Abstract:
The authors discuss recent observations obtained at the NTT and CFHT, aimed at finding and studying extragalactic AGB stars. An unexpected result of these observations has been the discovery of a population-II halo around a dwarf irregular galaxy. The authors discuss the carbon-star population of M31, and the goals of the NTT project.

Abstract:
The sample of PN in dwarf spheroidal galaxies has increased by a factor 3 following the discovery of these two PN in the Sagittarius dwarf. This provides a very useful sample of PN in unique low-metallicity environments and at known distances.

Abstract:
A subsample of six objects, which have the most disk-like gas distribution, was selected for long-slit spectroscopy at the ESO 3.6-m and ESO/MPI 2.2-m telescopes in order to map the gas velocity field. The photometric and kinematic results were then used to constrain the intrinsic shape and mass distribution of the host galaxy.

Abstract:
Observations indicate a scenario in which an under-energetic explosion took place in a low-mass progenitor. The weaker explosion provided less kinetic energy and a smaller amount of radioactive 56Ni which in turn provided less energy to the light curve than in most SN Ia.

Abstract:
The main characteristics of the COMIC detector, as measured during the acceptance tests in Meudon and during the commissioning run in November 1995 show that this camera, in conjunction with the adaptive optics system ADONIS, is fully adapted to imaging operation in 1 - 5 μm spectral band.
