Superflare UV flashes impact on Kepler-96 system: a glimpse of habitability when the ozone layer first formed on Earth

Understand

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 Earth's atmosphere due to micro-organisms living in the ocean.
• We present the analysis of superflares seen on the transit lightcurves of Kepler-96b.
• The model used here simulates the planetary transit in a flaring star.
