Simbad aladin2/27/2023 ![]() ![]() The WISE ID below the image contains the object coordinates, like this example WISE ID: J131701.32-022615.8, you can convert this information in this way 13:17:01.32 and -02:26:15.8 and search in the surveys with the position data.Ī new version of Aladin is now available here: SIMBAD server is down, reports an internal error, if you know how to search in VIZIER this is the link: See the "new face" on NED! You can test the new interface here: Now is easier to find information if you know the object name. It's better in SDSS or WISE colored images □ If you know the name of the object but not its coordinates, then enter its name instead of coordinates. I want to add the blog post by that also explains why we can't see disks, planets or moons in the interfaz images. ![]() Great That it's the most frequent question. I hope that this will help at least some of you. In case that SIMBAD server is down, then you can insert WISE ID instead of coordinates. On VizieR you can find informations about all DD objects, but keep in mind that nothing is perfect and you can find various informations that are contradictory. Size of Red Circle is 10.5 arcseconds radius Size of Disk Detective image is 60 arcseconds across Those are the links that you can sometimes find on SIMBAD, like here:Įnter the coordinates and radius, then go to the result page. ![]() If there isn't any info on SIMBAD, you can use VizieR. The easiest way to find out all available informations Now you just have to zoom in and click on SIMBAD or NED link. You should see something like this:Īfter that, load Simbad and NED (It may take a while, depending on the size of the displayed area). You find the coordinates after you click on the button “More Info on SIMBAD”.Īfter you run the Aladin, then insert the coordinates and press ENTER key. Now it's properly listed as Possible AGN on SIMBAD It's an example of why not to rely only on SIMBAD. I chose this object because SIMBAD says it's a star, but NED says that it's a galaxy. It's simple actually and you don't need to be an expert.Īladin - Interactive sky atlas. I'll show you here how to find informations about objects other than through SIMBAD. You can find here: that SIMBAD isn't perfect and doesn't contain informations about every object in the sky. If you want to know whether it's a star, galaxy or something else, then SIMBAD isn't the only way. I decided to create this some sort of "simple guide" for those who would like to know some informations about the object which you classify. it could be interesting.Want to be a black belt classifier? Check out these tips. If somebody sees an error by me or has another program to try this visualization on GSC data. At the moment I did not find an explanation for this behaviour. Note about Stellarium: even if the program finds the star by name, the Ra,Dec shown on the top left are slightly different from those on Simbad. Note for neophytes: depending on your position and current Stellarium time you could have the need to disable the landscape (G) to see the star below the horizon. (on the right of Sadr (gamma Cyg), below Delta Cyg, above NGC 6819) Zoom appropriately to see that faint dot ! Type the star name: GSC 03144-00002 and enter to have Stellarium move the view to the star. Hit K to stop the clock and hit F3 (find). Now for even more fun, eyepiece simulation and so on: open Stellarium and ensure you have downloaded at least catalog 7 to see these star magnitudes. In the middle of the image you will notice the red text "Planet ?" click on that with your mouse and you will get a list of object names on the bottom (the 6 planets and the star overlap on the image because they have been assigned the same rough coordinates). With this third URL you will get a Java applet downloading DSS imagery with more options for you to play with:īe patient, it will take some time to download, ask you about the certificate, about the network access auth, download the image, etc etc.but IMHO it's worth the wait The star exactly in the middle of the image, with two dimmer on its left and right is Kepler-11. On Simbad you can obtain more precise coordinates and information: "Kepler-11 is a G dwarf star with Kepler magnitude Kp = 13.7, visual magnitude V = 14.2 mag, and celestial coordinates RA = 19h 48m 27.62s, Dec = +41° 54' 32.9" alternate designations used in catalogs are KIC 6541920 and KOI-157." ![]()
