Fluorine in R Coronae Borealis and Extreme Helium Stars
Gajendra Pandey, David L. Lambert, N. Kameswara Rao
Neutral fluorine lines are identified in the optical spectra of several R Coronae Borealis stars (RCBs) at maximum light. These lines provide the first measurement of the fluorine…
Fluorine in R Coronae Borealis Stars
Gajendra Pandey, David L. Lambert, N. Kameswara Rao
Neutral fluorine (F I) lines are identified in the optical spectra of several R Coronae Borealis stars (RCBs) at maximum light. These lines provide the first measurement of the flu…
Discovery of Fluorine in Cool Extreme Helium Stars
Gajendra Pandey
Neutral fluorine (F I) lines are identified in the optical spectra of cool EHe stars. These are the first identification of F I lines in a star's spectrum, and provide the first me…
Abundance analysis of cool extreme helium star: LSS 3378
Gajendra Pandey, Bacham E. Reddy
Abundance analysis of the cool extreme helium (EHe) star LSS 3378 is presented. The abundance analysis is done using LTE line formation and LTE model atmospheres constructed for EH…
An analysis of ultraviolet spectra of Extreme Helium Stars and new clues to their origins
Gajendra Pandey, David L. Lambert, C. Simon Jeffery +1
Abundances of about 18 elements including the heavy elements Y and Zr are determined from Hubble Space Telescope Space Telescope Imaging Spectrograph ultraviolet spectra of seven e…
The R Coronae Borealis stars - carbon abundances from forbidden carbon lines
Gajendra Pandey, David L. Lambert, N. Kameswara Rao +3
Spectra of several R Coronae Borealis (RCB) stars at maximum light were examined for the [C I] 9850 A and 8727 A absorption lines. The 9850 A line is variously blended with a Fe II…
