Red Supergiant Stars as Cosmic Abundance Probes. III. NLTE effects in J-band Magnesium lines
Maria Bergemann, Rolf-Peter Kudritzki, Zach Gazak +2
Non-LTE calculations for Mg I in red supergiant stellar atmospheres are presented to investigate the importance of non-LTE for the formation of Mg I lines in the NIR J-band. Recent…
<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…
Red Supergiant Stars as Cosmic Abundance Probes: II. NLTE Effects in J-band Silicon Lines
Maria Bergemann, Rolf-Peter Kudritzki, Matthias Wueurl +3
Medium resolution J-band spectroscopy of individual red supergiant stars is a promising tool to investigate the chemical composition of the young stellar population in star forming…
Red Supergiant Stars as Cosmic Abundance Probes: NLTE Effects in J-band Iron and Titanium Lines
Maria Bergemann, Rolf-Peter Kudritzki, Bertrand Plez +3
Detailed non-LTE calculations for red supergiant stars are presented to investigate the influence of NLTE on the formation of atomic iron and titanium lines in the J-band. With the…
