• NEUTRON-RICH CHROMIUM ISOTOPE ANOMALIES IN SUPERNOVA NANOPARTICLES (2010, background): “The presence of short-lived nuclides like 26Al (Lee et al. 1976, 1977; Jacobsen et al. 2008; MacPherson et al. 2010) and 60Fe (Birck & Lugmair 1988; Shukolyukov & Lugmair 1993; Tachibana & Huss 2003; Mostefaoui et al. 2005; Mishra et al. 2010) at the time of formation of meteorites supports birth…”
• U-Pb chronology of the Solar System's oldest solids with variable 238 U/ 235 U (2010, methodology): “The CAIs from both age groups have well preserved 26 Al26 Mg systems (Amelin et al. 2002, Jacobsen et al. 2008, Bouvier and Wadhwa 2010) that yield initial 26 Al/ 27 Al close to the canonical value and suggest simultaneous formation.”
• HETEROGENEOUS DISTRIBUTION OF 26Al AT THE BIRTH OF THE SOLAR SYSTEM (2010, methodology): “…this ratio to approximately 2% in the whole-rock CV CAIs have been interpreted as evidence for (1) uniform distribution of 26Al in the solar system and (2) a very short (<0.04 or <0.002 Ma) duration of CAI formation, respectively (e.g., Jacobsen et al. 2008;Davis et al. 2010; Larsen et al. 2011).”
• A Perspective from Extinct Radionuclides on a Young Stellar Object: The Sun and Its Accretion Disk (2011, methodology): “Isochrons calculated from measurements of bulk CAIs (Jacobsen et al. 2008) and individual minerals in a finegrained CAI (MacPherson et al. 2010a) give initial 26Al/27Al ratios of ~5.2 × 10−5.”
• Correlated accretion ages and ε54Cr of meteorite parent bodies and the evolution of the solar nebula (2014, methodology): “As for the Al-Mg system, an initial 26Al/27Al ratio of (5.23 0.13) 9 10 5 is reported from a bulk CAI isochron (Jacobsen et al. 2008).”
• Astrophysics with Extraterrestrial Materials (2016, background): “…the highest ratio of 26Al to 27Al (where 27Al is a stable isotope used to measure the relative abundance of the radioactive isotope), with typical (commonly referred to as canonical) values of 26Al/27Al ∼ 5.2 × 10−5 in such objects (Lee et al. 1977, MacPherson et al. 1995, Jacobsen et al. 2008).”

• The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites (2017, positive): “Most, but not all, measured CAIs are consistent with a uniform “canonical” level 26Al/27Al ∼ 5× 10−5 (MacPherson et al. 1995), a value now refined to 26Al/27Al ≈ 5.23× 10−5 (Jacobsen et al. 2008).”
• Melting and differentiation of early-formed asteroids: The perspective from high precision oxygen isotope studies (2017, background): “…invoking rapid, early accretion of achondritic parent bodies is that at “canonical” values of 26Al (26Al/27Al0 = 5.3 × 10−5) (MacPherson et al., 1995; Jacobsen et al., 2008), heating would have been too efficient and not have resulted in the formation of partial melt residues, as represented by…”
• The Compositional Structure of the Asteroid Belt (2015, background): “…on the assumption that the 26Al/27Al ratio of ~5x10-5 seen in most undisturbed CAIs represents the homogeneous initial ratio of the Solar System (e.g., Bizzarro et al., 2004; Hutcheon et al., 2009; Jacobsen et al. 2008; Kita and Ushikubo, 2012; Ushikubo et al., 2013; Villeneuve et al., 2009).”
