Table 2:

The parameters for our final model for the circumstellar disk of HD 95881.
Parameter	Dust	PAHs
Inner disk radius ( $R_{\rm in}$ )	0.55 AU	0.55 AU
Outer disk radius ( $R_{\rm out}$ )	200 AU	200 AU
Inclination angle (i)	55 $^\circ$	55 $^\circ$
Position angle (major axis E of N)	103 $^\circ$	103 $^\circ$
Vertical density scaling parameter ( $\Psi$ )	2.75	2.75
Power law for the surface density (p)	1	1
Turnover point (R₀)	2.5 AU	$\infty$
Mass (M)	10 $^{-8}~M_{\odot}$	$5\times10^{-9}~M_{\odot}$

Notes. The carbon abundance was found to be 25% of the visible dust. The visible dust grains and the PAH molecules have a different spatial distribution.
