Abstract:
Trans-Neptunian objects (TNOs) represent a new frontier in the study
of our Solar System. In particular, the investigation of their
rotational properties can provide important hints about their internal
structure and collisional evolution.
We expand the limited sample of TNOs with known rotation rates, and
improve the knowledge of the physical nature of these bodies.
Description:
We carried out photometric observations of 5 TNOs (144897 2004 UX10,
145451 2005 RM43, 145453 2005 RR43, 2003 UZ117, and 2003
UZ413) using the New Technology Telescope of the European Southern
Observatory. Results. We determined the spin rates of four targets,
while only an estimation of the period was possible for 2003 UZ117.
