太阳引力参数$ \ mathrm {d}(gm _ {\ odot})/\ Mathrm {d} t $的变化率的估计值是从处理现代行星和飞机的现代位置来获得的。处理观察结果,并根据数值行星epmeris epm2019确定参数。通过辐射$ {\ dot m} _ {{\ odot} \ mathrm {rad}} $通过辐射$ {\ dot m} _ {\ dot m} $ {\ dot m} _ {在太阳$ {\ dot m} _ {{\ odot} \ mathrm {fall}} $。估计的相对值在$ -13.4 \ cdot 10^{ - 14} <(\ dot m _ {\ odot} /m _ {\ odot})_ {\ Mathrm {rad}+ \ mathrm {rad}+ \ mathrm {wind}获得了重力常数$ G $的变化率的以下范围:$ -2.9 \ cdot 10^{ - 14} <\ dot g /g < + 4.6 \ cdot 10^{ - 14} $每年$(3σ$)。新结果减少了$ g $变化的间隔,并缩小了替代重力理论与一般相对论的可能偏差的限制。
The estimate of the change rate of the solar gravitational parameter $\mathrm{d}(GM_{\odot})/\mathrm{d}t$ is obtained from processing modern positional observations of planets and spacecraft. Observations were processed and parameters were determined basing on the numerical planetary ephemeris EPM2019. The obtained annual decrease in solar mass $M_{\odot}$ accounts for the loss through radiation ${\dot M}_{{\odot}\mathrm{rad}}$, through the outgoing solar wind ${\dot M}_{{\odot}{\mathrm{wind}}}$, and for the material falling on the Sun ${\dot M}_{{\odot}\mathrm{fall}}$. The estimated relative value is within $-13.4\cdot 10^{-14} < (\dot M_{\odot} /M_{\odot})_{\mathrm{rad}+\mathrm{wind}+ \mathrm{fall}} < -8.7\cdot 10^{-14}$ per year. The following range for the change rate of the gravitational constant $G$ was obtained: $-2.9 \cdot 10^{-14} < \dot G /G < + 4.6 \cdot 10^{-14}$ per year $(3σ$). The new result reduces the interval for the change in $G$ and narrows the limits of possible deviations for alternative gravitational theories from general relativity.
