THE MARSEILLE OBSERVATORY H SURVEY OF THE SOUTHERN GALACTIC PLANE AND MAGELLANIC CLOUDS

The Survey of the Magellanic clouds

Due to their close distance, the Magellanic Clouds are also observed with the same instrument. The kinematical map of the fast moving nebulae with their full extension (stellar wind driven bubbles and supernovae remnants) was obtained, and the energetic balance of the nebulae was established. Indeed, the spectral information interpretation and the flux calibration allow the determination of the expansion velocity and electron density of the objects. For this purpose the SMC was completely covered (30 fields) while for the LMC about 40 fields were observed, in both the H and [OIII] lines.

Concerning the SMC a catalogue and the kinematics of the HII regions were established, the rotation curve was determined (Le Coarer et al., 1993) and several SNR were observed. More specifically, two new SNR candidates were identified inside the HII complex N19. About the LMC, the results are more specific to individual regions: detection of stellar wind driven bubbles inside the nebulae N120A, N11B (Rosado et al., 1996) and N59 (Rosado et al., 1997), detection of SNR candidates inside N103A (Ambroccio-Cruz et al., 1997) and N186E, and study of probable sequential stellar formation inside N11, N120, N105, and the supergiant bubbles LMC1 and LMC4.
