    Weighing Stars from Birth to Death: How to Determine Stellar Masses?
    from 19 Nov 2018 through 23 Nov 2018

 

Accurate and precise stellar masses, and by implication ages, are not only critical for Galactic archaeology but also for many other fields in astrophysics, from exoplanets studies to the understanding of advanced stages of stellar evolution. The main aim of this workshop is to bring together participants from several fields to discuss and compare the different mass determination techniques used for different types of stars, confront the strengths and weaknesses of all methods, and establish the required level of precision for a wide range of applications.

In addition to review and contributed talks before noon, we foresee two short “challenge talks” intended to formulate the needs of a specific mass determination method and the accompanying requirements for the input from other fields. The challenge talks are also aimed at triggering discussions and guiding work to be done by the participants in several groups in the afternoons. This work in small groups will have two main goals. On the one hand, we will collect a number of benchmark stars with precise mass determinations to be used as reference stars for a number of ongoing and upcoming surveys. On the other hand, we will start working on a review paper on the different methods available for mass determinations, highlighting strengths and weaknesses, with the ultimate goal of presenting the state-of-the-art and a roadmap for the next decade.
