Gaia Sprints

2017 Heidelberg Gaia Sprint

This page preserves the history from the 2017 Heidelberg Gaia Sprint, which took place 2017 July 17 through 21 at the Internationales Wissenschaftsforum Heidelberg.

Results

Before and during the meeting, we kept jointly edited 2017 HD Gaia Sprint Running Notes that gathered information about homework solutions, intended projects, and breakouts.

On the first day, all participants presented a slide from the jointly edited 2017 HD Gaia Sprint Pitch Slides to introduce themselves, their skills, expertise, and their ideas for the week.

On the last day, the wrap up was given from a jointly edited set of 2017 HD Gaia Sprint Wrap-up Slides, which summarize the accomplishments made throughout the week.

The 2017 HD Gaia Sprint has in part resulted in the following publications:

• WISE2150-7520AB: A very low mass, wide co-moving brown dwarf system discovered through the citizen science project Backyard Worlds: Planet 9, Faherty, Jacqueline K. et al.
