A new algorithm for optimizing the wavelength coverage for spectroscopic studies: Spectral Wavelength Optimization Code (SWOC)

G. R. Ruchti, S. Feltzing, K. Lind +7

The past decade and a half has seen the design and execution of several ground-based spectroscopic surveys, both Galactic and Extra-galactic. Additionally, new surveys are being de…

Stellar science from a blue wavelength range - A possible design for the blue arm of 4MOST

C. J. Hansen, H. -G. Ludwig, W. Seifert +12

From stellar spectra, a variety of physical properties of stars can be derived. In particular, the chemical composition of stellar atmospheres can be inferred from absorption line…

A K-band spectral mini-survey of Galactic B[e] stars

A. Liermann, O. Schnurr, M. Kraus +3

We present a mini-survey of Galactic B[e] stars mainly undertaken with the Large Binocular Telescope (LBT). B[e] stars show morphological features with hydrogen emission lines and…

Discovery of a new Wolf-Rayet star using SAGE-LMC

V. V. Gvaramadze, A. -N. Chené, A. Y. Kniazev +1

We report the first-ever discovery of an extragalactic Wolf-Rayet (WR)star with Spitzer. A new WR star in the Large Magellanic Cloud (LMC) was revealed via detection of its circums…

A Systematic Search for Corotating Interaction Regions in Apparently Single Galactic WR Stars. I. Characterizing the Variability

N. St-Louis, A. -N. Chene, O. Schnurr +1

We present the results of a systematic search for large-scale spectroscopic variability in apparently single Wolf-Rayet stars brighter than ~12.5. In this first paper we characteri…

VLT/SINFONI time-resolved spectroscopy of the central, luminous, H-rich WN stars of R136

O. Schnurr, A. -N. Chene, J. Casoli +2

Using the Very Large Telescope's Spectrograph for INtegral Field Observation in the Near-Infrared (VLT/SINFONI), we have obtained repeated AO-assisted, NIR spectroscopy of the six…
