A novel approach to asteroid impact monitoring and hazard assessment

Javier Roa, Davide Farnocchia, Steven R. Chesley

Orbit-determination programs find the orbit solution that best fits a set of observations by minimizing the RMS of the residuals of the fit. For near-Earth asteroids, the uncertain…

A Recipe for Geophysical Exploration of Enceladus

Anton I. Ermakov, Ryan S. Park, Javier Roa +13

Orbital geophysical investigations of Enceladus are critical to understanding its energy balance. We identified key science questions for the geophysical exploration of Enceladus,…

Uniform formulation for orbit computation: the intermediate elements

Giulio Baù, Javier Roa

We present a new method for computing orbits in the perturbed two-body problem: the position and velocity vectors of the propagated object in Cartesian coordinates are replaced by…

Yarkovsky effect detection and updated impact hazard assessment for Near-Earth Asteroid (410777) 2009 FD

Alessio Del Vigna, Javier Roa, Davide Farnocchia +5

Near-Earth asteroid (410777) 2009 FD is a potentially hazardous asteroid with potential impacts on Earth at the end of the 22nd century. The astrometry collected during the 2019 ap…

Stability of exomoons around the Kepler transiting circumbinary planets

Adrian S. Hamers, Maxwell X. Cai, Javier Roa +1

The Kepler mission has detected a number of transiting circumbinary planets (CBPs). Although currently not detected, exomoons could be orbiting some of these CBPs, and they might b…

Nonconservative extension of Keplerian integrals and a new class of integrable system

Javier Roa

The invariance of the Lagrangian under time translations and rotations in Kepler's problem yields the conservation laws related to the energy and angular momentum. Noether's theore…
