Table A.2

Carbon and oxygen abundances (in dex) for our stars and the Sun, using the Kurucz Solar Atlas (Kurucz et al. 1984).

Star	log C_5052Å	log C_5380Å	log O_6158Å	log O_6300Å	[C/H]	[O/H]	[C/O]	C/O^e	Mg/Si^e

Kepler-10^b	8.48	8.47	8.92	—	−0.01 ± 0.05	0.21 ± 0.08	−0.22 ± 0.10	0.36	1.48
Kepler-10^a	8.52	8.44	—	—	0.00 ± 0.08	—	—	—	1.41
Kepler-93^a	8.35	8.59	—	—	−0.02 ± 0.16	—	—	—	1.32

C/O ratios derived using the average values for the oxygen and carbon abundances given by different lines.

^(e)

A/B = N_A/N_B = 10^log ε(A)/ 10^log ε(B), where log ε(A) and log ε(B) are the absolute abundances.
