graduation at Física (Licenciatura) from Universidade Presbiteriana Mackenzie (1998), graduation at Física (Bacharelado) from Universidade Presbiteriana Mackenzie (1999), master's at Astronomy from Instituto Nacional de Pesquisas Espaciais (2003) and doctorate at Astronomy from Instituto Nacional de Pesquisas Espaciais (2007). Has experience in Physics, acting on the following subjects: sun: radio radiation, sun: magnetic fields, sun: fundamental parameters, atmosfera solar and sun: radius. (Source: Lattes Curriculum)
While in the optical, the solar surface shows the presence of dark sunspots (umbra and penumbra), at radio wavelengths those active regions can be brighter than the quiet Sun due to the local atmosphere temperature increase. This temperature increase at radio frequencies can be due to distinct emission mechanisms, usually bremsstrahlung and gyroresonance. Resent results showed that acti...
The project aims to study of magnetized features in the solar atmosphere. We can separate this regions in: a) the equatorial features which characterize the solar cycle (sunspots, active regions, plages, etc); b) the polar features that are correlated with the changes in the solar large scale magnetic fields (coronal holes, faculae, bright patches, etc). The study of these regions will...
We report the statistics of the number of active regions (NAR) observed at 17 GHz with the Nobeyama Radioheliograph between 1992, near the maximum of cycle 22, and 2013, that also includes the maximum of cycle 24, and we compare with other activity indexes. We find that NAR minima are shorter than those of the sunspot number (SSN) and radio flux at 10.7 cm (F10.7). This shorter NAR mini...
