The habitability of the exoplanet has a strong dependence on the stellar activity of the host star. M-dwarf stars constitute a large fraction of the stellar population, therefore they are of primary interest in searching potentially habitable exoplanets. It is easier to detect planets around low-mass stars since they have effectively smaller radii and low temperatures due to which we can easily detect planet transits. The stellar flares from the host star may play a crucial role in triggering prebiotic chemistry on the exoplanet, whereas large frequency flares and CMEs would lead to atmospheric erosion and ozone depletion. The stellar flares sometimes are associated with Coronal Mass Ejections, which may directly impact the exoplanetary atmospheres and affect habitability. Here, we present a case - study of the flaring activity of an M-dwarf star and its impact on its orbiting exoplanet in the habitable zone. We utilized the light-curve data from TESS. We used the AltaiPony python-based package to identify flares. We further analyze and quantify the flare activity to understand its possible impact on the exoplanet environment around the habitable zone.
