    Determining Symmetry Properties of Gravitational Fields of Terrestrial Group Planets by R.A. Kascheev, I.O. Novlyanskaya

    Published 2016-09-01
    “…According to the results of calculations carried out for the Earth, Moon, Mars, and Venus, the values of the criteria vary considerably for different types of symmetries and for different planets. It means that the specific value of each criterion corresponding to a particular celestial body is indicative of the properties and internal structure characteristics of the latter and, therefore, it can be used as a tool for comparative planetology. …”

    FEA and Structural Optimization of the Planet Carrier of the Speed-increase Gearbox by Pan Jinkun, Geng Feng

    Published 2015-01-01
    “…On the purpose of lightweight design,on the condition that it meets the strength and stiffness requirements the designer began to structural optimization of the planet carrier of speed-increase gearbox.First,the analysis of the strength and stiffness of planet carrier is carried out,and then the structure size which posts an important impact on planet carrier is decided as the design variable.Second,using high-end mesh morph software,the parameterized model of grid is established,and then go further,the optimized model of planet carrier on the purpose of decreasing its weight is built.Finally,the optimized analysis is carried out in combination of Isight multidisciplinary optimization software,the reasonable design plan for lightweight of planet carrier is obtained.The modal analysis towards the optimized planet carrier is carried out,and its natural frequency completely avoid meshing frequency,so as to avoid resonance phenomenon.…”

    Most High-density Exoplanets Are Unlikely to Be Remnant Giant Planet's Cores by Zifan Lin, Saverio Cambioni, Sara Seager

    Published 2025-01-01
    “…Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories—metal-rich formation hypothesis and naked core hypothesis—that explain how formation and evolution can alter the compositions and structures of rocky planets to diverge from their primordial building blocks. …”

    Ultraviolet Photometry and Habitable Zones of over 2700 Planet-hosting Stars by Xue Li, Song Wang, Henggeng Han, Jifeng Liu

    Published 2025-01-01
    “…Stellar ultraviolet (UV; 100–3000 Å) radiation may play a crucial role in determining the habitability of their planets. In this paper, we conducted a detailed analysis of the UV photometry of over 2700 host stars with confirmed planets, using observational data from the Galaxy Evolution Explorer and Swift Ultraviolet/Optical Telescope missions. …”

    Doppler cross-correlation spectroscopy as a path to the detection of Earth-like planets by Mayor, Michel

    Published 2023-06-01
    “…Gradually the accuracy of the new generation of spectrographs using cross-correlation is improved from 300 m/s to 0.1 m/s. ...An idea that will contribute in an important way to the discovery of 51 Pegasi b and several hundreds of planetary systems.Will visible or infrared cross-correlation spectrographs today be able to detect rocky planets in the habitable zone associated with their host star?…”
