Our view of our cosmic neighbourhood is getting more and more detailed. With the Hubble Space Telescope, it became possible to resolve many members of the Local Group into individual stars, a legacy that will soon be continued by its successor, the James Webb Space Telescope. In the meantime, our Galaxy is being surveyed in unprecedented detail by the Gaia satellite and wide-field imaging surveys are continuing to discover its faintest companion galaxies. In the not too distant future, the E-ELT will push the study of resolved stellar populations towards local volume galaxies.
Spectroscopic follow-up is indispensable for the interpretation of the photometric and astrometric data, therefore the advent of powerful spectrographs marked a cornerstone for the study of resolved stellar populations. On small scales, integral-field spectrographs such as KMOS or MUSE allow us to target individual stars even in crowded stellar fields nowadays. On larger scales, the next generation of multi-object spectrographs (including 4MOST or the proposed MOSAIC instrument) will soon revolutionise our capabilities for wide-field spectroscopic surveys.
The purpose of this splinter is to bring together the German community working on optical/NIR spectroscopy of resolved stellar populations. We plan to discuss the current status of the field, identify open questions, and exchange about new ideas with current and future observing facilities. The topics we aim to cover include (but are not exclusive to)
We plan to have a healthy mix of contributed and invited talks. Graduate students are especially encouraged to apply.
