Using planetary transits to estimate magnetic cycles lengths in Kepler stars
Raissa Estrela, Adriana Valio
Observations of various solar-type stars along decades revealed that they can have magnetic cycles, just like our Sun. An investigation of the relation between their cycle length a…
Superflare UV flashes impact on Kepler-96 system: a glimpse of habitability when the ozone layer first formed on Earth
Raissa Estrela, Adriana Valio
Kepler-96 is an active solar-type star harbouring a Super-Earth planet in close orbit. Its age of 2.3 Gyr is the same as the Sun when there was a considerable increase of oxygen in…
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…
Activity and rotation of Kepler-17
A. Valio, R. Estrela, Y. Netto +2
Magnetic activity on stars manifests itself in the form of dark spots on the stellar surface, that cause modulation of a few percent in the light curve of the star as it rotates. W…
