Tombaugh 2: The first open cluster with a significant abundance spread or embedded in a cold stellar stream?

Frinchaboy, P M; Marino, Anna; Villanova, S; Carraro, G; Majewski, S; Geisler, D

Description

We present new high-resolution spectroscopy from which we derive abundances and radial velocities for stars in the field of the open cluster Tombaugh 2 (To2), which has been suggested to be one of a group of clusters previously identified with the Galactic Anticenter Stellar Structure (GASS) (also known as the Monoceros stream). Using Very Large Telescope/Fibre Large Array Multi-Element Spectrograph (VLT/FLAMES) with the Ultra-Violet and Visible Echelle Spectrograph (UVES) and GIRAFFE...[Show more]
