comment What is the deal with heat capacity?
By the way, I have just learned that when one references a paper of which one is an author (which is the case here), one should declare this fact.

@DepeHb In order to derive all thermodynamical quantities you need more information than just temperature as a function of pressure and volume. Normally, the additional equation gives entropy, also as a function of these variables although knowledge of the adiabats suffices (as a concrete example, for the ideal gas these are the well-known curves $pV^\gamma=constant$).

comment A change in the gravitational law
Not a direct answer but might be of interest. There are three cases of a central power law where all the orbits can be written down explicitly using elementary functions---inverse square, direct proportionality (Hooke's law) and the $\frac 1{r^3}$ of your question. In the latter case, the orbits are the so-called Cotes' spirals about which the internet is full of information. By the way, all three were known to Newton and are dealt with in his "Principia".

I might add that I have illustrated this method in answers to the following queries on this forum if you are looking for examples: 23644, 21965, 46759, 20843, 51683, 47841, 18510.
