An experimental study on the compaction and collapsible behaviour of a flood defence embankment fill
(2014-09)
Article
Accés restringit per acord de confidencialitatWith renewed interest in the performance of flood embankments globally, it is important that the performance of fills in conditions similar to 'as-constructed' are scrutinised. The fill material investigated in this study ... -
Constraining the double-degenerate scenario for Type Ia supernovae from merger ejected matter
(2015-03-01)
Article
Accés obertWe follow the mass expelled during the WD-WD merger process in a particular case of the double-degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting ... -
Effects of sea level rise on the formation and drowning of shoreface-connected sand ridges, a model study
(2014-06-01)
Article
Accés restringit per política de l'editorialShoreface-connected sand ridges occur on many storm-dominated inner shelves. These rhythmic features have an along-shelf spacing of 2-10 km, a height of 1-12 m, they evolve on timescales of centuries and they migrate several ... -
Modeling the response of shoreface-connected sand ridges to sand extraction on an inner shelf
(2014-05-01)
Article
Accés restringit per política de l'editorialShoreface-connected sand ridges are rhythmic bedforms that occur on many storm-dominated inner shelves. The ridges span several kilometers, are a few meters high, and they evolve on a timescale of centuries. A process-based ... -
Monte Carlo simulations of post-common-envelope white dwarf plus main sequence binaries: comparison with the SDSS DR7 observed sample
(2014-06-01)
Article
Accés obertContext. Detached white dwarf + main sequence (WD+MS) systems represent the simplest population of post-common envelope binaries (PCEBs). Since the ensemble properties of this population carries important information about ... -
Population Synthesis of Post-Common Envelope White-Dwarf-Main-Sequence Binaries in the Sloan Digital Sky Survey
(Astronomical Society of the Pacific, 2011-09-01)
Capítol de llibre
Accés obertWe present preliminary results of detailed Monte Carlo simulations of the population of white dwarf-main sequence binary systems in the Sloan Digital Sky Survey Data Release 7 (SDSS DR7). We have used the most up-to-date ... -
Smoothed particle hydrodynamics simulations of the core-degenerate scenario for Type Ia supernovae
(2015-07-01)
Article
Accés obertThe core-degenerate scenario for Type Ia supernovae involves the merger of the hot core of an asymptotic giant branch star and a white dwarf, and might contribute a non-negligible fraction of all thermonuclear supernovae. ... -
Spiral instability can drive thermonuclear explosions in binary white dwarf mergers
(2015-02-10)
Article
Accés obertThermonuclear, or Type Ia supernovae (SNe Ia), originate from the explosion of carbon-oxygen white dwarfs, and serve as standardizable cosmological candles. However, despite their importance, the nature of the progenitor ... -
The response of a helium white dwarf to an exploding Type Ia supernova
(2015-05-01)
Article
Accés obertWe conduct numerical simulations of the interacting ejecta from an exploding CO white dwarf (WD) with a He WD donor in the double-detonation scenario for Type Ia supernovae (SNe Ia), and study the possibility of exploding ... -
ZK60 alloy processed by ECAP: Microstructural, physical and mechanical characterization
(2014-01-31)
Article
Accés restringit per política de l'editorialLately, magnesium alloys have been extensively investigated through severe plastic deformation (SPD) methods in order to extend their application to structural components. In the present work, as-extruded ZK60 magnesium ...
