Difference between S-type star and Technetium star

S-type star vs. Technetium star

An S-type star (or just S star) is a cool giant with approximately equal quantities of carbon and oxygen in its atmosphere. A technetium star, or more properly a Tc-rich star, is a star whose stellar spectrum contains absorption lines of the light radioactive metal technetium.

Similarities between S-type star and Technetium star

S-type star and Technetium star have 8 things in common (in Unionpedia): Asymptotic giant branch, Barium star, Carbon star, Dredge-up, Long-period variable star, R Geminorum, Stellar classification, Technetium.

Asymptotic giant branch

The asymptotic giant branch (AGB) is a region of the Hertzsprung–Russell diagram populated by evolved cool luminous stars.

Barium star

Barium stars are spectral class G to K giants, whose spectra indicate an overabundance of s-process elements by the presence of singly ionized barium, Ba II, at λ 455.4 nm.

Carbon star

A carbon star is typically an asymptotic giant branch star, a luminous red giant, whose atmosphere contains more carbon than oxygen; the two elements combine in the upper layers of the star, forming carbon monoxide, which consumes all the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a "sooty" atmosphere and a strikingly ruby red appearance.

Dredge-up

A dredge-up is a period in the evolution of a star where a surface convection zone extends down to the layers where material has undergone nuclear fusion.
