Isochrone fitting to the open cluster M67 in the era of Gaia and improved model physics
Claudia Reyes, Dennis Stello, Marc Hon +3
The Gaia mission has provided highly accurate observations that have significantly reduced the scatter in the colour-magnitude diagrams of open clusters. As a result of the improve…
