Dancing with the Stars: Rotation periods and rotational velocities for the open clusters Messier 67 and Ruprecht 147

By analysing spectroscopic data from the GALAH Survey and photometric information from the K2 satellite mission, you will examine the relationship between photometric rotation periods and spectroscopic rotational velocities for stars in the open clusters M67 and Ruprech 147.

Rotation plays a crucial role in stellar evolution, influencing various stellar properties and phenomena. By analysing spectroscopic data from the GALAH Survey (Buder et al. 2021) and photometric information from the K2 satellite mission (Gruner et al. 2020 and 2023), you will examine the relationship between photometric rotation periods and spectroscopic rotational velocities for stars in the open clusters M67 and Ruprecht 147. These open clusters offer ideal test cases as they provide a population of stars with well-determined ages, metallicities, and distances. Even more intriguing is the possibility to investigate these properties for different types of stars that are member of these clusters: single stars on the main sequence, binary stars, blue stragglers, and main-sequence turn-off stars.

 

Research Objectives:

1. Conduct a literature review of the research topic

2. Match catalogues from spectroscopy and photometry

3. Analyse measurements for different types of stars and try to identify implications for identifying different stellar types in field stars
