Asteroid sizes determined with stellar occultations
Context Asteroid sizes, even for large objects are surprisingly poorly determined. As the MP3C database (https://mp3c.oca.eu/) shows, many objects in the range of a few tens of km to 100 km have diameter determinations ...Anna Marciniak +3 more

Prospects of stellar occultations with robotic telescopes
Stellar occultations are influential for determining shapes, sizes, and rotation states, as well as characterizing the binary population, ring systems,and debris. Additionally, occultations are a source of high-precision astrometry.I will present a new project to implement a network of telescopes dedicated to observing stellar occultations by Solar ...Rodrigo Leiva +6 more

Stellar occultation lightcurve modeling for elliptical occulting bodies
2001We present a new method of calculating model lightcurves for stellar occultations by the Jovian planets. We model the occulting planet as a three-dimensional body of non-zero ellipticity, and define two ellipses of intersection with the body which dictate the appearance of the lightcurve.

Studying Asteroids Via Stellar Occultations
There are over two million minor planets in the Solar System, which include the populations of asteroids, Kuiper Belt and trans-Neptunian objects, centaurs, and trojans, among others. These bodies frequently pass in front of stars, casting shadows across the surface of the Earth in events known as stellar occultations.openaire +1 more source
Prediction of stellar occultations by satellite of asteroids
2004Our group is working on the orbit determination of asteroid satellites on the last four years gathering data recorded with several AO systems. Based upon our observations, we focused specifically on models for (22) Kalliope, (121) Hermione, (45) Eugenia and (90) Antiope systems characterizing accurately their dynamical and physical properties (Marchis ...
