I'm not sure if this is the best place to ask this but here goes, I am looking for a list of all stars within 1000 LY from earth, does anyone know where can i find such a list or database or catalog?
There is no such a list yet (a list with all the stars in 1000 ly from the Sun). Why? because we haven't reached completeness in the solar neighbourhood. Sure, in 1000 ly O- and B-type stars are all known (they are easy to spot with our technology) but for A-type the percentage of known objects drops. The vast majority of G, K and M stars inside that sphere are unknown as far as we can extrapolate the density of those in our inmediate vicinity and see that the count is lower than expected when you compare with the G, K and M type stars that we currently know in that radius from the Sun.
With our current understanding of the solar neighbourhood the stellar density is around 0.004 stars per cubic light-year. A sphere with 1000 ly in radius has a volume of 4.2 billion cubic light-years. Therefore your list should contain roughly 16.8 million stars. Let's see how many of those we know (also roughly). We are searching for stars that have a parallax value larger than 3.26 milliarcseconds. Doing a search in Simbad (the biggest centralized astronomical database in existence) we have 473.813 stars closer than 1000 ly.
This means that we currently have confirmed the 2,8% of the stellar population within 1000 ly from home (the vast majority are indeed cold stars since we see a lack of them in our databases when we go further). Besides that there are several problems with this estimate I've done.
1.- Not all known stars have parallax measurements (so maybe there are more that are inside the sphere but our query can't show them since no distance estimate has been archived in this case).
2.- Parallaxes have uncertainties and those uncertainties yield larger distance uncertainties if the star is closer to the edge of the 1000 ly sphere. So many of the stars we counted could be outside the sphere (a big part of them in fact), and also many that are outside the sphere could be inside in reality.
3.- Due to Lutz-Kelker bias many of these stars (even with those parallaxes) are actually farther away than we think.
Factoring all of this I guess that the known stars in that 1000 ly radius is below 3% of the stars that really inhabit the region.
Also I made a crude assumption taking the stellar density of the solar neighbourhood as constante in that sphere. A ball of 2000 ly in diameter is as large as to include the limits of the Galactic disk in the upper and lower part, and since the stellar density decreases (exponentially in general) there are less stars and thus maybe we have explored some percent more of the actual population. But as you see this is a tiny bit also and humanity still has to wait to have that list.
The fact that there is no completness in this 1000 ly around us can be illustrated by the low-right plot:
https://www.handprint.com/ASTRO/galaxy.html#NEstars
This is the count of stars (splitted in different temperature classes) that can be seen with the naked eye against distance. If we where able to see the all the objects (not caring about the sensitivity of our eyes or telescopes) the count should increase with the cube of the distance (since the volume cointaining stars increases with the cube of the radius of the sphere). Instead we see that kind of increasing trend only in the beggining and then the fact that farther away stars are dimmer makes us miss more and more with increasing distance so the effect of our inhability to spot dimmer objetcs start to break the power 3 behaviour. When we reach 300 parsec (more or less you 1000 ly) we count stars very sporadically while distance still increases, those are there but we can't see them. The change in behaviour of those curves marks where the completeness of our sample starts declining. This diagram is made for naked eye stars, but a similar diagram appears if you take into accound the capabilities of the most sensitive telescopes in the world (just that the point where the curves change behaviour are much farther away than in this case).
But, if you agree to have only the known stars in that radius and not all the existing stars then there are some tips you can follow:
1.- Start with
this list that spans the first 16.3 ly from the Sun. We believe that this has a 100% completeness (we expect no unkown stars in this region).
This list is very well curated and expand to the 21 light years. Between the wikipedia and this list there are probably missmatches (keep wikipedia list as the more rigorous if you see some that are missing in the other list).
2.- For beyond the 21 light years we have a very good list. Lists for all the stars within 100 ly (
Supergiants and subgiants,
B,
A,
F,
G,
K and
M lists). But bare in mind the completness here gets below the 20% of the actual expected stellar population (for each of those stars there are probably 4 more inside this 100 ly neighbourhood).
3.- Beyond 100 ly the only thing I can reccomend you is to go to
Simbad's query configuration and select ASCII format and click in file output, then save the configuration, go to the
criteria query tab and write plx>=3.26 as criteria. A file with the 473.813 stars closer than 1000 ly should be able for download. Then you should program some code (or do it manually until exhaustion) that sees if each star of the file has a van Leeuwen's Hipparcos reduction catalog (HIP) entry or a Tycho-Gaia astrometric solution entry (TGAS). In the case there is an entry in both you have to prioritize the data from TGAS over HIP. From parallax measurements you should get distances (the catalog issue is because Simbad doesn't put the best parallax measurements and is quite arbitrary, you have to search for them in HIP and TGAS since those are the best current references in distance measurements). Also keep in mind that the Hipparcos main catalogue is also non reliable because parallax measuremens were biased since there where attitude control errors and other problems in the mission (you always have to search for van Leeuwen's reduction). In principle don't worry, I talked to SpaceEngineer and in the next month I'm going to work very hard to make this possible (since all catalogue stars in SE come from hipparcos main catalogue and not from the currently accepted measurements). So if you wait I can do this work for you (but the completeness will be the ~3% expected, remember).
4.- You can wait until April of this year because
ESA's Gaia mission will release the biggest astrometric database of all time (with the most accurate parallax measurements archived to date) so you could have a more complete and accurate list. All stars with apparent magnitude of 20 or below would be visible and the survey would be complete (but since the very abundant G, K and M stars can have apparent magnitudes larger than that in the 1000 ly radius don't expect this to get the completeness in the 1000 ly sphere to the 100% in any way).
