Undergrad The brightness and linear polarization of pulsars

Click For Summary
SUMMARY

The discussion centers on the correlation between the linear polarization degree of pulsars and their brightness. A new pulsar radiation model published in the Monthly Notices of the Royal Astronomical Society (MNRAS) suggests a positive correlation, indicating that as pulsars become brighter, their linear polarization component also increases. However, the participants express uncertainty regarding existing statistical research on this correlation, highlighting a gap in the literature that warrants further investigation.

PREREQUISITES

I have a question to ask everyone.

Is there a positive correlation between the linear polarization degree of pulsars and their brightness in statistics? Or, is it true that the brighter the pulsar, the greater the linear polarization component?

Pulsars are all about the same size so their brightness I expect depends mainly on their temperature, which decreases slowly with age. I dunno about polarization.
 
Not long ago, we published a new pulsar radiation model at MNRAS (https://doi.org/10.1093/mnras/stae909).
According to our model, it is speculated that the linear polarization component of pulsars should be statistically positively correlated with theirs brightness. But we don't know if anyone has conducted statistical research in this area. So I would like to ask if anyone has seen any reports on this topic.
