Atmospheres of Red Supergiant Stars. II. The M 2 Supergiant Star Betelgeuse
Publications of the Astronomical Society of Japan, 1976Abstract The possibility of applying model atmospheres for the interpretation of observed spectral energy distributions is examined in the case of Betelgeuse as an example. The effect of atomic line absorptions is taken into account by an empirical line-blocking analysis, while the line-blanketing effect due to molecular absorption is ...

The Temperatures of Red Supergiants: how cool are the coolest massive stars?
EAS Publications Series, 2013We have re-appraised the temperatures of Red Supergiants (RSGs) in the Magellanic Clouds, by studying their spectral energy distributions (SEDs) from 400-2500 nm using VLT+XSHOOTER, in conjunction with MARCS model atmospheres. We determine temperatures using 3 methods: from model fits to the TiO bands in the optical; from model fits to the SED using ...

Remarks on red giant and supergiant stars
2008The preceeding review paper by Hollis Johnson and these remarks summarize portions of a half-day meeting held immediately prior to the Fifth Cool Stars Workshop. This special session was held in order to allow the astronomers interested in problems related to the atmospheres and evolution of red giant and supergiant stars to share ideas on selected ...
