Solar Nebula Oxygen Isotopes 26Al Nearby Supernova
2011/1/10
Injection of material from a core-collapse supernova into the solar system's already-formed disk is one proposed mechanism for producing the short-lived radionuclides, such as 26Al and 41Ca, inferred ...

Spectroscopic observations dwarf spirals galaxies
2011/1/13
The oxygen abundances for four dwarf spiral galaxies have been determined using long-slit spectroscopy. The abundances of these galaxies have not previously reported in the literature. Several HII reg...
