Using the technique of spectroscopy, scientists can deduce the temperature and chemical composition of material around a star, even if they cannot see the disc itself.
We need to know exactly the thermonuclear processes that produce energy, and the mass and chemical composition of a model star.
Vega is an important star in astronomy in more than one way: the fifth brightest star of the night sky, one of the three "beauties of summer" (with Deneb and Altair) which forms a large triangle at ...

In general, main sequence stars have chemical compositions similar to that of the Sun. The higher the mass of the main sequence star, the greater its diameter and the higher its surface temperature.
Once they are known, we can calculate the abundances of the atoms from the strengths of the absorption lines and therefore calculate the chemical composition of the outer part of a star.
"We have analysed in great detail the chemical composition of stars in three star-clusters and shown that each cluster presents a high level of homogeneity and a very distinctive chemical signature," ...
