Findings

Enhanced spectral analysis techniques for subdwarfs

Standardized method adopted by SD1000

Insights into subdwarf formation and atmospheric processes

Abstract

Separating the subdwarf populations may shed light on their formation history and give unique insights into the atmospheric processes that are thought to be responsible for their abundance diversity. Such a task requires complex and time consuming spectral analyses, which we started to tailor to our objectives a year ago. Here we report the updates that have been made over the past year and will be the standard method in SD1000.
