Context. Very little is known about the polarimetric properties of CH stars and carbon-enhanced metal-poor (CEMP) stars, although many of these objects have been studied in detail both photometrically and spectroscopically. Aims. ...

Chemical composition of metal-poor stars are crucial to develop an understanding of the nature of the earliest stars formed in the universe, the nucleosynthesis events associated with them, as well as, to redefine the ...

CH stars are known to show enhanced abundances of carbon and heavy s-process elements. They are metal-deficient population II objects. Their luminosities indicate that they are mostly giants; hence, the observed enhanced ...
