My References

As we know, reference is a citation is the mention of a foreign text, idea or phrase, sends the reader to the source from which the information was obtained and is present in the bibliographical reference. References to authors in the text should be made as follows: Author's name, comma, year of publication. By this way, I have put here where I extract all the data and how I have known that what I have obtained is definite too.

The firts one has relation with exoplanets' part. So is where I have been able to compare it.

Teh second reference, has relation with supernovas and where I compare that all the elements that is had found in the supernova are sure ones.
