, asteroids, and other bodies. We present a ... -
New observations on high-pressure phases in a shock melt vein in the Villalbeto de la Pena meteorite: insights into the shock behavior of diopside
(2019-09-27)
Article
Open AccessThe petrology and mineralogy of shock melt veins in the L6 ordinary chondrite host of Villalbeto de la Peña, a highly shocked, L chondrite polymict breccia, have been investigated in detail using scanning electron microscopy, ... -
On presolar stardust grains from CO classical novae
(Institute of Physics (IOP), 2018-03-10)
Article
Open AccessAbout 30%–40% of classical novae produce dust 20–100 days after the outburst, but no presolar stardust grains from classical novae have been unambiguously identified yet. Although several studies claimed a nova paternity ... -
Origin and minearology of Lunar meteorites. A study for lunar mining and resources exploitation
(Universitat Politècnica de Catalunya, 2020-06-22)
Master thesis
Open AccessIn recent years the Moon has become once again the target for many of the most ambitious space projects. Our satellite is expected to provide a permanent base by 2030s and open new possibilities for deep-space exploration ... -
Study: Numerical model of the trajectory of meteoroids
(Universitat Politècnica de Catalunya, 2020-01-15)
Bachelor thesis
Open AccessMeteoroids that enter the earth’s atmosphere and lighten up due to the collision with the air particles. In this study, a numerical model to simulate their trajectory through the Earth’s atmosphere has been developed. The ... -
The Berduc L6 chondrite fall: meteorite characterization, trajectory, and orbital elements
(2010)
Article
Restricted access - publisher's policyAbstract–The fall of the Berduc meteorite took place on April 7, 2008, at 01 h 02 min 28 s ± 1 s UTC. A daylight fireball was witnessed by hundreds of people from Argentina and Uruguay, and also recorded by an infrasound ... -
The reflectance spectra of CV-CK carbonaceous chondrites from the near-infrared to the visible
(Oxford University Press, 2021-10-01)
Article
Open AccessCarbonaceous chondrite meteorites are so far the only available samples representing carbon-rich asteroids and in order to allow future comparison with samples returned by missions such as Hayabusa 2 and OSIRIS-Rex, it is ... -
The Traspena meteorite: heliocentric orbit, atmospheric trajectory, strewn field, and petrography of a new L5 ordinary chondrite
(Oxford University Press, 2023-01-01)
Article
Open AccessThe Traspena meteorite fell on 2021 January 18 about 20¿km south-east of the city of Lugo (Galiza, Spain), shortly after a huge and bright fireball crossed the sky for 4.84¿s. Astrometric measurements obtained from the ... -
UV to far-IR reflectance spectra of carbonaceous chondrites - I. Implications for remote characterization of dark primitive asteroids targeted by sample-return missions
(2014-01-01)
Article
Restricted access - publisher's policyWe 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 ... -
White dwarf collisions, a promising scenario to account for meteoritic anomalies
(2018-09-04)
Article
Open AccessIt is commonly accepted that collisions between white dwarfs (WD) are rare events that only occur in the dense interior of globular clusters or in the dense outskirts around the central galactic black holes, and are therefore ...
