Gǃkúnǁʼhòmdímà[edit]

Hi. You wrote, "added calculated diameter of 229762 G!kun?'homdima from Ortiz et. al. 2018 refit of the occultation with the eighth chord included (678 x 678 x 611.4 km)."

Could you provide a link to the ref? — kwami (talk) 02:41, 8 January 2020 (UTC)[reply]

Here - https://arxiv.org/ftp/arxiv/papers/1905/1905.04335.pdf Ortiz et. al. 2019 - 16th page, the occultation results have been refitted with the new chord from Sierra RO added.

"Diameter cannot be calculated from two axes" -- indeed. But that's precisely what our source did. If the source made such a basic error, why do we trust their figures at all? (Though I think they might mention it's just the size of the occultation shadow.) Also, we don't know that we saw Gǃkúnǁʼhòmdímà along its equatorial plane, which means its polar diameter may well be less that what we list. Do we have any way of knowing its effective diam actually is 655km? — kwami (talk) 20:01, 8 January 2020 (UTC)[reply]

Correct - I know this. The original fit presented results with a Maclaurin fit with the observed ellipse having an equatorial diameter of 676 km, and a equivalent diameter of 638 km (therefore making the minor axis 600 km - ((638 x 2) - 676 = 600), with an effective diameter (assuming a Maclaurin spheroid shape) 650.7 km. The new Sierra RO chord seems to make the fit larger - dimensions of 678 x 611.4 km, with an equivalent diameter of 644.7 km ((611.4 + 678)/2 = 644.7), and an effective diameter (assuming a Maclaurin spheroid shape) 655.8 km. It is true that the true oblateness cannot be well established, but among the three occultation papers so far the observed apparent oblatenesses are consistently low (0.118/0.106, Bendetti-Rossi, et. al. 2017, 0.0982, Ortiz, et. al. 2019, 0.0743, Schindler, et. al. 2016) suggesting that the true oblateness is not much higher than 0.12 - making G!kun?'homdima a Maclaurin spheroid - and therefore making the effective diameter 655.8 km. I know that this is most likely not the actual diameter for G!kun?'homdima but it is at least better than averaging only two axes. I'm trying to follow the precedent set in 174567 Varda's article - the mean diameter was updated from 756.5 km to 767.7 km - the result of switching to a three axis calculation instead of a two-axis calculation - this was reflected on the "List of possible dwarf planets" article. We need to be consistent - if Varda's diameter is calculated with a three-axis solution (767.7 km), the G!kun?'homdima's diameter should also be calculated this way (655.8 km). Hope this explains my thinking a bit better. Ardenau4 (talk) 02:11, 9 January 2020 (UTC)[reply]

New 'AD' paper[edit]

Hi Ardenau4,

I saw that on the talk for the list of largest stars, you mentioned a certain AD paper. Could you please share this paper with me? Also, could you please share your personal list so I may add it to the temporary 'new' list of largest stars?

Thanks!

Grammar[edit]

I have encountered a lot of articles where you have added text including the words "based off of" (eg [1], [2], [3]). Would you please use the grammatically-correct "based on" in future. Sankura (talk) 08:25, 1 August 2020 (UTC)[reply]

Oof thanks for catching that! Yeah I'll make sure to note that lmao.

SPI[edit]

An editor has opened an investigation into sockpuppetry by you. Sockpuppetry is the use of more than one Wikipedia account in a manner that contravenes community policy. The investigation is being held at Wikipedia:Sockpuppet investigations/SevenSpheresCelestia, where the editor who opened the investigation has presented their evidence. Please make sure you make yourself familiar with the guide to responding to investigations, and then feel free to offer your own evidence or to submit comments that you wish to be considered by the Wikipedia administrator who decides the result of the investigation. If you have been using multiple accounts (in a manner contrary to Wikipedia policy), please go to the investigation page and verify that now. Leniency is usually shown to those who promise not to do so again, or who did so unwittingly, but the abuse of multiple accounts is taken very seriously by the Wikipedia community.
