    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

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
