El paso del geocentrismo al heliocentrismo
(Universidad Autónoma de Occidente, 2004-01)
En la presente exposición se quiere trazar de manera muy gruesa las grandes directrices que llevan de la concepción geocéntrica del universo a la heliocéntrica sacrificando hechos históricos —sin duda importantes— para una ...
Do geocentrismo à gravitação universal: proposta e implementação de uma sequência didática para o ensino médio
(Universidade Federal de São CarlosUFSCarPrograma de Mestrado Nacional Profissional em Ensino de Física - PROFISCâmpus São Carlos, 2016-08-18)
This work is formed by the development and implementation of an Educational Product, which by means of a didactic sequence (DS), aimed to address geocentrism, heliocentrism and universal gravitation topics in a less classical ...
A hands-on exploration of the retrograde motion of Mars as seen from the Earth
(IOP Publishing, 2013-07)
In this paper, we propose a set of activities based on the use of a celestial simulator to gain insights into the retrograde motion of Mars as seen from the Earth. These activities provide a useful link between the ...
Discovery and Mass Measurements of a Cold, 10 Earth Mass Planet and Its Host Star
(2011)
We present the discovery and mass measurement of the cold, low-mass planet MOA-2009-BLG-266Lb, performed with the gravitational microlensing method. This planet has a mass of mp = 10.4 ± 1.7 M⊕ and orbits a star of mass M = ...

Whiting 1: Confirmation of its accretion by the Milky Way
(EDP Sciences, 2017)
We investigate the association of Whiting 1 with the Sagittarius tidal stream by obtaining radial velocities for a sample of 101 stars observed with VIMOS. Our results reveal the presence of a component of the Sagittarius ...
Fundamental parameters of six neglected old open clusters
(BLACKWELL, 2006-09-21)
In this paper, we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by ...
