SBS 1150+599A: an extremely oxygen-poor planetary nebula in the Galactic halo? [PDF]

open access: yes, 2001
We report results of a spectrophotometric study of SBS 1150+599A and discuss the nature of this object based upon our data. Our study shows that SBS 1150+599A is most probably a planetary nebula located in the Galactic halo and not a cataclysmic variable

Dust in an extremely metal-poor galaxy: mid-infrared observations of SBS 0335-052 [PDF]

open access: yes, 1998
The metal deficient (Z = Z_sun/41) Blue Compact Dwarf Galaxy (BCD) SBS 0335-052 was observed with ISOCAM between 5 and 17 mic. With a L_12mic/L_B ratio of 2.15, the galaxy is unexpectedly bright in the mid-infrared for such a low-metallicity object.
