Because they are all made inside of stars.
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
Inside the sun, nuclear fusion creates helium nuclei from...a. oxygen nuclei. b. beryllium nuclei.c. carbon nuclei.d. hydrogen nuclei.The answer is d. hydrogen nuclei.
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 isthat one atomic nucleus combines with another to produce the nucleus of a new element.
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
Well, the fact that you said "trace elements" makes me think you probably don't mean hydrogen or helium, which are present in large amounts in stars.After those, the three most common elements would be oxygen, carbon ... and then it gets complicated. Most probably the third would be neon, but iron and nitrogen are also pretty common.
Carbon, oxygen, and iron nuclei are commonly found in stars because they are formed through nuclear fusion processes in the cores of stars. Carbon and oxygen are produced through fusion reactions in stars of medium mass, while iron is formed in the later stages of a star's life through various fusion processes. These elements are essential building blocks for heavier elements and are crucial for the evolution of stars.
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.

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.
Carbon is found in abundance in the sun, stars, comets and atmospheres
Carbon came first. Carbon is one of the most abundant elements in the universe and is formed in the core of stars through nuclear fusion reactions. Oxygen, on the other hand, is also formed in stars but typically in later stages of stellar evolution.
Hydrogen and helium are the most abundant gases in stars, with hydrogen being the most common element found in stars. Other gases present in stars include oxygen, carbon, neon, and iron in smaller quantities.

Carbon is a naturally occurring element that is formed through nuclear fusion in stars, primarily in the cores of massive stars through processes like the triple-alpha process. These processes involve the fusion of helium nuclei to produce carbon atoms.
I know that carbon plus oxygen equals iron and iron is what kills stars...
