In summary, the solar/stellar model is a framework used to understand the physical properties and behavior of stars. It involves studying their internal structure, energy production, and evolution over time. The main parameters used in this model include mass, temperature, luminosity, and chemical composition. By studying these parameters, scientists can gain a better understanding of the processes that drive stellar behavior and ultimately, the workings of the universe.

On a page such as this, from Bahcall's website, you can get links to the input parameters, and the publications describing the progressive refinements to the various standard solar models.

And http://www.ap.stmarys.ca/~guenther/Level01/solar/solar_history.html will give you a thumbnail sketch of the history behind their development, with references to the key original papers.

But does anyone have a good site which describes, at a physics undergraduate university level, an overview of the conservation laws used, the energy transport equations, and the limitations wrt main sequence stars (i.e. not degenerate stars, or supernovae). If such a site also notes the key differences between stellar models and gas giant planet models, so much the better!

Many thanks, in advance.

mmm are you only looking for websites? carroll&ostlie texbook is very sufficient in teaching an undergrad. ...it probably doesn't have the last thing you stated but I haven't read the planetary section.

These might not be at a high enough level, but they are a few of the best ones I have come across:

Thanks neurocomp2003 and Labguy.

Of course the best was last - the Vik Dhillon material is almost perfect :smile:

I saw this article today. Admittedly I am over my head here, but I found http://www.thesurfaceofthesun.com/
this stuff interesting. It deals with the hard surface of the sun.

Carroll and Ostlie is a good text.

What is a solar/stellar model?

A solar/stellar model is a theoretical representation of the structure and evolution of a star, including its internal composition, energy production, and physical parameters.

What are the parameters used in solar/stellar models?

The parameters used in solar/stellar models include mass, radius, luminosity, temperature, chemical composition, and age. These parameters are essential in predicting the behavior and characteristics of stars.

How are solar/stellar models created?

Solar/stellar models are created using a combination of physical laws, equations, and observational data. Complex computer simulations are also used to refine and validate these models.

Why are solar/stellar models important?

Solar/stellar models are important because they help us understand the fundamental processes that govern the behavior of stars. They also allow us to make predictions about the future evolution of stars and their potential impact on the universe.

What are some applications of solar/stellar models?

Solar/stellar models have various applications, including predicting the behavior of stars at different stages of their evolution, understanding the formation of planetary systems, and studying the effects of stellar activity on planetary atmospheres. They also provide crucial insights for space missions and astronomical observations.
