The meteorite exhibits a bulk density of 3.476 g\/cm3, a grain density of 3.69 g\/cm3, and porosity of 5.80%. DSC revealed the presence of troilite (FeS) with \u03b1\/\u03b2 and \u03b2\/\u03b3 phase transition shifts across different regions, indicating a temperature gradient during atmospheric entry, with a calculated troilite content of 4.59 wt.%. Specific heat capacity was found to be 740 \u00b1 33 Jkg\u22121K\u22121 at room temperature, while volumetric heat capacity ranged from 1.90 \u00b1 0.11 MJ\/(m3K) at 200 K and 2.57 1.90 \u00b1 0.11 MJ\/(m3K) at 300 K. The atom-molar heat capacity increased from 12.64 J\/(molK) to 17.41 J\/(molK) across the same temperature range. Thermal diffusivity was estimated to be 1.25 \u00b1 0.36\u22c510\u22126 m2s\u22121 in air and 0.71 \u00b1 0.03\u22c510\u22126 m2s\u22121 in a vacuum. Thermal conductivity is 2.6 \u00b1 0.6 Wm\u22121K\u22121 in air and 1.8 \u00b1 0.2 Wm\u22121K\u22121 in vacuum at 300 K for both. Thermal inertia predicted for vacuum is equal to 1.84 \u00b1 0.14 \u22c5 103 Js\u22121\/2K\u22121m\u22122 at 200 K, and 2.15 \u00b1 0.18 \u22c5 103 Js\u22121\/2K\u22121m\u22122 at 300 K. A minimal mass loss of 0.62% up to 1200 \u00b0C, with water and hydrogen contents of 0.32 and 0.032%, respectively, suggests low volatile content. These results provide key insights into heat transfer behavior and the parent body evolution of the Bursa meteorite.”<\/p>\n","protected":false},"excerpt":{"rendered":"
