Methodologies for 176Lu-176Hf Analysis of Zircon Grains from the Moon and Beyond
Xi Chen, Nicolas Dauphas, Zhe J. Zhang +6
Zircons are found in extraterrestrial rocks from the Moon, Mars, and some differentiated meteorite parent-bodies. These zircons are rare, often of small size, and have been affecte…
Science Priorities for the Extraction of the Solid MSR Samples from their Sample Tubes
N. Dauphas, S. S. Russell, D. Beaty +20
Preservation of the chemical and structural integrity of samples that will be brought back from Mars is paramount to achieving the scientific objectives of MSR. Given our knowledge…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
Oxygen and Aluminum-Magnesium Isotopic Systematics of Presolar Nanospinel Grains from CI Chondrite Orgueil
Nan Liu, Nicolas Dauphas, Sergio Cristallo +2
Presolar oxide grains have been previously divided into several groups (Group 1 to 4) based on their isotopic compositions, which can be tied to several stellar sources. Much of av…
Earth's accretion inferred from iron isotopic anomalies of supernova nuclear statistical equilibrium origin
Timo Hopp, Nicolas Dauphas, Fridolin Spitzer +2
Nucleosynthetic Fe isotopic anomalies in meteorites may be used to reconstruct the early dynamical evolution of the solar system and to identify the origin and nature of the materi…
Terrestrial planet formation by torque-driven convergent migration of planetary embryos
M. Brož, O. Chrenko, D. Nesvorný +1
Massive cores of the giant planets are thought to have formed in a gas disk by accretion of pebble-size particles whose accretional cross-section is enhanced by aerodynamic gas dra…
