In the space between galaxies, do stars exist on thier own, with or without a posible solar sistem?
Is it posible to detect a "solo star" away from the influence of any galaxies?

I've modeled the evolution of globular clusters in speeded-up-time, with my computer. They do eject stars from time to time from "slingshot" events - which means that they interact so that the orbital energy of a star pair is partially stolen by a third star, which then begins moving with a speed higher than the escape speed from that part of the cluster. I never tried doing that with a whole galaxy because the number of stars is too big. But I guess the same thing happens. Yeah, there would be stars in intergalactic space.

Galaxies also have "halos" of globular clusters that give a kind of weak "elliptical galaxy" envelope even to spiral galaxies. Those clusters might be ejectees that didn't get quite enough energy to escape, so they keep going in-and-out of the galaxy on orbits of high eccentricity.

All stars that we know of formed within galaxies. Between galaxies there is probably not a large enough conglomeration of matter for a star to form. It is possible for a star to get thrown out of a galaxy, but they are few and far between.

confident, there are stars obtainable outdoors of galaxies. they start off in a galaxy yet get tossed out as a consequence of galactic collisions and so on. whilst the Milky way collides with Andromeda in 2.5 billion years or so, there's a small probability our equipment would be flung out. There are not too many such stars, nevertheless. A equipment flung out of its galaxy will proceed on only nice, yet like quite a few massive call it is going to ultimately die out--and massive call *formation* happens in galaxies.

Look on the web for photos of "colliding" galaxies (e.g. http://antwrp.gsfc.nasa.gov/apod/ap971022.html). There are long streamers from each galaxy, made of millions of stars pulled from their galactic orbits by gravity (actually, for more than 2 objects, "orbit" is a bit of a misnomer - the path may be chaotic).
Once the star (and any planets) are pulled loose, it is unlikely to be recaptured. How would the nighttime sky appear from a planet of a run-away star?

Stars do exist between galaxies, but they are fairly rare. It's also quite possible that they could have planets, but, due to the distances involved, we can't actually 'see' or 'measure' any planets around any of the known ones.

HTH ☺

It looks like the answer is yes to both your questions. According to the article, 10% of the mass of the Virgo cluster is made up of extragalactic stars, so they're not exactly rare!

I guess one could be ejected but the distances are so great that one star could never be seen to be any great distance from a galaxy

Yes. In the form of single stars and in clusters. They get ejected from their original positions by interactions with other high-gravity fields.

stars are confined withing galaxies, the space between our galaxy (milky way) and the andromeda galaxy, is just black space.
