# New phase-magnitude curves for some Main Belt asteroids, fit of different photometric systems and calibration of the albedo - photometry relation

## TL;DR

This study presents new phase-magnitude curves for Main Belt asteroids, aiming to improve photometric system calibration and explore relations between phase-magnitude parameters and asteroid albedo, with implications for Gaia data analysis.

## Contribution

It provides new observational data and initial calibration efforts for asteroid phase-magnitude relations, enhancing the understanding of asteroid photometry.

## Key findings

- New phase-magnitude curves for selected asteroids
- Calibration of the $(H, G_1, G_2)$ photometric system
- Potential relations between phase-magnitude parameters and albedo

## Abstract

Results of photometric observations of a small sample of selected Main Belt asteroids are presented. The obtained measurements can be used to achieve a better calibration of the asteroid photometric system $(H, G_1, G_2)$ adopted by the IAU, and to make comparisons with best-fit curves that can be obtained using different photometric systems. The new data have been obtained as a first feasibility study of a more extensive project planned for the future, aimed at obtaining a reliable calibration of possible relations between some parameters characterizing the phase-magnitude curves and the geometric albedo of asteroids. This has important potential applications to the analysis of asteroid photometric data obtained by the Gaia space mission.
