MUSE 3D spectroscopy of BA-type supergiants in NGC 300
Gemma González-Torà, Miguel A. Urbaneja, Norbert Przybilla +4
We present the results obtained using spectroscopic data taken with the intermediateresolution Multi Unit Spectroscopic Explorer (MUSE) of B and A-type supergiants and bright giant…
The metallicity and distance of NGC 2403 from blue supergiants
Fabio Bresolin, Rolf-Peter Kudritzki, Miguel A. Urbaneja
We present the first quantitative spectral analysis of blue supergiant stars in the nearby galaxy NGC 2403. Out of a sample of 47 targets observed with the LRIS spectrograph at the…
A spectroscopic study of blue supergiant stars in Local Group spiral galaxies: Andromeda and Triangulum
Cheng Liu, Rolf-Peter Kudritzki, Gang Zhao +4
Low-resolution LAMOST and Keck spectra of blue supergiant stars distributed over the disks of the Local Group spiral galaxies M 31 and M 33 are analyzed to determine stellar effect…
The nature of the Cygnus extreme B-supergiant 2MASS J20395358+4222505
A. Herrero, S. R. Berlanas, A. Gil de Paz +19
2MASS J20395358+4222505 is an obscured early B supergiant near the massive OB star association Cyg OB2. Despite its bright infrared magnitude (K=5.82) it has remained largely…
MUSE crowded field 3D spectroscopy in NGC 300 II. Quantitative spectroscopy of BA-type supergiants
Gemma González-Torà, Miguel A. Urbaneja, Norbert Przybilla +4
A quantitative spectral analysis of BA-type supergiants and bright giants in an inner spiral arm region of the nearby spiral galaxy NGC 300 is presented, based on observations with…
