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…
<3D> NLTE line formation in the atmospheres of red supergiants
Maria Bergemann, Rolf P. Kudritzki, Ben Davies +3
Red supergiants with their enormous brightness at J-band are ideal probes of cosmic chemical composition. It is therefore crucial to have realistic models of radiative transfer in…
The temperatures of Red Supergiants
Ben Davies, Rolf-Peter Kudritzki, Bertrand Plez +6
We present a re-appraisal of the temperatures of Red Supergiants (RSGs) using their optical and near-infrared spectral energy distributions (SEDs). We have obtained data of a sampl…
