  1. “Open science is the movement to make scientific research, data

    and dissemination accessible to all levels of an inquiring society, amateur or professional.” – Wikipedia
  2. Fraction of papers on the arXiv in 2015, by journal:

    MNRAS 90% 87% ApJ Icarus 19% Source: https://gist.github.com/barentsen/99c9d5fab8fefdd46a1e
  3. Using proprietary data as a reward system bears a significant

    cost … we are slowing down science by 1 to 5+ years; we are reducing the impact of limited-lifetime missions; we are blocking early-career researchers from showing their skills & talents; we are reducing diversity by reserving facilities for rich institutions; we are discouraging the public from active participation in science.
  4. K2 data shows significant systematics due to targets drifting 1-2px

    across the detector Vanderburg et al. 2015
  5. Faced by a limited lifetime and new systematics, K2 took

    the open approach: – No proprietary data: all those with the right skills and talents can benefit from the data. – Competition: we fund different groups to do the same science ($10k-$150k grants). – Community products: large, funded K2 programs are required to release value-added data and software.
  6. K2’s early productivity outperforms Kepler’s! Kepler exoplanet papers (first two

    years) K2 exoplanet papers (first two years) 42 48 K2 literature features more unique authors & more unique institutions.
  7. Call to action Question the use of restrictive policies and

    proprietary periods; they are harmful to science and to early-career astronomers. Question the notion that we can’t have more than one paper on the same data or discovery. Don’t fear your colleagues, fear losing public support for science.
