This [O iii] detection confirms the LBG with a spectroscopic redshift of z = 8.3118 \u00b1 0.0003, making this object one of the farthest galaxies ever identified spectroscopically. The observed 850 \u03bcm flux density of 137 \u00b1 26 \u03bcJy corresponds to a de-lensed total infrared (IR) luminosity of LIR=(1.7\u00b10.3)\u00d710^11L\u2299 if assuming a dust temperature of T dust = 50 K and an emissivity index of \u03b2 = 1.5, yielding a large dust mass of 4\u00d710^6M\u2299. The ultraviolet-to-far-IR spectral energy distribution modeling where the [O iii] emissivity model is incorporated suggests the presence of a young (\u03c4 age \u2248 4 Myr), star-forming (SFR \u2248 60M\u2299 yr^\u22121), moderately metal-polluted (Z \u2248 0.2Z \u2299) stellar component with a mass of M star = 3 \u00d7 10^8 M \u2299. An analytic dust mass evolution model with a single episode of star formation does not reproduce the metallicity and dust mass in \u03c4 age \u2248 4 Myr, suggesting a pre-existing evolved stellar component with M star ~ 3 \u00d7 10^9 M\u2609 and \u03c4age ~ 0.3 Gyr as the origin of the dust mass.", "subitem_description_type": "Abstract"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "IOP publishing"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.3847/1538-4357/ab0374", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2019.
