    Database Stellar
AI Thread Summary
A user is seeking a comprehensive online or downloadable database for detailed stellar data analysis, noting that NASA's previous database has been removed. They mention that while the SIMBAD database is useful, it lacks complete information. The Sloan Digital Sky Survey (SDSS) is suggested as a more complete alternative, although it requires some SQL knowledge. Another user recommends Vizier as a good source for various astronomical data, including SDSS. The discussion highlights the importance of accessible databases for conducting large-scale analyses in fields like gyrochronology.

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

"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

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
