Help adding data for Stars

[Dan Dixon]

Here's the problem:

I don't have mass and diameter data for all of the nearest 50 stars (just the first 30 or so). This is a problem because when you open up the nearest 50 stars simulation in Universe Sandbox and view them in chart mode, about 15-20 of the stars default to a diameter of 1 km (which is totally wrong).

Perhaps a few of you might like to help collect this data.


Let's try an experiment:

Here's the spreadsheet with the data for the nearest 100 stars:
https://spreadsheets.google.com/ccc?key=0AoYA02Dt7PgRdHpPbEJONlFiUVZwOUEtMUFiOU11V0E&hl=en

I need your help adding mass, diameter, temperature, and rotation data (and the name if there is one).

You can search by the HIP # this is the Hipparcos Catalogue number or Gliese # to make sure you've got the right star.

The data you contribute will be available to everyone in the free version of Universe Sandbox 2, not just those who pay.

Here's the spreadsheet for the rest of the stars (101+) in the Universe Sandbox star database:

Guidelines

Don't make up data. If you can't find it, leave it blank.

If you're not sure what to put in the blank, just paste the webpage address, or type a note, into the field and I'll figure it out later.

Be sure to paste the website you found the data into the New Data Source column, this way we can verify that no one is making up numbers.

It's likely that humanity hasn't figured out the masses and diameters of all of these stars, some of this data may just not exist yet.

Well, I'm not going to help. It seems too hard.
GOOGLE DOCS! HOORAY! Still not doing it though.

[atomic7732]

I'll help, can I add other stars too? maybe?

Maybe in another version of the completed nearest stars, we can have the real extrasolar planets around them.

[Dan Dixon]

I'll help, can I add other stars too? maybe?

I only included the closest 100 stars in this list from the Stars.xml file found in the data folder where Universe Sandbox is installed.

Here's the rest of the stars... Feel free to add new stars to the bottom of this list:

Cool. I might as well join in the fun too.

[deoxy99]

Cool. I might as well join in the fun too.

Fun? You call this fun? It's boring.

[atomic7732]

It's awesome!

[deoxy99]

It's awesome!

Nuh-uh. It's not awesome.

[Naru523]

uh-huh. It's awesome.

Anyways, doing work on Gliese 581.

[atomic7732]

hehehe. Nice modifying. 

[deoxy99]

Doing this work on Gliese 581 is boring.

Take that Naru.

[Naru523]

Doing this work on Gliese 581 is epic.

Take that Deoxy.

[atomic7732]

I found a contradiction... Gliese 581 reads in the GLID "Gl 644 A"

[Naru523]

Yeah. In Stars 101+ Gliese 581 is the 121th star closest from the Sun which is suppose to be the 87th according to wikipedia.

[deoxy99]

Yeah. In Stars 101+ Gliese 581 is the 121th star closest from the Sun which is suppose to be the 87th according to wikipedia.

I guess with that quote modifying, we owned each other.

[Naru523]

Guess we can do that in another topic.
Or stop.
Hmm I think Im done with Gliese 581.

[Dan Dixon]

Yeah. In Stars 101+ Gliese 581 is the 121th star closest from the Sun which is suppose to be the 87th according to wikipedia.

Wikipedia may not be including the 2nd star in binary stars.

I found a contradiction... Gliese 581 reads in the GLID "Gl 644 A"

Just make a note (I've added a new column for this) and provide a link, if that makes sense and I'll check it out.

[Naru523]

Oh, I forgot. I thought you mean the system... Sorry for the coincedence.

[APODman]

Dan,

You know the name of the catalog that the stars are named "NN" ( like NN3877 ) ?

[deoxy99]

I helped.

[Dan Dixon]

Thanks everyone. This experiment is worked better than I expected!

You know the name of the catalog that the stars are named "NN" ( like NN3877 ) ?

They are Gliese #

I helped.

[APODman]

Dan I did not notice if you include the brown dwarf UGPS 0722-05 in this list of the 50 nearest stars.

This brown dwarf is at only 9 light years away!

More info here (and included phisical postional date):

Stars discovered in the last 2 years aren't included in the list.

I'll add this one for sure.

Do you know of any other newly discovered nearby stars?

[atomic7732]

Ummmm... I do, but don't know the name. It's a binary brown dwarf. It's a 2MASS... and it was in one of my podcasts... I'll try to find that!

[APODman]

Dan exist many, many brown dwarfs ( 2 Mass )with distances less than 50 light years.

Here a list that include than ( Table 5 ):

- http://iopscience.iop.org/1538-3881/126/5/2421/pdf/1538-3881_126_5_2421.pdf

In this paper are other close cool stars that are discovery between the year 2000 and 2002

A notable multiple system of Brown Dwarfs, at a distance less than 100 light years, are called DENIS-P J020529.0-115925, this is a triplet Brown Dwarf system !

Not sure if this helps but for each star , simbad include a bibliography section that lists papers that reference that star. These references might include the missing data.

Oh yay. I can bump things! Also this should become active again. (If it never become inactive.)
