Association of radio polar cap brightening with bright patches and coronal holes
Caius L. Selhorst, Paulo J. A. Simoes, Alexandre J. Oliveira e Silva +3
Radio-bright regions near the solar poles are frequently observed in Nobeyama Radioheliograph (NoRH) maps at 17 GHz, and often in association with coronal holes. However, the origi…
The behavior of the spotless active regions during the solar minimum 23-24
Alexandre J. Oliveira e Silva, Caius L. Selhorst
In this work, we analysed the physical parameters of the spotless actives regions observed during solar minimum 23 - 24 (2007 - 2010). The study was based on radio maps at 17~GHz o…
Analysis Of Kepler-71 Activity Through Planetary Transit
Eber A. Gusmão, Caius L. Selhorst, Alexandre S. Oliveira
An exoplanet transiting in front of the disk of its parent star may hide a dark starspot causing a detectable change in the light curve, that allows to infer physical characteristi…
The influence of eclipses in the stellar radio emission
Caius L. Selhorst, Adriana Valio
Here we simulate the shape of a planetary transit observed at radio wavelengths. The simulations use a light curve of the K4 star HAT-P-11 and its hot Jupiter companion as proxy. F…
