In summary, the conversation discusses the need for theoretical isochrones to determine the age of clusters M15 and H+chi persei. The original plan was to use Seiss, but it is not currently available online. The individual then asks for alternative options and expresses interest in a potential Python script for data analysis. They also mention finding data on a website and their intention to create a script to streamline the process.

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!
 

FAQ: Where can I find theoretical isochrones?

What are theoretical isochrones?

Theoretical isochrones are a type of graph or diagram that show the predicted evolution of a group of stars with similar properties over time. They are commonly used in astronomy to estimate the age of star clusters and galaxies.

Where can I find theoretical isochrones?

Theoretical isochrones can be found in various scientific databases, such as the Astrophysics Data System (ADS) or the SIMBAD astronomical database. They may also be available on the websites of research institutions or universities.

How are theoretical isochrones created?

Theoretical isochrones are created using mathematical models and simulations, which take into account factors such as stellar mass, temperature, and composition. These models are constantly refined and updated as new data becomes available.

What can theoretical isochrones tell us?

Theoretical isochrones can provide valuable information about the properties and evolution of stars, such as their age, mass, and chemical composition. They can also help scientists understand the formation and evolution of galaxies and star clusters.

Are there any limitations to using theoretical isochrones?

Yes, there are limitations to using theoretical isochrones. They are based on models and simulations, which may not always accurately reflect the complexities of the real universe. Additionally, the accuracy of the isochrones depends on the quality and completeness of the data used in the models.
