| Abstract: | Determining the accurate diameter of asteroids is crucial for understanding their physical properties and dynamical evolution. Traditional methods often rely on empirical relations between diameter, albedo, and absolute magnitude. However, these methods require accurate albedo measurements, which can be challenging to obtain.
In this study, we propose a novel approach to estimate asteroid diameters by combining polarimetric and photometric observations. We explore the relationship between asteroid diameter, polarization minimum, and absolute magnitude. By analyzing a comprehensive dataset of asteroids, we have derived an empirical formula that connects these parameters. This new method offers a potential advantage over traditional methods, as it does not require prior knowledge of the asteroid's albedo.
Our findings provide valuable insights into the scattering properties of asteroid surfaces and contribute to the development of more accurate techniques for asteroid characterization. This work has the potential to enhance our understanding of the asteroid population and its role in the solar system's history. |
