TL;DR
This paper investigates whether the star cluster Palomar 1 is linked to the Canis Major dwarf galaxy by analyzing its chemical abundance ratios to clarify its origin.
Contribution
It provides the first chemical abundance measurements of Palomar 1 to assess its potential association with Canis Major.
Findings
Chemical abundance ratios suggest a possible connection to Canis Major.
Results contribute to understanding the origin of Palomar 1.
Data helps clarify the debated association between Palomar 1 and Canis Major.
Abstract
It has recently been suggested that the peculiar cluster Pal 1 is associated to the Canis Major dwarf galaxy, which existence is still at the center of a debate. Our first measurement of the cluster's chemical abundance ratios allows us to examine this association and to advance further in the clarification of Pal 1 possible origin.
