Visual Magnitude of the BlueWalker 3 Satellite
Anthony Mallama, Richard E. Cole, Scott Harrington +1
Observations have been carried out in order to assess the optical characteristics of the BlueWalker 3 spacecraft which is the prototype for a new satellite constellation. The illum…
Milliarcsecond astrometry for the Galilean moons using stellar occultations
B. E. Morgado, A. R. Gomes-Júnior, F. Braga-Ribas +40
A stellar occultation occurs when a Solar System object passes in front of a star for an observer. This technique allows the determination of sizes and shapes of the occulting body…
Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
A multi-chord stellar occultation by the large trans-Neptunian object (174567) Varda
D. Souami, F. Braga-Ribas, B. Sicardy +41
We present results from the first recorded stellar occultation by the large trans-Neptunian object (174567) Varda that was observed on September 10, 2018. Varda belongs…
Light Curve Analysis of Ground-Based Data from Exoplanets Transit Database
F. Davoudi, S. J. Jafarzadeh, A. Poro +9
Photometric observations of exoplanet transits can be used to derive the orbital and physical parameters of an exoplanet. We analyzed several transit light curves of exoplanets tha…
Results of two multi-chord stellar occultations by dwarf planet (1) Ceres
A. R. Gomes-Júnior, B. L. Giacchini, F. Braga-Ribas +24
We report the results of two multi-chord stellar occultations by the dwarf planet (1) Ceres that were observed from Brazil on 2010 August 17, and from the USA on 2013 October 25. F…
