Quaoar is a classical Trans-Neptunian Object (TNO) with an area equivalent diameter of 1,100 km and an orbital semi-major axis of 43.3 astronomical units. Based on stellar occultat…
Capture and migration of Jupiter and Saturn in mean motion resonance in a gaseous protoplanetary disc
Raul O. Chametla, Gennaro D'Angelo, Mauricio Reyes-Ruiz +1
We study the dynamical evolution of Jupiter and Saturn embedded in a gaseous, solar-nebula-type disc by means of hydrodynamics simulations with the FARGO2D1D code. We study the evo…
Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations
Marc W. Buie, Simon B. Porter, Peter Tamblyn +130
We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…
First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects
Samuel Navarro-Meza, Michael Mommert, David Trilling +6
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic t…
Multi-filter transit observations of HAT-P-3b and TrES-3b with multiple Northern Hemisphere telescopes
Davide Ricci, Pedro Valdés Sada, Samuel Navarro-Meza +17
We present a photometric follow-up of transiting exoplanets HAT-P-3b and TrES-3b, observed by using several optical and near-infrared filters, with four small-class telescopes (D =…
DDOTI: the deca-degree optical transient imager
Alan M. Watson, William H. Lee, Eleonora Troja +18
DDOTI will be a wide-field robotic imager consisting of six 28-cm telescopes with prime focus CCDs mounted on a common equatorial mount. Each telescope will have a field of view of…
First Results from the Rapid-Response Spectrophotometric Characterization of Near-Earth Objects using UKIRT
M. Mommert, D. E. Trilling, D. Borth +7
Using the Wide Field Camera for the United Kingdom Infrared Telescope, we measure the near-infrared colors of near-Earth objects (NEOs) in order to put constraints on their taxonom…
Dynamical Heating Induced by Dwarf Planets on Cold Kuiper Belt-like Debris Disks
Marco A. Muñoz-Gutiérrez, Barbara Pichardo, Mauricio Reyes-Ruiz +1
With the use of long-term numerical simulations, we study the evolution and orbital behavior of cometary nuclei in cold Kuiper belt-like debris disks under the gravitational influe…
Multi-filter transit observations of WASP-39b and WASP-43b with three San Pedro Mártir telescopes
D. Ricci, F. G. Ramón-Fox, C. Ayala-Loera +6
Three optical telescopes located at the San Pedro Mártir National Observatory were used for the first time to obtain multi-filter defocused photometry of the transiting extrasolar…
A dynamical stability study of Kepler Circumbinary Planetary systems with one planet
C. E. Chavez, N. Georgakarakos, S. Prodan +2
To date, 17 circumbinary planets have been discovered. In this paper, we focus our attention on the stability of the Kepler circumbinary planetary systems with only one planet, i.e…
Chaotic Dynamics of Comet 1P/Halley; Lyapunov Exponent and Survival Time Expectancy
M. A. Muñoz-Gutiérrez, M. Reyes-Ruiz, B. Pichardo
The orbital elements of comet Halley are known to a very high precision, suggesting that the calculation of its future dynamical evolution is straightforward. In this paper we seek…
Web-based tools for the analysis of TAOS data and much more

A preliminary data analysis of the stellar light curves obtained by the robotic telescopes of the TAOS project is presented. We selected a data run relative to one of the stellar f…
Stability of the Outer Planets in Multiresonant Configurations with a Self-gravitating Planetesimal Disk
Mauricio Reyes-Ruiz, Hector Aceves, Carlos E. Chavez
We study the effect of a massive planetesimal disk on the dynamical stability of the outer planets assuming, as has been suggested recently, that these were initially locked in a c…
