Early Stellar Flybys are Unlikely: Improved Constraints from Sednoids and Large- TNOs
Qingru Hu, Yukun Huang, Brett Gladman +1
Sedna-like objects (a.k.a. sednoids) are transneptunian objects (TNOs) characterized by large semimajor axes and exceptionally high perihelia. Their high- orbits are detached fr…
