I am hoping someone out there has already done this.
I am looking to add recently located stars near earth.
I have an entry in nearstars.ssc for

Luhman 16 (WISE 1049−5319) {A&B}

But I am unsure of the accuracy, and would like to hear from someone who knows more than I do.

I am also looking for the numbers for

WISE 0855−0714
WISE 1506+7027

to add as well.

Names taken from

https://en.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs

I am sure there are others that need to be checked in addition to these.
Just hoping that someone has already done it, if not, I get to figure out more math, yay, not.

Janus,

The Wikipedia articles for those stars include links to the original discovery papers. Those papers include the information you're looking for.


The easiest way to find accurate information about most cataloged stars is to use the Simbad astronomical database service.

http://simbad.u-strasbg.fr/simbad/

Enter the star's name in the basic query field at http://simbad.u-strasbg.fr/simbad/sim-fbasic

Unfortunately, Simbad doesn't seem to have separate entries for most of the stars in the Wise catalog.

Sadly, when I put WISE 0855-0714 into the search at the link you provided, I get:

Identifier not found in the database : NAME wise 0855-0714

Such is life, all the more maths to do.

That's why I mentioned the links which are in the Wikipedia article.

The information you need is in the original discovery papers.

I am not doubting the information is there.
My problem is I am still wrapping my head around the way things are annotated.

I think and work primarily in degrees.
This whole hour, minute, second stuff drives me nuts.
Though I have used parallax in geometry and survey, but again, only in degrees.
P.S. I don't use telescopes, and if I did, I would simply make an auto gimble so it could locate stars for me based on GPS & GMT.

My interest is in stellar distribution.
Currently I am assembling a temperature map of nearby space.
Envision it this way.
In a camp fire the flame is not all one temperature, it changes as indicated by color.
What I am doing is assembling a 3D flame map using stars as temperature indicators.
A kind of temperature density mapping.
Or in terms of the person I am doing this for, picturing chaos to find the order and beauty within it.

I am working on a javascript page to convert between MHS & Degrees in my spare time.
I was simply hoping someone else had already checked for stars located or refined between the old forum shutdown, and this one starting up.

Since it does not appear so, I will keep working on it.

Have you downloaded the version of nearstars.stc that's on Sourceforge?

https://sourceforge.net/p/celestia/code/HEAD/tree/trunk/celestia/data/nearstars.stc

It's not current, but it's more recent than the version that's included with Celestia v1.6.1, so it might save you a little work.
