Original research by young twinkle students (ORBYTS): Ephemeris refinement of transiting exoplanets
(Oxford University Press, 2021-07)
We report follow-up observations of transiting exoplanets that have either large uncertainties (>10 min) in their transit times or have not been observed for over 3 yr. A fully robotic ground-based telescope network, ...
Posição de objetos centauros e transnetunianos através de ocultações estelares na era Gaia
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Física e AstronomiaUTFPR, 2018-07-06)
Most of the small bodies of the outer Solar System, with the exception of Pluto, were discovered after 1992. It is believed that due to their distance to the Sun, these objects can have information about the Solar System’s ...
La puesta en escena de la efeméride provincial de Andrés Guacurarí y Artigas. Aportes desde una mirada semiótica-comunicacionalThe provincial ephemeris of Andrés Guacurarí y Artigas. Contributions from a semioticcommunicational perspective
(Universidad Nacional del Litoral. Facultad de Humanidades y Ciencias. Departamento de Letras, 2017-12)
La conmemoración de las efemérides en la escuela nos ofrece uno de los espacios fundamentales en los que se narra los sentidos de la nación. En la actualidad observamos que en la provincia de Misiones se implementaron ...
TraMoS: V. Updated ephemeris and multi-epoch monitoring of the hot Jupiters WASP-18Ab, WASP-19b, and WASP-77Ab(star)
(EDP Sciences, 2020)
We present 22 new transit observations of the exoplanets WASP-18Ab, WASP-19b, and WASP-77Ab, from the Transit Monitoring in the South project. We simultaneously model our newly collected transit light curves with archival ...
TERMS Photometry of Known Transiting Exoplanets
(2011)
The Transit Ephemeris Refinement and Monitoring Survey (TERMS) conducts radial velocity and photometric monitoring of known exoplanets in order to refine planetary orbits and predictions of possible transit times. This ...
The Impact on Geographic Location Accuracy due to Different Satellite Orbit Ephemerides

Lyapunov-based Low-energy Low-thrust Transfers to the Moon
This paper investigates the numerical computation of low-fuel low-thrust Earth-Moon transfers in a full ephemeris model incorporating the gravitational influence of the Sun, the Moon and all planets of the solar system ...
A Search for the Transit of HD 168443b: Improved Orbital Parameters and Photometry
(2011)
The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. In this work we present the search for transits of HD 168443b, a massive planet ...
