Physical Parameters for RR Lyrae Stars in the SDSS Filter System
M. Catelan, G. I. Torrealba, C. Caceres +3
We present a calibration of the metallicity and physical parameters (temperature, luminosity, gravity, mass, radius) for RR Lyrae stars using the ugriz SDSS photometric system. Our…
The planetary nebula Abell 48 and its [WN] nucleus
David J. Frew, Ivan S. Bojicic, Q. A. Parker +6
We have conducted a detailed multi-wavelength study of the peculiar nebula Abell 48 and its central star. We classify the nucleus as a helium-rich, hydrogen-deficient star of type…
K 1-6: an asymmetric planetary nebula with a binary central star
David J. Frew, Jeff Stanger, Michael Fitzgerald +16
We present new imaging data and archival multiwavelength observations of the little studied emission nebula K 1-6 and its central star. Narrow-band images in H-alpha (+ [NII]) and…
