A survey of diffuse interstellar bands in the Andromeda galaxy: optical spectroscopy of M31 OB stars
dust extinction – galaxies individual (M31) – galaxies ISM – ISM H ii regions – ISM
2010/11/10
We present the largest sample to-date of intermediate-resolution blue-to-red optical spectra of B-type supergiants in M31 and undertake the first survey of diffuse interstellar bands (DIBs) in this ga...
The highest-mass stars have the lowest frequency in the stellar IMF, and they are also the most easily observed stars. Thus, the counting statistics for OB stars provide important tests for the fundam...
Infrared properties of Active OB stars in the Magellanic Clouds from the Spitzer SAGE Survey
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present a study of the infrared properties of 4922 spectroscopically confirmed massive stars in the Large and Small Magellanic Clouds, focusing on the active OB star population. Besides OB stars, o...
