STARQUEEN in M16 Velocity?

STARNIGHTER · Post #1by **STARNIGHTER** » 06.02.2007, 14:23

Can anyone enlighten me as to whether or not the relative motion of the Starqueen nebula in M16 is known? I'm aware of high velocity motion within the nebula, as well as its distance and size, but I'm interested in knowing approximately how fast this nebula is moving (away from us, towards us, radial, etc.). I've contacted many observatories, as well as doing basic searches, but haven't found this issue addressed. Thanks!

I finally got the link you sent me (SYMASKI62) to open, and even after switching to English, I did not find any information as to the relative motion of M16 (with regards to the general nebula moving towards us or away, etc.). Forgive me if I just didn't see it amidst the generous information that is there on the link.

I have all the information I need regarding the M16, excluidng it's general motion relative to either the galaxy, or relative to our system. Just need to know which way it's heading, and how fast. Thanks for the help, and thanks in advance to anyone who can help with this information!

Starnighter,

It's probably reasonable to associate the aggregate radial and proper motions of all of the members of the cluster to the nebula.

SIMBAD claims

Code: Select all

Proper motion (mas/yr) [error ellipse]
   .62 -.32 
Radial velocity (v:Km/s) or Redshift (z)
   v +18.00 [ .58]

Thanks, Selden! That was the info I was looking for.

It's always a good idea to bookmark the professional data base Simbad if you are interested in state of the art astronomical results. Secondary info can only be worse ;-)

I just got done re-reading Simbad, and bookmarking it! You read my mind.

A great source of information!
