SUMMARY

The discussion centers on the need for theoretical isochrones for age determination of star clusters M15 and H+chi Persei. The user initially sought data from the Seiss website but found it unavailable. Alternatives mentioned include using data from the STETSI database, which requires additional processing to extract relevant color indices. The user plans to create a Python script to streamline this data manipulation process.

PREREQUISITES
  • Understanding of theoretical isochrones in astrophysics
  • Familiarity with color index calculations
  • Basic knowledge of Python programming
  • Experience with data extraction from online databases
NEXT STEPS
  • Explore the STETSI database for theoretical isochrones
  • Learn how to calculate color indices from stellar data
  • Develop a Python script for data processing and visualization
  • Research alternative sources for theoretical isochrones in astrophysics
USEFUL FOR

Astronomy students, astrophysicists, and researchers working on stellar evolution and cluster age determination will benefit from this discussion.

I am currently doing a 2nd year lab report and need some theoretical isochrones to work out the age of some clusters, M15 and H+chi persei (Double Cluster).

I was going to use Seiss: http://www-astro.ulb.ac.be/~siess/server/iso.html

But it doesn't seem to be online :(

What alternatives are there?

Any help would be greatly appreciated.

I found the data here http://stev.oapd.inaf.it/cgi-bin/cmd it is rather laborious to strip the data calculate the relevant colour index and plot it so I might make a python script to do it.

I hope this will be of use to anyone else who has the same problem and comes across this thread via the search function.
 
I am certainly intersted in that Python script!
