Small bodies NIR multiwaves phase curves

We compute the absolute magnitudes using two photometric models: the HG12 and the linear model. We employ a combination of Bayesian inference and Monte Carlo sampling to calculate the probability distributions of the absolute magnitudes and their corresponding phase coefficients. We use the combination of four near-infrared photometric catalogs to create our input database.

We produced the first catalog of near-infrared magnitudes. We obtained absolute magnitudes for over 10000 objects (with at least one absolute magnitude measured), with about 180 objects having four absolute magnitudes. We confirmed that a linear model that fits the phase curves produces accurate results.

Since a linear behavior well describes the curves, fitting to a restricted phase angle range (in particular, larger than 9.5{deg}) does not substantially affect the results. Finally, we also detect a phase-coloring effect in the near-infrared, as observed in visible wavelengths for asteroids and trans-Neptunian objects.
