Analysis of 25 mutual eclipses and occultations between the Galilean satellites observed from Brazil in 2009
A. Dias-Oliveira,R. Vieira-Martins,Marcelo Assafin,Julio Camargo,Felipe Braga-Ribas,D. N. da Silva Neto,H. S. Gaspar,P. M. Pires dos Santos,R. C. Domingos,L. A. G. Boldrin,Andre Izidoro,J. P. S. Carvalho,Rafael Sfair,Jarbas Cordeiro Sampaio,Othon C. Winter +14 more
TL;DR: In this article, the authors used the Oren-Nayar reflexive model to map the inhomogeneous light scattering on the surface of the satellites of the Earth and fitted the occultation and eclipse light curves using semi-analytical models that take into account the gradual decrease of light over the shadow, the solar limb darkening and the solar phase angle.
Astrometry of mutual approximations between natural satellites. Application to the Galilean moons
B. E. Morgado,B. E. Morgado,Marcelo Assafin,R. Vieira-Martins,R. Vieira-Martins,Julio Camargo,A. Dias-Oliveira,A. R. Gomes-Júnior +7 more
TL;DR: In this paper, the authors developed a method that can provide accurate astrometric data for natural satellites, the mutual approximations, which can be applied when any two satellites pass close by each other in the apparent sky plane.
Astrometry of the main satellites of Uranus: 18 years of observations
Julio Camargo,F. P. Magalhaes,F. P. Magalhaes,R. Vieira-Martins,Marcelo Assafin,Felipe Braga-Ribas,Felipe Braga-Ribas,A. Dias-Oliveira,G. Benedetti-Rossi,A. R. Gomes-Júnior,Alexandre Humberto Andrei,D. N. da Silva Neto +11 more
TL;DR: In this article, the authors used the Platform for Reduction of Astronomical Images Automatically (PRAIA) to perform a digital coronography to minimize the influence of the scattered light of Uranus on the astrometric measurements and to determine accurate positions of the main satellites.

TL;DR: In this article, the authors derived results derived from four stellar occultations by the plutino object (208996) 2003 AZ(84), detected on 2011 January 8, 2012 February 3, 2013 December 2, and 2014 November 15 (multi-chord) and found that a Jacobi triaxial solution with semiaxes (470 +/- 20) x (383 +/- 10) x(245 +/- 8) km can better account for all the occultation observations.

TL;DR: In this article, the authors present results from a multi-chord Pluto stellar occultation observed on 2015 June 29 from New Zealand and Australia, which occurred only two weeks before the NASA New Horizons flyby of the Pluto system and serves as a useful comparison between ground-based and space results.
