Dust around R Coronae Borealis stars: II. Infrared emission features in a H-poor environment
D. A. Garcia-Hernandez, N. Kameswara Rao, D. L. Lambert
Residual Spitzer/IRS spectra for a sample of 31 R Coronae Borealis (RCB) stars are presented and discussed in terms of narrow emission features superimposed on the quasi-blackbody…
The changing nebula around the hot R Coronae Borealis star DY Centauri
N. Kameswara Rao, D. L. Lambert, D. A. Garcia-Hernandez +1
Among the distinguishing characteristics of the remarkable hot R Coronae Borealis star DY Cen, which was recently found to be a spectroscopic binary, is the presence of nebular for…
High-resolution optical spectroscopy of DY Cen: diffuse interstellar bands in a proto-fullerene circumstellar environment?
D. A. Garcia-Hernandez, N. Kameswara Rao, David L. Lambert
We search high-resolution and high-quality VLT/UVES optical spectra of the hot R Coronae Borealis (RCB) star DY Cen for electronic transitions of the C60 molecule and diffuse inter…
High-resolution spectroscopy of the R Coronae Borealis and Other Hydrogen Deficient Stars
N. Kameswara Rao, David L. Lambert
High-resolution spectroscopy is a very important tool for studying stellar physics, perhaps, particularly so for such enigmatic objects like the R Coronae Borealis and related Hydr…
High-resolution spectroscopy of the R Coronae Borealis Star V Coronae Australis
N. Kameswara Rao, David L. Lambert
Optical high-resolution spectra of the R Coronae Borealis star V CrA at light maximum and during minimum light arediscussed. Abundance analysis confirms previous results showing th…
R Coronae Borealis Stars at Minimum Light -- UW Cen
N. Kameswara Rao, B. E. Reddy, D. L. Lambert
Two high-resolution optical spectra of the R Coronae Borealis star UW Cen in decline are discussed. A spectrum from mid-1992 when the star had faded by three magnitudes shows just…
