Red Supergiants as Cosmic Abundance Probes: The Sculptor Galaxy NGC 300
J. Zachary Gazak, Rolf Kudritzki, Chris Evans +9
We present a quantitative spectroscopic study of twenty-seven red supergiants in the Sculptor Galaxy NGC 300. J-band spectra were obtained using KMOS on the VLT and studied with st…
Red Supergiants as Cosmic Abundance Probes: The Magellanic Clouds
Ben Davies, Rolf-Peter Kudritzki, Zach Gazak +4
Red Supergiants (RSGs) are cool (~4000K), highly luminous stars (L - 10^5 Lsun), and are among the brightest near-infrared (NIR) sources in star-forming galaxies. This makes them p…
A Direct Stellar Metallicity Determination in the Disk of the Maser Galaxy NGC4258
Rolf-Peter Kudritzki, Miguel A. Urbaneja, J. Zachary Gazak +4
We present the first direct determination of a stellar metallicity in the spiral galaxy NGC4258 (D=7.6 Mpc) based on the quantitative analysis of a low-resolution (~5 AE) Keck LRIS…
