The Nature of the Hard-X-Ray Emitting Symbiotic Star RT Cru (2007)
Luna, G. J. M., Sokoloski, J. L.
We describe Chandra High-Energy Transmission Grating Spectrometer observations of RT Cru, the first of a new sub-class of symbiotic stars that appear to contain white dwarfs (WDs) capable of...
X-Ray Emitting Blast Wave from the Recurrent Nova RS Ophiuchi (2006)
Sokoloski, J. L., Luna, G. J. M., Mukai, K., Kenyon, Scott J.
Stellar explosions such as novae and supernovae produce most of the heavy elements in the Universe. Although the onset of novae from runaway thermonuclear fusion reactions on the surface of a white...
Nebular abundances of southern symbiotic stars (2005)
Luna, G. J. M., Costa, R. D. D.
We have calculated relative elemental abundances for a sample of 43 symbiotic stars. Helium abundances and the relative elemental abundances N/O, Ne/O, Ar/O were derived from new spectra collected in...
