Carbon isotope ratio in carbon stars of the galactic halo
Weanalysed CN red system (∼8000 Å) andC2 Swan system (∼4700 Å) to know carbon isotope ratios (12C/13C) for carbon stars in the Galactic halo, named CH stars. The isotope ratios are obtained for 6 CH stars by the curve-of-growth analysis of the isolated 12CN and 13CN lines. In this analysis, we compared directly 12CN and 13CN lines of similar intensities (iso-intensity method), and the resulting...
متن کاملThe 12 C / 13 C - ratio in cool carbon stars ?
We present observations of circumstellar millimetrewave 13CO line emission towards a sample of 20 cool carbon stars. Using a detailed radiative transfer model we estimate the circumstellar 12CO/13CO-ratios, which we believe accurately measure the important stellar 12C/13C-ratios. For those optically bright carbon stars where it is possible, our derived 12C/13Cratios are compared with the photos...
متن کاملThe APM Survey for Cool Carbon Stars in the Galactic Halo - II The Search for Dwarf Carbon Stars
We present proper motion measurements for carbon stars found during the APM Survey for Cool Carbon Stars in the Galactic Halo ( Totten & Irwin, 1998). Measurements are obtained using a combination of POSSI, POSSII and UKST survey plates supplemented where necessary by CCD frames taken at the Isaac Newton Telescope. We find no significant proper motion for any of the new APM colour-selected carb...
متن کاملVlt/uves Constraints on the Carbon Isotope Ratio
We analyzed the C i lines associated with the damped Lyα system observed at zabs = 1.15 in the spectrum of HE 0515–4414 to derive the C/C ratio. The spectrum was obtained by means of the UV-Visual Echelle Spectrograph (UVES) at the ESO Very Large Telescope (VLT). The obtained lower limit C/C > 80 (2σ C.L.) shows for the first time that the abundance of C in the extragalactic intervening clouds ...
متن کاملA sorghum (Sorghum bicolor) mutant with altered carbon isotope ratio
Recent efforts to engineer C4 photosynthetic traits into C3 plants such as rice demand an understanding of the genetic elements that enable C4 plants to outperform C3 plants. As a part of the C4 Rice Consortium's efforts to identify genes needed to support C4 photosynthesis, EMS mutagenized sorghum populations were generated and screened to identify genes that cause a loss of C4 function. Stabl...
