Comparing the reflectivity of ungrouped carbonaceous chondrites with those of short-period comets like 2P/Encke
(EDP Sciences, 2020-09-15)
Article
Accés obertAims. 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 ... -
Exploration and Utilisation of Lunar Resources affected by Space Weathering
(Universitat Politècnica de Catalunya, 2021-06)
Projecte Final de Màster Oficial
Accés obertThis 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
Accés obertPresolar 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)
Projecte Final de Màster Oficial
Accés obertThe 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)
Comunicació de congrés
Accés obertThe 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 ... -
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
Accés obertThe 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, ... -
Origin and minearology of Lunar meteorites. A study for lunar mining and resources exploitation
(Universitat Politècnica de Catalunya, 2020-06-22)
Projecte Final de Màster Oficial
Accés obertIn 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)
Treball Final de Grau
Accés obertMeteoroids 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 ... -
