Abstract Younger and fully convective stars are much more active than our Sun, producing many superflares. Here we estimate the impact of the superflares UV radiation on living organisms on the surface of orbiting planets in the habitable zone of the star. For this we study two active stars, Kepler-96 (solar type) and TRAPPIST-1 (M dwarf). Kepler-96, with an age of 2.4 Gyr, is at the same stage of the Sun when the first multicellular organisms appeared on Earth. The biological impact of super… 
The impact of stellar activity on orbiting planets
Stellar activity manifests itself in the form of surface features such as spots and faculae, and flares and mass ejections from its atmosphere. Flares and superflares have been detected from active

Superflare Ultraviolet Impact on Kepler-96 System: A Glimpse of Habitability When the Ozone Layer First Formed on Earth.
Considering the increase in the UV flux by the strongest superflare emission, Escherichia coli and Deinococcus radiodurans could survive on the surface of the planet only if there was an ozone layer present on the planet atmosphere, but could escape from the hazardous UV effects at a depth of 28 and 12 m below the ocean surface, respectively.
The effect of a strong stellar flare on the atmospheric chemistry of an earth-like planet orbiting an M dwarf.
The results indicate that the UV radiation emitted during the flare does not produce a significant change in the ozone column depth of the planet, and flares may not present a direct hazard for life on the surface of an orbiting habitable planet.
UV surface habitability of the TRAPPIST-1 system
With the discovery of rocky planets in the temperate habitable zone (HZ) of the close-by cool star TRAPPIST-1 the question of whether such planets could harbour life arises. Habitable planets around
Statistical properties of superflares on solar-type stars based on 1-min cadence data
We searched for superflares on solar-type stars using Kepler data with 1-min sampling in order to detect superflares with a short duration. We found 187 superflares on 23 solar-type stars whose
Habitat of early life: Solar X‐ray and UV radiation at Earth's surface 4–3.5 billion years ago
[1] Solar X-ray and UV radiation (0.1–320 nm) received at Earth's surface is an important aspect of the circumstances under which life formed on Earth. The quantity that is received depends on two
Solar irradiance variability during the October 2003 solar storm period
The extraordinary solar storms between 18 October 2003 and 5 November 2003 include over 140 flares, primarily from two different large sunspot groups. There were 11 large X‐class flares during this
The Great Flare of 1985 April 12 on AD Leonis
Photometric and spectroscopic observations covering the wavelength range 1200-8000 A are presented for a giant flare on the M dwarf star AD Leo. The flare radiated more than 10 34 ergs in this
Frequent Flaring in the TRAPPIST-1 System-Unsuited for Life?
We analyze the K2 light curve of the TRAPPIST-1 system. The Fourier analysis of the data suggests P rot = 3.295 ± 0.003 days. The light curve shows several flares, of which we analyzed 42 events with
Sensitivity of selected bacterial species to UV radiation
It seems that the possession of pigments had no important effect in the sensitivity of R. sphaeroides to UV radiation, and E. coli was the most sensitive bacterium tested.
