Basic Astronomy Questions [CLEAN STAMP]

Subject: Basic Astronomy Questions [CLEAN STAMP]

Hi all,

I have been looking through the star maps and lists on the
"GZG Encyclopedia Galactica" web site, (Excellent site!)
and I'm a little confused about how to read the star list.
Can anyone answer a couple of basic astronomy questions?

The star called "Gl 732" is listed as having (being in?)
the spectrum called "sdG0" -- this must be an abbreviation
for something, but for the life of me I can't figure out what.

The star called "CD-38 10983" is listed with the spectrum "G3/5".
Is this a binary star, one of which is G3 and the other is G5?

The star called "LTT 6453" is listed with the spectrum "k-m".
Does this mean it's somewhere between K and M (orange-red)?

The star called "SM 34" is listed with the spectrum "K9 V J".
What does the "J" mean?

The star called "SM 11" is listed with the spectrum "K7 Ve".
What does "Ve" mean (as opposed to plain old "V")?

Thanks in advance for any help!
