Identificação de ciclos magnéticos em estrelas do tipo solar observadas pelo satélite Kepler
(Universidade Presbiteriana Mackenzie, 2017-02-06)
The stellar magnetic field plays a crucial role in the star internal mechanisms, as well as in the interactions with its environment. The study of starspots gives us information about the magnetic field of the star, and ...
Raio solar em frequências subterahertz e sua relação com a atividade solar
(Universidade Presbiteriana Mackenzie, 2017-08-01)
The Sun emits radiation at several wavelengths of the electromagnetic spectrum. In the optical band, the solar radius is 696,000 km and this is what defines the photosphere, the visible surface of the Sun. However, as ...
Serviço local de periodograma em GPU para detecção de trânsitos planetários
(Universidade Presbiteriana Mackenzie, 2017-06-13)
Understanding other stellar systems is crucial to a better knowledge of the Solar System, as is the study of extrasolar planets orbiting the habitable zone of their host star central to the understanding of the conditions ...
Rotação diferencial de estrelas pelos métodos de trânsito e máxima entropia
(Universidade Presbiteriana Mackenzie, 2019-08-27)
Modulations in the light curve of a star are caused by the presence of spots and faculae in its surface. During a planetary transit, spots might be covered by the planet creating a bump in the transit light curve. The ...
