Peering Through the Dust: Exploring the Metal-Poor Open Cluster Trumpler 5 in Infrared

This study used infrared spectroscopy to analyze seven red giant stars in the dust-obscured open cluster Trumpler 5 (Tr5). The team developed a new method to estimate stellar gravity and measured abundances for over 20 elements. Their findings confirmed Tr5’s metal-poor nature, estimated its age at 2.5 billion years, and enhanced understanding of stellar evolution in dusty regions of the Milky Way.
