The enigma of the oldest `nova': the central star and nebula of CK Vul
M. Hajduk, Albert A. Zijlstra, P. A. M. van Hoof +9
CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova, or a very late thermal pulse object. Following its eruption in AD 1670, the star remained visib…
Planetary Nebulae as Probes of the Chemical Evolution of Dynamically Hot Systems
Michael G. Richer, Marshall L. McCall
The measurement of chemical abundances in planetary nebulae in nearby galaxies is now relatively straightforward. The challenge is to use these chemical abundances to infer the che…
Optical Line profile variability of the B1+neutron star binary system LS I+65 010 = 2S 0114+650
Gloria Koenigsberger, Gabriela Canalizo, Anabel Arrieta +2
We present high resolution spectroscopic observations of the massive X-ray binary system LS I+65 010=2S 0114+650 in the optical wavelength region. A correlation between equivalent…
The Red Stellar Contents of Three Selected Fields of The Local Group Dwarf Irregular Galaxy IC1613
J. Borissova, L. Georgiev, R. Kurtev +4
We present a moderately-deep JK photometry for three selected areas of the dwarf irregular galaxy IC1613. The color-magnitude diagrams contain a mixture of red supergiants, asympto…
The chemical evolution of dynamically hot galaxies
Michael G. Richer, Marshall L. McCall, Grazyna Stasinska
We investigate the chemical properties of M32, the bulges of M31 and the Milky Way, and the dwarf spheroidal galaxies NGC 205, NGC 185, Sagittarius, and Fornax using previously pub…
