The planetary and lunar ephemerides called DE440 and DE441 have been generated by
fitting numerically integrated orbits to ground-based and space-based observations …

Access to microarcsecond astrometry is now routine in the radio, infrared (IR), and optical
domains. In particular, the publication of the second data release (Gaia DR2) from the Gaia …

The stellar occultation technique provides competitive accuracy in determining the sizes,
shapes, astrometry, etc., of the occulting body, comparable to in-situ observations by …

Context. The Centaur (10199) Chariklo has the first ring system discovered around a small
object. It was first observed using stellar occultation in 2013. Stellar occultations allow sizes …

PRAIA–Package for the Reduction of Astronomical Images Automatically–is a suite of
astrometric and photometric tasks designed to cope with huge amounts of heterogeneous …

Context. The tenuous nitrogen (N 2) atmosphere on Pluto undergoes strong seasonal effects
due to high obliquity and orbital eccentricity, and has recently (July 2015) been observed by …

A stellar occultation by Pluto on 5 September 2019 yielded positive detections at two
separate stations. Using an approach consistent with comparable studies, we derived a …

Context. Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary
system formation, and their physical properties have invaluable information for evolutionary …

A stellar occultation by Pluto was observed on 2020 June 6 with the 1.3 m and 3.6 m
telescopes located at Devasthal, Nainital, India, using imaging systems in the I and H bands …

We report observations of a stellar occultation by Pluto on 2019 July 17. A single-chord high-
speed (time resolution= 2 s) photometry dataset was obtained with a CMOS camera …
