The website: http://www.atlasoftheuniverse.com/startype.html
was about what I was looking for and will find that info very useful.
Thanks very much

I have been unable to find any data or formula's on how long red giant type stars last
other than a few million years!One would suppose that it is a function of its original mass
and chemical composition.
Any ideas...
On the exoplanet database they have a value which I am not familiar with, can anyone
help me understand what value they are displaying represents?
Luminosity ?
" compared to solar luminosity?
Does LOG mean they performed a logarithm?
see attached...
Well for now I am back to the Nasa Exoplanet database due to its simplicity.
I am able to search for star data if I go to Modify field .They have a convert results to CSV format function which I can than import to MYSQL and work with that data as I see fit.
I performed a star search which...
Yes that looks very good, I just have to brush up on my SQL a bit .
The Nasa database was a little easier to use but I believe this one is more complete
and I can produce very precise reports .
I will follow up a bit later as to my progress...
I am looking for a On line or downloadable stellar highly detailed database.
Nasa had a excellent one but seemed to remove it from (NASA Star and Exoplanet Database (NStED).
Wiki has lots of detail on there website but its star by star basis.I want to analyse
large batches of stellar data...
I have been finding formula's for just about everything about stars and
was wondering if core and surface temperature has a formula as well?
Its 2,771,043 for the Sun as an example.( core / surface)kelvin.
Thanks...
