On the DEWLine 2.0: Dwight Williams

Okay, where was I? 50 Leonis, Bowler 15 (yes, there's a star with that actual catalogue number!), 5 Puppis, Omicron Leonis, Ross 391...

A StarTrek StarCharts/StellarCartography question:

I suspect that HD 29172 used to be the preferred host star for Rotarran, thanks to the Hipparcos Mission data. Gaia Mission seems to have corrected the location of that star from 204 ly from Sol to 521 ly, though.

Granted that the shows as broadcast from 2017 are mostly sticking with the XY placements of known stars as published back in 2002. That's an editorial decision I mostly accept.

Here's some of the candidates I'm looking at, encircled for your review and discussion. Among them, HD 17224 is an A0V, and the thing that gives me pause about that star is that it's over 300 ly "below" Z=0.

I'm looking for opinions, rather than definitive answers here.

Chores.

That's my word for today.

Bedding-laundry, shopping, computer-mouse replacement, new colour-pencils for Mom, and if I can push myself the rest of the way, new storage bins to keep the basement reorg process going. Not sure that last item is going to be doable with today's local weather. Hot and humid.

Talked with the writer of San Francisco 2161 last night about proposed maps for his now-finished Trek-inspired fanfic project about the negotiations to co-found the Federation. What maps should there be attached, what forms they should take, that sort of thing.

I'm also toying with an idea for a prose fanfic project of my own centred on one of the participants in that story and a prequel, In the Raptor's Claws about the Coaltion-Romulan War that preceded the Federation. Specifically Nathan Samuels, whom Enterprise-watchers may remember as portrayed by Harry Groener. Not sure if this is going to go anywhere beyond maybe a couple of paragraphs before getting derailed by a job offer or loss of housing or whatever.

We'll see.

This system's about 34 light-years away.

This paper argues for five:

This one argues for six:

If I understand what I'm reading correctly.

For Trek purposes? Romulan territory until the supernova that burns Romulus and Remus is my guess.

For Marvel, DC, Honorverse, Babylon 5, Galaxy Quest, Alien, Traveller, or anything else? I dunno yet. (Well, maybe Solarian League for the Honorverse? Do I want to keep caring about that anymore?)

Entertaining accident: Decades ago, when Masao Okazaki was putting his Starfleet Museum site together, he assigned the name "Axolotl" to a planet orbiting Gliese 767A.

In 2019, the IAU and Mexico named the star HD 224693 "Axólotl" as part of that year's Name ExoWorlds event.

We have precedent in Star Trek for this sort of thing, thankfully, so I'm not worrying over it.

Having a little fun with the map projects before bed. Equuelus, Hercules, Sagitta, Corona Borealis, Aquila, that general neighbourhood. Places like Kitalpha, Ancha, Bunda, Libertas? Breen neighbourhoods!

I needed to correct for Puerto Rico.

I don't think that 42 Ursae Majoris is a good candidate for the Persephone system. It looks like a potential neighbour when you view the galaxy from above/below, sure...

I finally learned about data accuracy grading in SIMBAD a couple of nights ago. They have a five-level scale currently, going from A (best) to E (worst), and that letter is usually at the back end of the "Spectral type:" line item in any given star's profile data. For example, "F5V C". "F5 E" for another.

Of course, I'm making do with the data I have and the published and aired location data from the episodes and movies of the various branch series of Star Trek here...
