Today was the last day and wrap-up for the 2019 SB Gaia Sprint. It was quite a week! A few highlights from the wrap-up (for me, very subjective, not fair or complete) were: Schwab Abrahams (Berkeley) showed that stars which are flagged in certain ways in the Gaia data are reliably variable stars, by looking at TESS light curves. Coronado (MPIA) showed that stars with small orbital-action differences tend to also have small element-abundance differences. Brown (Leiden) and others worked on making “Gold” samples in Gaia data that make it easy for people to look at or follow up spectroscopically. Mateu (UdelaR) improved her catalog of, and meta-data on, stellar streams in the halo. El Badry (Berkeley) convincingly showed us that there is an excess of very precisely equal-mass binary stars even at very large separations. Widrow (Queen's) showed first attempts at trying to perform a regression that can be used to infer the Galactic bar density from velocity fields. Hunt (Toronto) showed velocity and density maps of a simulated disk that look very much like the features that Eilers (MPIA) and I see in the data! And Laporte (UVic) showed a great movie of the data in the phase spiral (The Snail!) that shows its beautiful and informative dependence on azimuthal action (or really vertical frequency I think!). It was a great week with great people doing great things in a great location. I'm exhausted! The wrap-up slides are available here.
