Study On Radio Radiation And Radiation Death Of Pulsar

We have studied the radio luminosity?L?and its radiation efficiency???of pulsars,explored the effect of energy loss rate?E?on the flux density,and further studies the radio pulsars in radio "grave areas".It was found that under a larger sample,the radio luminosity of pulsars and the energy loss rate remained a very weak correlation L-E0.058.A further study under monochromatic luminosity?also call pseudo-luminosities:Lv?found that the correlation of Lv—Eⁿ with radio frequencies at 400 MHz,800 MHz,1400 MHz,2000 MHz,and 3000 MHz is still very weak,n=0.036?0.097,and depends on the strength and frequency Irrelevant.This implies that the RS model needs major modification.Secondly,for radio pulsars with high-energy radiation,the dependence of Lv-Eⁿ becomes non-negligible,especially in radio pulsars with both X-ray and y-ray emissions,the correlations at frequencies of 1400 MHz and 400 MHz are Lv-E^0.87,Lv-E^1.04.Third,under similar energy loss rates,the radio luminosity of millisecond pulsars is an order of magnitude lower than that of normal pulsars,indicating that the radiation mechanisms of these two types of pulsars are likely to be different.In addition,it is found that the ?-E relationship between radiation efficiency and energy loss rate is not intrinsic pulsar physics.Therefore,the previous researchers used the upper limit of the radio pulsar's radiation efficiency to explain the conditions of the radio pulsar's death line.The upper limit of radio radiation efficiency cannot be equal to the death line Similarly,the correlation between radio radiation efficiency and characteristic age?TC?is also a result of data selection,not inherent pulsar physics.This paper finds that when the pulsar energy loss rate decreases below 10³⁴erg/s,the size of the pulsar energy loss rate limits the maximum value of the flow density,which meets the Smax ? E restriction trend at different frequencies.Due to this limitation,the flow density of low-energy-loss radio pulsars is generally smaller than other pulsars,so it is not easy to be observed.Therefore,after the sensitivity of the observation instrument is increased,a small amount of the original pulsar grave area appears Radio pulsars,the current radio pulsar grave area,cannot represent the death of their radio signals.In addition,by analyzing the correlation between the flow density and the energy loss rate at various frequencies,it is found that in the current observation,the flow density does not cause a significant cutoff at a certain energy loss rate value due to the decrease in the energy loss rate.That is,the radio signal of the pulsar will not disappear because the energy loss rate becomes smaller.Finally,the research on the selection effect of observations found that the low-energy-loss radio pulsar is a close-range source,which is more affected by the selection effect of instrument sensitivity.It implies that more pulsars can be found in this area.
