Stellar Populations of Kinematically Decoupled Cores in E/S0 Galaxies
By mapping both the stellar kinematics and absorption-line strengths in a two-dimensional area, integral-field spectroscopy allows us to directly associate...
The history of the Milky Way is recorded in its stars, but dissecting stellar populations is not a straighforward process. Key information is gained by...
Stellar Velocity Profiles and Line-Strengths out to Four Effective Radii in the Early-Type Galaxy NGC 3379
We describe a new technique to measure stellar kinematics and line-strengths at large radii in nearby galaxies. Using the integral-field spectrograph SAURON as...
Stellar wind from Of stars from infrared and radio observations
Infrared and radio observations of the Of stars HD 108, HD 14947, HD 16691, HD 47129 are reported. They confirm the presence of thermal stellar wind emission...
Strong winds from massive stars are a topic of interest to a wide range of astrophysical fields. In High-Mass X-ray Binaries the presence of an accreting...
In previous papers we have published preliminary results on the stellar oxygen-abundance gradient in M33 by using B-type supergiants. In the present study, we...
