Unsure if anyone is still following this, but here's today addition to the list of clues:

 21 *|* 7 = 11
 17924 *|* 10751 = 851
 1089 *|* 121 = 2069
 10 *|* 23 = 6
 1 *|* 0 = 2
 999 *|* 909 = 1359
 14 *|* 14 = 14
 2 *|* 1 = 0
 1 *|* 1 = 1
 a *|* b = b *|* a
 a *|* a = a
 3 *|* 0 = 6
 13 *|* 8 = 18

A large number with a small number please? Let's say 17924 *|* 5.

[araver]

A large number with a small number please? Let's say 17924 *|* 5.

Certainly:

 21 *|* 7 = 11
 17924 *|* 10751 = 851
 1089 *|* 121 = 2069
 10 *|* 23 = 6
 1 *|* 0 = 2
 999 *|* 909 = 1359
 14 *|* 14 = 14
 2 *|* 1 = 0
 1 *|* 1 = 1
 a *|* b = b *|* a
 a *|* a = a
 3 *|* 0 = 6
 13 *|* 8 = 18
 17924 *|* 5 = 9329

[:-)]

Is a *|* 0 = 2*a?

[araver]

Is a *|* 0 = 2*a?

Not really, although in some cases it does. I'll add an example where it doesn't to the list.

 21 *|* 7 = 11
 17924 *|* 10751 = 851
 1089 *|* 121 = 2069
 10 *|* 23 = 6
 1 *|* 0 = 2
 999 *|* 909 = 1359
 14 *|* 14 = 14
 2 *|* 1 = 0
 1 *|* 1 = 1
 a *|* b = b *|* a
 a *|* a = a
 3 *|* 0 = 6
 13 *|* 8 = 18
 17924 *|* 5 = 9329
 16 *|* 0 = 23

Spoiler for your eyes only...

I'm intrigued...

1234 *|* 49
19 *|* 1

How long would it take you to calculate the above two operations individually? And do you use any type of calculator? Paper? Or is it all in your head?

Spoiler for Since you want it in a spoiler

1234 *|* 49=1780
19 *|* 1=10

And to answer your question: Well it takes a while cause it's not something you're accustomed to do. As I said it is alien. Aliens would probably take much less time.
I like to do it on paper just to be sure of the results, not to post a false answer. But I like to check it with a computer too (again, same reason).
I think it can be done in the head, at least for a small number of digits. For a large number even addition is hard, right?

I've been looking at this for a while. I'm still not seeing the overarching pattern, but is the following true?

Spoiler for maybe...

If a *|* b = c, then a *|* c = b and b *|* c = a.

Also, what are:

1 *|* 9
2 *|* 9

[k-man]

Spoiler for question for araver

Are these numbers in base 10?

I don't suppose that the aliens were using our representation of the digits even if they used a decimal system. So, is it fair to assume that all the numbers in the examples are decimal representation of the numbers?

Spoiler for For your first question:

Basically yes!

The rest:

1 *|* 9 = 20
2 *|* 9 = 19

Spoiler for answer

Indeed, they might not and the OP doesn't specify it, so it is a justified question.
I would advise you to treat the numbers in the examples as their normal decimal representation. Suppose the explorers figured out the numbering system first and you're looking at the translation to our familiar decimal representation.
