Summary
CCD photometry observations revealed potential binary asteroid systems within the Hungaria group. One object, (15822) 1999 TV15, shows promising signs of being a new binary discovery.
Area of Science:
- Asteroid science
- Observational astronomy
- Photometry
Background:
- Binary asteroids are crucial for understanding solar system formation and evolution.
- The Hungaria asteroid group is a dynamically interesting population.
Purpose of the Study:
- To investigate four suspected or confirmed binary asteroids using CCD photometry.
- To identify new binary asteroid systems and gather data for existing ones.
Main Methods:
- Conducted CCD photometry observations at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS).
- Analyzed lightcurves to detect secondary periods and mutual events indicative of binary systems.
Main Results:
- Observed four Hungaria family members: 5968 Trauger, (11217) 1999 JC4, (15822) 1999 TV15, and (76818) 2000 RG79.
- (15822) 1999 TV15 exhibited mutual events, suggesting a likely new binary discovery.
- 5968 Trauger showed a possible satellite event, while (11217) 1999 JC4 indicated a strong secondary period.
Conclusions:
- The study provides new observational data for four Hungaria asteroids.
- Reinforces the potential for binary asteroid discoveries within this population.
- Contributes to the ongoing modeling and understanding of binary asteroid systems.
