U-Pb chronology of the Solar System's oldest solids with variable 238 U/ 235 U (2010, background): “Their temporal relationships have been the subject of many recent studies (Amelin et al. 2002, Bizzarro et al. 2004, Thrane et al. 2006, Amelin and Krot 2007, Bouvier et al. 2007, Connelly et al. 2008a, Jacobsen et al. 2008, Burkhardt et al. 2008, Bouvier and Wadhwa 2009, Krot et al. 2009, Nyquist…”
The primordial nucleus of comet 67P/Churyumov-Gerasimenko (2015, methodology): “Furthermore, the CAI-forming epoch could have been as short as 2×104–105 yr according to radiometric dating (Bizzarro et al. 2004; Thrane et al. 2006; Krot et al. 2008), presumably because sufficiently high temperatures for CAI formation only were met during the Class 0 and early Class I stages.”
THE LONG-TERM EVOLUTION OF THE GALACTIC DISK TRACED BY DISSOLVING STAR CLUSTERS (2010, background): “…to produce enough of it in situ (7Be, 26Al, 26Cl, and 53Mn; Duprat & Tatischeff 2008), or because timing constraints show that the element in question must have been injected in a single burst rather than produced over an extended period (26Al; Thrane et al. 2006; Connelly et al. 2008).”
EVIDENCE FOR MAGNESIUM ISOTOPE HETEROGENEITY IN THE SOLAR PROTOPLANETARY DISK (2011, background): “…ratio of (5.23 ± 0.13) × 10−5 (Jacobsen et al. 2008) has been inferred from Mg-isotope measurements of primitive meteorites and their components (Thrane et al. 2006; Villeneuve et al. 2009), and from the concordancy between 26Al–26Mg and 207Pb–206Pb ages obtained on the same chondritic…”
26Al‐26Mg isotope systematics of the first solids in the early solar system (2013, unknown): “…26Al-26Mg isochron diagrams indicates that the initial and principal aluminum-magnesium fractionation, i.e., the original formation of CV CAIs or their precursors by evaporation and condensation processes, occurred within a short period of time, ≤20 ka (Thrane et al. 2006; B. Jacobsen et al. 2008).”
Chondrules and the Protoplanetary Disk (2011, methodology): “The isochron defined by a suite of Allende CAIs on a plot of 26Mg/24Mg vs. 27Al/24Mg shows that CAIs probably formed in <105 years before any other class of planetary materials with an initial 26Al/27Al value of 5.8 × 10−5 (Bizzarro et al. 2004, 2005; Thrane et al. 2006).”
Chronology of the Solar System’s Oldest Solids (2008, background): “The Pb-Pb ages of CAIs from CV chondrites (4567.11 0.16 Myr; Amelin et al. 2006) is consistent with an early and brief duration of CAI formation ( 100,000 yr), perhaps during the infall stage of the protostellar evolution of the Sun (Bizzarro et al. 2004; Thrane et al. 2006).”
