As helium builds up in the sun's core, other fusion reactions occur. Over time, two or more helium nuclei can fuse, forming beryllium. Another helium nucleus can fuse with a beryllium nucleus, forming carbon, and so on. Stars the size of the sun do not contain enough energy to produce elements heavier than oxygen. But larger stars do.
The Sun isn't making those elements; what of them exist are the result of production in other stars. Currently, the Sun makes only helium, which, although it's really a gas, was named "sun metal."
Edit: The Sun will make heavier elements later, but only up to oxygen. The way stars like the Sun make carbon and oxygen is by nuclear fusion. This is the same way they make helium from hydrogen. This process of making elements is called nucleosynthesis. The details can get quite technical, but the basic idea is
that one atomic nucleus combines with another to produce the nucleus of a new element.
Stars are predominantly made up of hydrogen and helium, with trace amounts of other elements such as oxygen, carbon, and nitrogen. These elements undergo nuclear fusion reactions in the core of the star to produce energy and light.
Elements present in a star just before it forms a supernova would include hydrogen, helium, carbon, oxygen, and iron. The star undergoes nuclear fusion to produce heavier elements in its core, leading to the buildup of iron which triggers the supernova explosion.
Carbon and oxygen are the two main elements that make up a white dwarf star. These elements are the end products of nuclear fusion in the core of the star before it exhausted its nuclear fuel and collapsed to form a white dwarf.
If a star system has planets, the availability of oxygen on a given planet is a complicated process. If the planet is of the correct size and in the ecosphere of the star, the production of oxygen will occur through the existence of plant life that will convert carbon dioxide into oxygen. In a primordial planet like an earth, oxygen is not going to be an element that is naturally occurring. The compound carbon dioxide is. It takes plant life to produce an atmoshpere that will sustain animal life.The odds of this happening in a given star system are low, but possible.
The Polaris star is primarily composed of hydrogen and helium, with trace amounts of other elements such as carbon, nitrogen, and oxygen. Its composition is similar to that of other stars in the Milky Way galaxy.
It is not specifically those elements which "produce stars". Whatever elements happen to be around clump together, through gravity, and form the star.
Mostly in planetary nebulae where a star that was big enough to produce oxygen when it exploded is.
Antares is a red supergiant star composed mostly of hydrogen and helium, with traces of heavier elements like carbon, oxygen, and nitrogen. Its outer layers are cooler, which give the star its distinctive red color.

Formation of the carbon atomic nucleus requires a three way collision of helium nuclei (alpha particles within the core of a giant or supergiant star. These three helium nuclei are converted into carbon by means of the triple-alpha process. [See link] This carbon is then scattered into space when the star explodes as a supernova. For smaller stars the Bethe-Weizsäcker-cycle or CNO cycle (carbon-nitrogen-oxygen) [See link] , is one of two sets of fusion reactions by which stars convert hydrogen to helium. In the CNO cycle, four protons fuse using carbon, nitrogen and oxygen isotopes as a catalyst to produce one alpha particle, two positrons and two electron neutrinos. The carbon, nitrogen, and oxygen isotopes are in effect one nucleus that goes through a number of transformations in an endless loop.

These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
As our sun (or a similar star) exhausts its hydrogen supply, it begins to fuse helium to create carbon. The reaction is sometimes called the tripple-alpha process. Wikipedia has particulars and a link is provided.
The Polaris star is primarily composed of hydrogen and helium, with trace amounts of other elements such as carbon, nitrogen, and oxygen. Its composition is similar to that of other stars in the Milky Way galaxy.
The final elements fused in a star of the mass of our Sun are Oxygen then Carbon. Therefore a white dwarf core could be regarded as a solid, gigantic diamond.
