You will see how much the accepted stellar evolution models do not account for the basics.
Thermochemistry is the study of the energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling. Thermochemistry focuses on these energy changes, particularly on the system's energy exchange with its surroundings. Thermochemistry is useful in predicting reactant and product quantities throughout the course of a given reaction. In combination with entropy determinations, it is also used to predict whether a reaction is spontaneous or non-spontaneous, favorable or unfavorable. Endothermic reactions absorb heat. Exothermic reactions release heat. Thermochemistry coalesces the concepts of thermodynamics with the concept of energy in the form of chemical bonds. The subject commonly includes calculations of such quantities as heat capacity, heat of combustion, heat of formation, enthalpy, entropy, free energy, and calories.
These concepts are what star science is all about. The "experts" are fucking clueless.

The Kepler-discovered Systems with Tightly-packed Inner Planets (STIPs), typically with several planets of Earth to super-Earth masses on well-aligned, sub-AU orbits may host the most common type of planets, including habitable planets, in the Galaxy. They pose a great challenge for planet formation theories, which fall into two broad classes: (1) formation further out followed by inward migration; (2) formation in situ, in the very inner regions of the protoplanetary disk.
The actual categories are such:
1. Rocky, gaseous, plasmatic bodies as mutually exclusive, and only plasmatic ones evolving.
2. Rocky, gaseous, plasmatic bodies as not mutually exclusive, with plasmatic and gaseous ones evolving towards becoming rocky.
They pose a great challenge to planet formation theories... well duh!!

Disk winds? Does a basic astrophysical student need to tell these people that outer space is vacuum? They just place winds wherever they want! The only "winds" are from solar wind ripping away the atmospheres of other objects and the other objects' atmospheres themselves. There are no "disk winds", and they definitely do not cause an entire 6 sextillion ton object to migrate (Earth). Its just outright ridiculous.
