The CH fraction of carbon stars at high galactic latitudes

Goswami, A; Drisya, K; Shantikumar, N. S (Blackwell Publishing, 2010-02)

CH stars form a distinct class of objects with characteristic properties like iron deficiency, enrichment of carbon and overabundance of heavy elements. These properties can provide strong observational constraints for the ...
CH stars at high Galactic latitudes

Goswami, A (Blackwell Publishing, 2005-05)

Carbon-rich stars of Population II, such as CH stars, can provide direct information on the role of low- to intermediate-mass stars of the halo in early Galactic evolution. Thus accurate knowledge of the CH stellar population ...
A high-resolution spectral analysis of three carbon-enhanced metal-poor stars

Goswami, A; Aoki, W; Beers, T. C; Christlieb, N; Norris, J. E; Ryan, S. G; Tsangarides, S (Blackwell Publishing, 2006-09)

We present results of an analysis of high-resolution spectra obtained with the Subaru Telescope High Dispersion Spectrograph, of two Carbon-Enhanced Metal-Poor stars, HE 1305+0007 and HE 1152-0355, and of the classical CH ...
Low-resolution spectroscopy of high galactic latitude objects: a search for CH stars

Goswami, A; Bama, P; Shantikumar, N. S; Devassy, D (Astronomical Society of India, 2007-09)

Properties of CH stars like iron deficiency and enrichment of carbon and heavy elements can provide valuable inputs to our understanding of nucleosynthesis. In particular, these parameters provide strong observational ...
