Kepler Managed to Explain Supernovae


The explosion that takes place at the end of the life for huge stars is an event that occurs very often. However, despite this thing, scientists have not managed to witness this event very often. The intensity of a supernovae is so big that is supposed to outshine the entire galaxy.

A special kind of explosion was the Fast-Evolving Luminous Transients (FELTs). These very rarely spot, because they only appear in the sky for a few days. However, now we finally have some more data about them thanks to Kepler.

Kepler explained exploding stars

NASA’s Kepler Space Telescope has managed to bring a lot of important data about the planets. This time it appeared that the satellite managed to bring some important data about Fast-Evolving Lumious Transients. Thanks to Kepler, astronomers realised that a FELT is “… a new kind of supernova that gets a brief turbo boost in brightness from its surroundings.”

A statement was released based on Kepler’s findings. According to the astronomers, “Kepler’s ability to precisely sample sudden changes in starlight has allowed astronomers to quickly arrive at this model for explaining FELTs, and rule out alternative explanations.”

It appears that Kepler managed to bring all the necessary measurements that were needed in order to “record more details of the FELT event”. “We collected an awesome light curve. We were able to constrain the mechanism and the properties of the blast. We could exclude alternate theories and arrive at the dense-shell model explanation. This is a new way for massive stars to die and distribute material back into space.

With Kepler, we are now really able to connect the models with the data. Kepler just makes all the difference here. When I first saw the Kepler data, and realized how short this transient is, my jaw dropped. I said, “Oh wow!” declared Astronomer Armin Rest of the Space Telescope Science Institute in Baltimore, Maryland.
