Investigating the low-flux states in six Intermediate Polars
Ava E. Covington, Aarran W. Shaw, Koji Mukai +30
We present optical photometry of six intermediate polars that exhibit transitions to a low-flux state. For four of these systems, DW Cnc, V515 And, V1223 Sgr and RX J2133.7+5107, w…
A Single-chord Stellar Occultation by the Extreme Trans-Neptunian Object (541132) Leleākūhonua
Marc W. Buie, Rodrigo Leiva, John M. Keller +32
A stellar occultation by the extreme large-perihelion trans-Neptunian object (541132) Leleākūhonua (also known by the provisional designation of 2015 TG387) was predicted by the Lu…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
Size and shape of Chariklo from multi-epoch stellar occultations
R Leiva, B Sicardy, J I B Camargo +28
We use data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity. We consider four possible models for Ch…
The structure of Chariklo's rings from stellar occultations
D. Bérard, B. Sicardy, J. I. B. Camargo +79
Two narrow and dense rings (called C1R and C2R) were discovered around the Centaur object (10199) Chariklo during a stellar occultation observed on 2013 June 3. Following this disc…
Study of the plutino object (208996) 2003 AZ84 from stellar occultations: size, shape and topographic features
A. Dias-Oliveira, B. Sicardy, J. L. Ortiz +60
We present results derived from four stellar occultations by the plutino object (208996) 2003~AZ, detected at January 8, 2011 (single-chord event), February 3, 2012 (multi-c…
