ULL and IAC Create Asteroid Photometric Catalog

The research, published in Monthly Notices of the Royal Astronomical Society, compiles data from 6,579 Solar System celestial bodies.

The University of La Laguna (ULL) and the Astrophysical Institute of the Canary Islands (IAC) have participated in the creation of one of the largest photometric catalogs of asteroids observed from Spain.

This study, published in the prestigious journal Monthly Notices of the Royal Astronomical Society, includes detailed information on 6,579 small celestial bodies, among them asteroids, comets, and irregular satellites. Most of these objects originate from the main belt, located between Mars and Jupiter.
Astrophysicist Carlos Hernández Monteagudo, affiliated with both the ULL and the IAC, played a key role in this research. The work is based on initial data from the Javalambre VARiability Survey (J-VAR), conducted using the telescope at the Javalambre Astrophysical Observatory.
After an exhaustive analysis of over 30,000 images, the team identified 131,966 moving objects, corresponding to the 6,579 celestial bodies mentioned. Data on the solar reflection of these objects were collected across seven different filters. These bodies are considered primordial remnants of the planetary formation process, making them crucial for understanding the origin and evolution of our Solar System.
The methodology used in the study employs multiband photometry to analyze brightness variations between different filters, allowing for the determination of asteroid surface properties and their classification. This enables the distinction of types such as carbon-rich asteroids or those dominated by silicates. The survey's design also facilitates the study of brightness variation over time, a phenomenon associated with asteroid rotation.
During the analysis, an uncataloged object was discovered. After reporting it to the Minor Planet Center, it was confirmed to be an irregular satellite of Jupiter. The research team plans to expand this catalog with new observations and refine asteroid classification in the future.
