Is There A Needle In The Haystack? Using Python To Narrow Down The Search For Life I
summary
Argues that life-search shrinks dramatically by selecting stars in long-lived core-rotation zones rather than every disk star, using the Gaia catalog (∼1 billion stars) to pick candidates and Python tools to test them. Implements a simple crawler, Jupyter notebooks and galpy orbit integration to rewind stellar orbits, animates results, and finds that stars in corotation avoid frequent spiral-arm crossings so the searchable sky becomes a far smaller, tractable region.
