Analysis
This paper investigates the star formation history in the Canis Major OB1/R1 Association, specifically focusing on a young stellar population near FZ CMa and the H II region Sh 2-295. The study aims to determine if this group is age-mixed and to characterize its physical properties, using spectroscopic and photometric data. The findings contribute to understanding the complex star formation processes in the region, including the potential influence of supernova events and the role of the H II region.
Key Takeaways
- •Identified 29 T Tauri stars (TTs) near Sh 2-295, including new members.
- •Found evidence of age-mixed stellar populations, with ages ranging from ~1 to 14 Myr.
- •Supports a scenario of multiple star-formation episodes, potentially triggered by the expansion of Sh 2-295.
- •Suggests limited influence of supernova events in this context.
Reference
“The equivalent width of the Li I absorption line suggests an age of $8.1^{+2.1}_{-3.8}$ Myr, while optical photometric data indicate stellar ages ranging from $\sim$1 to 14 Myr.”
