[Webnucleo-public] Polytrope Tool vs Standard Solar Model (BP2004)

[Lonnie Cumberland]

Greetings All,

I have only recently come across the Polytrope Tool and want to compare
various data against the Standard Solar Model (BP2004) data.

In particular, the standard solar model lists various data fields like:


astro-ph/0402114

Columns in the Standard Model table (below) represent:

1)  Mass fraction in units of the solar mass
2)  Radius of the zone in units of one solar radius
3)  Temperature in units of deg (K)
4)  Density in units of g/cm^3
5)  Pressure in units of dyn/cm^2
6)  Luminosity fraction in units of the solar luminosity
7)  X(^1H): the hydrogen mass fraction
8)  X(^4He): the helium 4 mass fraction
9)  X(^3He): the helium 3 mass fraction
10) X(^12C): the carbon 12 mass fraction
11) X(^14N): the nitrogen 14 mass fraction
12) X(^16O): the oxygen 16 mass fraction

The Table begins here.

since I have only just started using the Polytrope Tool, (which I think is
VERY good by the way), I was not sure of the out data from the tool as it
did not seem to compare to the tables in the BP2004 data file.

I am wondering if someone might be able to tell me if I am missing some
scaling or something?

Thanks and have a great day,
