Chemical composition and circumstellar shells of carbon stars - Any obvious relations?
Published online by Cambridge University Press: 04 August 2017
Extract
Evidence for circumstellar absorption around the warm N-type carbon star TX Piscium was found in a high-resolution IUE spectrum by Eriksson et al. (1986). This investigation also included the search, with a positive result, for CO J=1−0 emission from the circumstellar shell. From the Mn I absorption and CO emission a column density of about 1020–1022 H atoms per cm2 was estimated, as well as a mass loss rate around 10−7–10−6 M per year.
