TL;DR: In this paper, the authors observed a stellar occultation by Titan from La Palma Observatory using ULTRACAM with three Sloan filters: u, g, and i (358, 487, and 758 nm, respectively).
Journal ArticleDOI
174P/Echeclus and its Blue Coma Observed Post-Outburst
TL;DR: In this article, the authors obtained consistent visual-near-infrared (VNIR) reflectance spectra of the sporadically active centaur 174P/Echeclus during a period of inactivity in 2014 and six weeks after its outburst in 2016 to see if activity had observable changed the surface properties of the nucleus.
Journal ArticleDOI
The scattered trans‐Neptunian object 1998 XY95
TL;DR: In this paper, a new trans-Neptunian object, 1998 XY95, was discovered as part of a deep search, and the current best-fitting orbit is unstable, but remains within a band of semi-major axis approximately 2-au wide.
