Uncertainties and robustness of the ignition process in type Ia supernovae

Table 2:

Main features of the two additional WD models computed to investigate the effects of changing the burning rate (quantities are same as in Table 1).
Model	$T_{\rm c}$ [ $10^8~{\rm K}$ ]	$\rho_{\rm c}$ [ $10^9~{\rm g\ cm^{-3}}$ ]	g [ $10^9~{\rm cm\ s^{-2}}$ ]	$r_{{\rm b}}$ [km]
3.1	7.68	2.20	6.23	150
3 ^a	7.63	2.08	5.90	154
3.2	7.59	2.00	5.20	164

Notes. ^(a) As for model 3, the stellar evolution code stalls shortly before the actual criterion for ignition is met, hence these values result of an extrapolation from about 5% lower temperature models. However, we do not expect the extrapolation errors to change much either the absolute or the relative values of the numbers presented in this table.
