Revisiting the near infrared Calcium triplet as metallicity indicator
M. Navabi, R. Carrera, N. E. D. Noël +3
The near-infrared Calcium II Triplet (CaT), around 850nm, is a key metallicity indicator for red giant stars. We present a revised [Fe/H] calibration as a function of CaT line stre…

Outside-In Evolution with a Twist: Metallicity Gradients and Asymmetries in the SMC
M. Navabi, R. Carrera, N. E. D. Noël +1
Taking advantage of the near-infrared calcium triplet lines, we determine metallicities for a sample of more than 3,500 red giant stars in the field of the Small Magellanic Cloud (…
