MINDS. Hydrocarbons detected by JWST/MIRI in the inner disk of Sz28 consistent with a high C/O gas-phase chemistry

Open Access

Table B.1

Parameters of the 0D slab models used to show the ‘detected’ molecules in the JWST-MIRI/MRS spectrum of Sz28 along with number of molecules $N$ $\[\mathcal{N}\]$ .

Molecule	T (K)	log₁₀ N (cm⁻²)	R_em (au)	$N$ $\[\mathcal{N}\]$
HCN	825	14.67	0.465	1×10⁴¹
HC₃N	250	15.5	0.159	2.4×10⁴⁰
CO₂+¹³CO₂	100	21.67	0.824
C₂H₆	475	19.3	0.025
CH₃	175	21	0.09
CH₄	450	20	0.05

Notes. These parameters do not report the best fits but are rather utilised to show confirmed detection of the molecular emissions in the Sz28 spectrum.
