In this paper, we follow the evolution of  SN 2017hpa with the Himalayan Chandra Telescope. 

Photometry and spectroscopy of the supernova revealed that the explosion is a normal supernova Ia. Observing a normal SN Ia allows measurement of the distance to its host galaxy. In the spectra we found strong presence of carbon. Unburned elements like carbon/oxygen provides insights into the supernova explosion. We attempted to fit the spectra with radiative transfer code to constrain the mass of carbon and found that carbon might be present in the inner layers of the supernova ejecta.  This hints towards an explosion mechanism that produces carbon up to a certain extent in the inner layers. A detailed modelling with TARDIS will be undertaken in the future.
