Where can I find a comprehensive online database for stellar data analysis?

In summary, the user is looking for a highly detailed database of stellar data that can be downloaded or accessed online. They mention that NASA used to have a good one but it has been removed. They have found some information on Wiki and the website Simbad, but they are looking for a database that can handle large batches of data at once. The user mentions an interest in Gyrochronology and rotational velocity data. They are pointed towards the Sloan Digital Sky Survey and Vizier as potential sources. They also mention using a CSV file and MySQL to work with the data.

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 at once.

the website simbad is ok but lacks complete info.

I may begin some work in Gyrochronology but need rotational velocity.

Thanks very much
Bob

robertrej, welcome to Physics Forums!

Is what you are seeking here at the Sloan Digital Sky Survey?

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.


Thanks
Bob

"Gyrochronology"

I thought I'd kept up with the field, but that's a new one to me ! Many Thanks for teaching me a new word and a fascinating technique !

Vizier is a good source of all kinds of astronomical data. It includes a large number of databases, including SDSS.

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 produced 56,000 results.( mass = .4 -2.4).

CSV = comma separated data file format.
MYSQL -Oracle: open source database program.

Have a good week
Bob
