• The deuterium abundance in Jupiter and Saturn from ISO-SWS observations (2001, methodology): “Saturn’s atmosphere appears depleted in helium, and the most recent He/H ratios in Jupiter and Saturn (von Zahn et al. 1998; Conrath & Gautier 2000) can be quantitatively explained by the helium unmixing in Saturn (Hubbard et al. 1999).”
• Shock Compression of Deuterium and the Interiors of Jupiter and Saturn (2004, methodology): “The division of the hydrogenhelium envelopes into an inner and an outer part arises because the observed helium atmospheric abundances in Jupiter (von Zahn et al. 1998) and Saturn (Conrath & Gautier 2000) are reduced compared to the protosolar value (Bahcall et al. 1995).”
• Helioseismology and Solar Abundances (2007, methodology): “The Voyager spacecraft was used to measure the abundance ratio of helium to hydrogen in Jupiter and Saturn and it was found to be 0.057 ± 0.013 and 0.016 ± 0.013 respectively (Gautier et al. 1981; Conrath et al. 1984), lower than expected value.”
• The Interior Structure, Composition, and Evolution of Giant Planets (2009, background): “Fortney & Hubbard (2003) next inverted the problem to derive an ad-hoc phase diagram that could simultaneously explain Saturn’s current luminosity as well as its current atmospheric helium abundance (Conrath & Gautier 2000).”
• THE DEUTERIUM-BURNING MASS LIMIT FOR BROWN DWARFS AND GIANT PLANETS (2010, unknown): “In a reanalysis of Voyager data, Conrath & Gautier (2000) found the abundance in Saturn to be in the range 0.18-0.25.”
• The Properties of Hydrogen and Helium Under Extreme Conditions (2011, background): “The EOS of hydrogen-helium mixtures is a key ingredient for the interior models of Jupiter, Saturn and other hydrogen-rich planets.”
