Does Celestia have other ponies "studying" other topics for her?

I think she has had students in the past but that Twilight is her only one at the moment.

This sort of links to the topic but I also wanted to post this somewhere because it makes me feel sad:

Wow Gingerpotato, I found myself nearly tearing up at that. It just makes you realize how sad Celestia is on the inside. When you've lived as long as she has with only your sister for constant company, you've had to see many people you care for leave this world while you lived on. I think that is part of why Celestia is such a kind ruler and tries to get to know her subjects as much as possible.

The curse of immortality, that is. Yes, a curse it is.

 

I think its likely that Celestia has just one lead apprentice at a time.

Thank you Gingerpotato. *sniff* That was beautiful~!

[Twi Rubix 726]

Most likely. It could be for all sorts of topics, or even some actual work like missions and such.

 

Come to think of it, does Celestia do anything but raise the sun and greet people at Galas? I imagine she does, but I never saw her do a whole lot.

I think Twilight is the only one. She's particularly gifted at magic and has known the Princess since a young age, add to that she and her friends wield the elements of harmony and you can see why Celestia would take an interest. Its some pretty exceptional circumstances.
