The high-altitude, inner-disc, and chemically peculiar open cluster UBC 1052
Judit Donada, Laia Casamiquela, Friedrich Anders +8
Out of all the discovered open clusters (OCs) that are located in the inner part of the Galaxy, only a small fraction has been observed with high-resolution spectroscopy. An intrig…
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 (…
WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
M. I. Arnaudova, S. Das, D. J. B. Smith +62
We present a detailed study of the large-scale shock front in Stephan's Quintet, a byproduct of past and ongoing interactions. Using integral-field spectroscopy from the new Willia…
