The first sentence says, "... when [two objects] merge in a binary system." Odd wording. Sounds a bit like they merge into a binary system. Is it intended to mean, "... when [two objects] in a binary system merge into each other"? Nurg ( talk) 00:19, 17 October 2017 (UTC)
I think that it would be useful to give a brief history (and etymology) of the word "kilonova" as this was unfamiliar to me before October 16, 2017. Is this a new word? Is a kilonova another word for a "short-duration GRB" (a term that has existed for decades) or is it slightly different? OtterAM ( talk) 11:41, 17 October 2017 (UTC)
Should the article put more emphasis on the history of observation of short-duration GRBs? For example, optical counterparts to this class of GRBs were studied as early as 2005, and it was pretty well accepted that their most likely explanation was a collision of two neutron stars. The September 2017 event confirmed this model, of course. OtterAM ( talk) 11:44, 17 October 2017 (UTC)
If a black hole's involved in the merge, the neutron star will likely be absorbed by the black hole. If two neutron stars merge, will they always produce a black hole? Or can they produce a "new" neutron star of their combined masses? Ximalas ( talk) 18:49, 25 October 2017 (UTC)

Nova says "peak absolute magnitude is bimodal, with a main peak at magnitude −8.8, and a lesser one at −7.5.", supernova has table suggesting peak absolute magnitudes between -14 and -22 (averages by subtype). What range and distribution of absolute magnitudes do kilonovae have, or do they not have a visual magnitude ? - Rod57 ( talk) 15:18, 30 October 2017 (UTC)
Searching for the absolute magnitude of such an event turns up very little. We don't have peak absolute magnitude numbers here or on GW170817. Would love to get this number. Zelmerszoetrop ( talk) 17:44, 12 April 2019 (UTC)
There is no mention of it beyond "r-process". While the link used explains a lot, there's stuff relevant to kilonovas specifically. Key in there would be what's left behind. Is there a remnant? Or just debris? Will ( Talk - contribs) 03:22, 20 November 2023 (UTC)
