Trevor David (Flatiron) is looking at the estimation of stellar ages, maybe inspired by his beautiful paper from 2020. Today I met with him and Megan Bedell (Flatiron) to look at making age estimates out of observed surface abundances. We discussed the possibility that we could build a latent-variable model in which each star has a latent state, which generates the observed age indicators and abundances. We went through some conceptual math and left it to David to look at implementations. This fits into a long-term goal I have of unifying all age indicators!
