The CORALIE survey for southern extrasolar planets XVI. Discovery of a planetary system around HD 147018 and of two long period and massive planets orbiting HD 171238 and HD 204313

We report the detection of a double planetary system around HD 140718 as well as the discovery of two long period and massive planets orbiting HD 171238 and HD 204313. Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m E ...

The origin of 60Fe and other short-lived radionuclides in the early solar system

Anders Meibom

Establishing the origin of short-lived radionuclides (SLRs) with half-lives ≤100 Myr has important implications for the astrophysical context of our Sun's birth place. We review here the different origins proposed for the variety of SLRs present in the sol ...

Volatilization induced by impacts recorded in Zn isotope composition of ureilites

Philippe Gillet, Pierre Beck

Ureilites are ultramafic achondrites formed by igneous processes early in the history of the Solar System. Ureilites are heavily depleted in volatile elements, probably by evaporation at the surface of the ureilite parent body: however the moderately volat ...

Barriers and Needs for Building Integration of Solar Thermal and Photovoltaics

Maria Cristina Munari Probst

The International Energy Agency (IEA) Task 41 is conducting an international survey concerning the integration of solar energy systems and architecture in order to identify barriers that architects are facing in incorporating active solar technologies in t ...

Regeneration of oxidized photosensitizers: Quantum-chemical portray of a general mechanism

Ulf Anders Hagfeldt

The direct conversion of sun light to elec. power in mol. photoelectrochem. systems, aka Gratzel solar cells, is one of the promising "solar technologies" for utilization of abundant solar light as alternative energy source. Considering advantages of Gratz ...

Critical particle concentration in electrophoretic deposition

Stefano Mischler, Johann Michler

The role of particle concentration in electrophoretic deposition (EPD) was investigated with two different suspension systems. The first system consisted of positively charged TiO2 nanoparticles dispersed in isopropanol with 1 vol% water. The second system ...

Ad-Hoc Wireless Sensor Networks For Exploration Of Solar-System Bodies

Mihai Adrian Ionescu, Herbert Shea, Pierre-André Farine, Cyril Botteron, Valentin Mitev

In this work, we evaluate the exploration of the Solar system by ad-hoc wireless sensor networks (WSN), i.e. networks where all nodes (either moving or stationary) can both provide and relay data. The two aspects of self-organization and localization are t ...

Pristine extraterrestrial material with unprecedented nitrogen isotopic variation

Anders Meibom

Pristine meteoritic materials carry light element isotopic fractionations that constrain physiochemical conditions during solar system formation. Here we report the discovery of a unique xenolith in the metal-rich chondrite Isheyevo. Its fine-grained, high ...

Proto-Planetary Disk Chemistry Recorded By D-Rich Organic Radicals In Carbonaceous Chondrites

Anders Meibom, François Robert

Insoluble organic matter (IOM) in primitive carbonaceous meteorites has preserved its chemical composition and isotopic heterogeneity since the solar system formed similar to 4.567 billion years ago. We have identified the carrier moieties of isotopically ...

SUPERNOVA PROPAGATION AND CLOUD ENRICHMENT: A NEW MODEL FOR THE ORIGIN OF Fe-60 IN THE EARLY SOLAR SYSTEM

Anders Meibom

The radioactive isotope Fe-60 (T-1/2 = 1.5 Myr) was present in the early solar system. It is unlikely that it was injected directly into the nascent solar system by a single, nearby supernova (SN). It is proposed instead that it was inherited during the mo ...
