Contributions are accepted from participants that presented invited plenary session reviews, contributed plenary session talks, and contributed posters. In addition, individual and collective contributions from (parallel) splinter sessions and contributions from the CS20 hack day are welcome. If you would like to submit a typical conference proceeding,  there are no formal page limits. For guidance we recommend you limit yourself to 4-8 pages for contributed talks and 10-15 pages for invited talks. Those wishing to submit a written conference proceeding are encouraged to format the document using the CS20 LaTeX template (available on https://github.com/CoolStars20/proceedings/releases/latest).  All such submissions should be made as PDFs and will be reviewed for content by the SOC and we may suggest edits. 

Submission of presentation slides from speakers and full posters are also encouraged. PDF versions of these documents are the preferred format for Zenodo contributions to permit the documents to be previewed in a web browser. For maximum impact, a written contribution may be provided with presentation slides and/or a poster to provide greater context. Contributions will be checked for the proper metadata. Instructions about how to prepare your contribution are available on http://coolstars20.cfa.harvard.edu/contributions.html
