Table 1: The parameters for IRAS2 from jorgensen02.
Distance, d 220 pc
$L_{\rm bol}$ 16 $L_\odot$
$T_{\rm bol}$ 50 K
Envelope parameters:
Inner radius (T=250 K), $R_{\rm i}$ 23.4 AU
Outer radius, $R_{\rm 10 K}$a $1.2\times 10^{4}$ AU
Density at 1000 AU, n(H2) $1.5\times 10^{6}$ cm-3
Slope of density distribution, p 1.8
Mass, $M_{\rm 10 K}$a 1.7 $M_\odot $
CO abundance, [CO/H2] $2.6\times 10^{-5}$
aThe outer boundary is not well constrained, but taken to be the point where the temperature in the envelope has dropped to 10 K. The mass refers to the envelope mass within this radius.
