    Experimental Investigation of Ground Radiation on Dielectric and Brightness Temperature of Soil Moisture and Soil Salinity by Weizhen Wang, Leilei Dong, Chunfeng Ma, Long Wei, Feinan Xu, Jiaojiao Feng

    Published 2020-05-01
    “…The brightness temperature of the soil moisture and multilevel salinity was simulated by using the Q-H (parameter of polarization mixing and parameter of characterizing height) model and Holmes parameterization scheme of soil effective temperature. The results show that both the Dobson model and the GRMDM model can well reproduce the real part and imaginary part of the dielectric constant of non-saline soil, and the GRMDM model was better. …”

    Mass, Luminosity, and Stellar Age of Early-type Stars from the LAMOST Survey by Qida Li, Jianping Xiong, Jiao Li, Yanjun Guo, Zhanwen Han, Xuefei Chen, Chao Liu

    Published 2025-01-01
    “…Mass ( M ) and luminosity ( L ) are fundamental parameters of stars but can only be measured indirectly. Typically, effective temperature ( T _eff ), surface gravity ( $\mathrm{log}\ g$ ), and metallicity ([M/H]) are derived from stellar spectra, then M , L , and stellar age ( t ) can be obtained by interpolating in the grid of stellar evolutionary models. …”
