The measured time interval of celestial events is t, and t is only Earth time, not the original time t of celestial events. , the Earth time t must be converted into the original time t of the celestial event.
Measure the radial velocity u of a celestial body, it is not the eigenvelocity of the celestial body, the eigenvelocity is constant, but the apparent velocity changes, the celestial body moving towards the solar system is the blue-shifting celestial body, and the apparent velocity of the blue-shifting celestial body, year-on-year ratio One year slow.
Barnard’s Star is a blue-shifting celestial body, which is an example. The apparent velocity is slowing down every year. The apparent velocity of the first measurement is 110.8km/s, (ARICNS: 1916), and the apparent velocity of the second measurement is 110.8km/s. It is 106.8km/s (SIMBAD: 2000). From this paper, it is calculated that the intrinsic velocity of Barnard’s Star is 959.332km/s, and the apparent velocity in 2022 is 105.751km/s.
