The OP asked "[ELW orbiting a Class L star?] Is that an oddity? A tidally locked ELW at that. I've never run across one...just curious. "
The answer to that question is relative to "oddity", but by the standards of other ELWs, it isn't really an "oddity". If you want to go and define "oddity" different, knock yourself out, but for people who actually follow the rarities of the stellar bodies. and spend exhaustive time cataloguing them - like I have - then it isn't. You may as well say "you found any ELW at all, what an oddity!" and you'd still be "technically correct".
I'd like to be able to tell you the rarity of ELWs with primary class L-stars, because that is far lower, but the query is taking excessively long to complete.
Exactly the same problem applies to your attempt to use the entire galaxy in when comparing L type stars with ELWs.
See above. It is still quite rare!
Another edit: I think I've visited around 400,000 star systems. So I should have seen 28 of those particular ELWs. Maybe accurate?
