| Abstract: |
Traditionally, the initial final mass relationship has been proved using open clusters, but these
relatively young populations cannot constrain the low mass end. In this work we show how wide binaries
comprised by two white dwarfs can be used to constrain this problem by measuring their cooling ages
from optical spectra. The best constraints come from wide binaries containing white dwarfs with very
different cooling ages (i.e. very different masses). The cooling age difference between the two white
dwarfs provides an upper limit for the progenitor mass of the younger object in the system. We will show our results
based in our search of white dwarf binaries in Sloan Digital Sky Survey (SDSS) DR9. |
