AI 中文摘要
我们研究了由三参数广义熵重构的静态黑洞的吸积和对中微子敏感的热特征。这种构建是基于热力学设计的：熵变形未映射到径向坐标重新定义或规定的类雷斯纳 - 诺德斯特龙修正。广义熵确定了视界响应因子$\Xi_h = dS_G/dS|_{S_h}$。通过要求其表面重力温度重现广义热力学温度来重构有效外部几何。计算了光子球、临界阴影尺度等多种物理量。正的$\lambda_G$使光子球和内最稳定圆轨道向内移动等，负的$\lambda_G$则相反。最后用无量纲温度矩对中微子部分进行保守建模，发现随着温度指数升高，熵诱导的盘变形愈发明显。
英文摘要
We study accretion and thermal diagnostics motivated by neutrino processes for a static black hole reconstructed from a three-parameter generalized entropy. The construction is thermodynamic by design: the entropy deformation is not mapped to a radial-coordinate redefinition or to a prescribed Reissner--Nordström-like correction. Instead, the generalized entropy fixes the horizon response factor $Ξ_h=dS_G/dS|_{S_h}$. The effective exterior geometry is then reconstructed by requiring its surface-gravity temperature to reproduce the generalized thermodynamic temperature. As a result, the metric preserves the horizon area and the Schwarzschild asymptotics, and reduces smoothly to Schwarzschild when $Ξ_h\to1$. The entropy response is encoded in $λ_G=1/Ξ_{\rm h}-1$, whereas the exterior radial dependence requires an additional localization prescription. The detailed accretion analysis is performed for the power-law family $h(x)=x^{-p}$, with $p\geq2$. Within this reconstruction family, positive $λ_G$ moves the photon sphere and ISCO inward, decreases the critical shadow scale, raises the radiative efficiency, and concentrates the energy release toward the inner disk, while negative $λ_G$ produces the opposite trend. A complementary comparison with exponential and rational localization functions shows that this qualitative ordering is preserved for the profiles tested, although the magnitude of the strong-field shifts remains profile-dependent. Finally, the neutrino-motivated thermal sector ...
