Absolute colours and phase coefficients of trans-Neptunian objects: HV − HR and relative phase coefficients

The trans-Neptunian objects (TNOs) are small Solar System bodies at large distances from the Sun. As such, their physical properties are difficult tomeasure. Accurate determination of their physical parameters is essential to model and theorize the actual composition and distribution of the populati...

As such, their physical properties are difficult tomeasure. Accurate determination of their physical parameters is essential to model and theorize the actual composition and distribution of the population, and to improve our understanding of the formation and evolution of the Solar System. The objective of this work is to construct phase curves in two filters, V and R, of a large TNO sample obtaining absolute magnitudes (H) and phase coefficients (β), and study possible relations between them and other physical parameters (orbital elements, sizes, and albedos).We used our own data, together with data from the literature, to create the phase curves assuming an overall linear trend. We obtained new magnitudes for 28 TNOs, 28 in the V filter and 36 in the R filter. These magnitudes, together with data from the literature, allowed us to obtain absolutes magnitudes, 114 in the V filter and 113 in the R filter, of which 106 have both. From the search for correlations, we found a strong anticorrelation between H - H and Δβ = β - β, which is probably more related to surface structure than to composition or size of the objects. © 2018 The Author(s).Based in part on observations collected at the German-Spanish Astronomical Center, Calar Alto, operated jointly by Max-Planck-Institut fur Astronomie and Instituto de Astrofisica de Andalucia (CSIC).
