| Abstract: |
Despite the great progress made in the last decade, the study of very massive stars remains hampered by the lack of statistics and only a few hundred stars with Minit ≥ 30 MSolar are known in our Galaxy. Low resolution, slitless spectral images were obtained at the Loiano Observatory in the wavelength window 3300-6420 Å, in order to identify in extragalactic objects targets displaying the most prominent features that characterise the spectrum of bright hot stars, WR and Luminous Blue Variables (LBV), and of nebular regions as well. We present the results with the well studied galaxy M 101, where the previously known H II regions with WR star signatures are easily identified. |
