A Medium Resolution Near-Infrared Spectral Atlas of O and Early B Stars
M. M. Hanson, R. -P. Kudritzki, M. A. Kenworthy +2
We present intermediate resolution (R ~ 8,000 - 12,000) high signal-to-noise H- and K-band spectroscopy of a sample of 37 optically visible stars, ranging in spectral type from O3…
VLT K-band spectroscopy of massive stars deeply embedded in IRAS sources with UCHII colours
A. Bik, L. Kaper, M. M. Hanson +1
We have obtained high resolution (R = 10,000) K-band spectra of candidate young massive stars deeply embedded in (ultra-) compact HII regions (UCHIIs). In these clusters, three typ…
Detection of Near-IR CO Absorption Bands in R Coronae Borealis Stars
Emily D. Tenenbaum, Geoffrey C. Clayton, Martin Asplund +8
R Coronae Borealis (RCB) stars are hydrogen-deficient, carbon-rich pulsating post-AGB stars that experience massive irregular declines in brightness caused by circumstellar dust fo…
