Detection of Coma Activity of the ACO/Quasi-Hilda Object, 212P/2000YN30

TL;DR

This paper investigates the cometary activity of 212P/2000YN30, a quasi-Hilda object, revealing its past activity and current dust tail structure through orbital analysis and observations.

Contribution

It presents the first evidence of cometary activity in 212P/2000YN30 and analyzes its orbital history indicating a past active comet phase.

Findings

Detected dust tail structure between January and March 2009

Orbital calculations suggest past cometary activity

Object was likely active before current quasi-stable orbit

Abstract

The quasi-Hilda object, 212P/2000YN30 with a cometary-like orbit, was found to display a dust tail structure between January and March, 2009. From orbital calculations, it is shown that this object could have been an active comet in its past history before being transported to the current orbital configuration in quasi-stable 3:2 resonance with Jupiter.
