A near-UV reconnaissance of metal-poor massive stars
Chris Evans, Wagner Marcolino, Jean-Claude Bouret +1
We use synthetic model spectra to investigate the potential of near-ultraviolet (3000-4050 Å) observations of massive O-type stars. We highlight the He I 3188 and He II 3203…
Physical properties of the first spectroscopically confirmed red supergiant stars in the Sculptor Group galaxy NGC 55
L. R. Patrick, C. J. Evans, B. Davies +5
We present K-band Multi-Object Spectrograph (KMOS) observations of 18 Red Supergiant (RSG) stars in the Sculptor Group galaxy NGC 55. Radial velocities are calculated and are shown…
Chemistry and Kinematics of Red Supergiant Stars in the Young Massive Cluster NGC 2100
L. R. Patrick, C. J. Evans, B. Davies +5
We have obtained K-band Multi-Object Spectrograph (KMOS) near-IR spectroscopy for 14 red supergiant stars (RSGs) in the young massive star cluster NGC 2100 in the Large Magellanic…
Red Supergiants as cosmic abundance probes: the first direct metallicity determination of NGC 4038 in the Antennae
C. Lardo, B. Davies, R-P. Kudritzki +5
We present a direct determination of the stellar metallicity in the close pair galaxy NGC~4038 (D = 20 Mpc) based on the quantitative analysis of moderate resolution KMOS/VLT spect…
Red Supergiant Stars as Cosmic Abundance Probes: KMOS Observations in NGC 6822
L. R. Patrick, C. J. Evans, B. Davies +5
We present near-IR spectroscopy of red supergiant (RSG) stars in NGC 6822, obtained with the new VLT-KMOS instrument. From comparisons with model spectra in the J-band we determine…
