Mixing processes during the evolution of red giants with moderate metal deficiencies : the role of molecular-weight barriers

Corinne Charbonnel, Jeffery A. Brown, George Wallerstein

We have assembled accurate abundance data for Li, C, and N as well as the 12C/13C ratio for five field giants with [Fe/H]=-0.6 including Arcturus and two stars in the globular clus…

Spectral properties of galaxies in the Stromlo-APM redshift survey: clues on the local star-forming galaxies

Laurence Tresse, Steve J. Maddox, Jon Loveday

We analyse emission-line properties of the bj-selected Stromlo-APM spectra (<z> = 0.05). Because this is a representative sample, we can study the global spectral properties of the…

COMPTEL Observations of 3C 279 during the first 4 Years of the CGRO-Mission

W. Collmar, J. J. Blom, K. Bennett +6

The COMPTEL experiment aboard the Compton Gamma-Ray Observatory (CGRO) has observed the gamma-ray blazar 3C 279 several times between April 1991 and September 1995. This paper repo…

COMPTEL observations of the quasar PKS 0528+134 during the first 3.5 years of the CGRO mission

W. Collmar, K. Bennett, H. Bloemen +9

The COMPTEL observations of the blazar-type quasar PKS 0528+134 in the energy range 0.75 MeV to 30 MeV carried out between April 1991 and September 1994 have been analyzed. During…

Lithium and binarity in M67

D. Barrado y Navascues, J. R. Stauffer, S. Balachandran

A study of the lithium abundances in binaries of the old open cluster M67 is presented. Abundances were estimated using curves of growth and equivalent widths of the LiI6707.8 Å do…

Photo-evaporation of clumps in Planetary Nebulae

Garrelt Mellema, Alejandro C. Raga, Jorge Canto +4

We study the evolution of dense neutral clumps located in the outer parts of planetary nebulae. These clumps will be photo-ionized by the ionizing radiation from the central star a…
