Where is the co-author of a post saved? and how to retrieve with a query?

I need to do a one-time export, but I'm not able to find in the db where the are saved the info about co-author

Co-author data is saved as Taxonomy Terms

Could you tell me the term taxonomy label?

Probably I found !! But I really help your help

I can search into wp_term_taxonomy.taxonomy the author.

But the problem is I got a string like

"Mario Rossi Mario Rossi mario-rossi 344232"
or other times
"Luca D'Amato Luca D'Amato ldmatato 37 [email protected]"

Could you please tell me how to invoke some WP function and or something from your plugin to extract the label ?

because online I can see "Mario Rossi", or "Luca D'Amato" , but I cannot parse a string with a unknown format to extract first and last name of my author, having 'n' spaces, where 'n' is not a constant
