Talk:Jupiter-mass binary object

Recent research suggests that these objects don't exist. Hobbema (talk) 09:36, 11 August 2025 (UTC)

added, but because the Nature article is paywalled it's just one sentence for now. Artem.G (talk) 13:59, 11 August 2025 (UTC)

The original paper

• Portegies Zwart, S., Hochart, E. Why wide Jupiter-mass binary objects cannot form. Nat Astron 9, 957–959 (2025). https://doi.org/10.1038/s41550-025-02609-4

However this paper claims that previous models explaining the formation are incorrect, rather than providing evidence against the observations. Johnjbarton (talk) 14:00, 11 August 2025 (UTC)

There was substantial contestation of the observational results ever since.

It should be highlighted that the original paper on JuMBOs discovery was not accepted for publication yet as all the news cite arxiv article, that is not confirmed as published. Astrotycho (talk) 01:04, 10 February 2026 (UTC)

The unpublished source

• Pearson, Samuel G.; McCaughrean, Mark J. (2 Oct 2023). "Jupiter Mass Binary Objects in the Trapezium Cluster". arXiv:2310.01231 [astro-ph.EP].

should not be summarized and not be cited in support of any claims.
