Found 2 biggies. There is extended_sources but not: sources

        point_sources alt unresolved_sources.

> Can we find appropriate mathematical

No ontology here. But, if you just want a taxonomy, there is one in the MathML specification. I attach it for you.

, physical
There are a bunch of physical ontologies from JPL that I used a bit, but   I think one has to pick and choose from it. http://sweet.jpl.nasa.gov/ontology/
And there is the one that I worked on.

  and/or chemical

Sweet has elements in substance.owl.
http://ontology.dumontierlab.com/chemistry-primitive-1.0.owl just a list of the elements here:
http://ontology.dumontierlab.com/element-primitive

Don't forget Geometry

There is geometry in SWEET.
But, I like this one:

Lyman_alpha_absorption_system broader absorption_line_system RT "quasars" "Lyman_alpha_forest"

Trouble already. Rob Olling, is in my office, and he insists that
L_dwarfs and T_dwarfs are simply not stars. These are brown_dwarfs which are not stars. For the sake of simplicity, I can see leaving such things as stars; including neutron stars, white dwarfs etc. But, is this going to be acceptable to the IAU? The argument is beginning to filter out into the hallway.

dark_matter but Dark_Energy?

Rob objects here too. Red Clump stars are metal rich helium burning stars and therefore a kind of horizontal branch stars. The term is red_clump.
