Accelerated post-AGB evolution, initial-final mass relations, and the star-formation history of the Galactic bulge
K. Gesicki, A. A. Zijlstra, M. Hajduk +1
We study the star-formation history of the Galactic bulge, as derived from the age distribution of the central stars of planetary nebulae that belong to this stellar population. Th…
Carbon enrichment of the evolved stars in the Sagittarius dwarf spheroidal
Iain McDonald, Jennifer R. White, Albert A. Zijlstra +5
We present spectra of 1142 colour-selected stars in the direction of the Sagittarius Dwarf Spheroidal (Sgr dSph) galaxy, of which 1058 were taken with VLT/FLAMES multi-object spect…
Disk evaporation in a planetary nebula
K. Gesicki, A. A. Zijlstra, C. Szyszka +3
We study the Galactic bulge planetary nebula M 2-29 (for which a 3-year eclipse event of the central star has been attributed to a dust disk) using HST imaging and VLT spectroscopy…
Detection of the Central Star of the Planetary Nebula NGC 6302
C. Szyszka, J. R. Walsh, Albert A. Zijlstra +1
NGC 6302 is one of the highest ionization planetary nebulae known and shows emission from species with ionization potential >300eV. The temperature of the central star must be >200…
