Adaptive learning for financial markets mixing model-based and model-free RL for volatility targeting
Eric Benhamou, David Saltiel, Serge Tabachnik +2
Model-Free Reinforcement Learning has achieved meaningful results in stable environments but, to this day, it remains problematic in regime changing environments like financial mar…
Dynamical Habitability of Known Extrasolar Planetary Systems
Kristen Menou, Serge Tabachnik
Habitability is usually defined as the requirement for a terrestrial planet's atmosphere to sustain liquid water. This definition can be complemented by the dynamical requirement t…
Asteroids Observed by The Sloan Digital Sky Survey
Z. Ivezic, M. Juric, R. H. Lupton +2
We announce the first public release of the SDSS Moving Object Catalog, with SDSS observations for 58,117 asteroids. The catalog lists astrometric and photometric data for moving o…
Color Confirmation of Asteroid Families
Z. Ivezic, R. H. Lupton, M. Juric +6
We discuss optical colors of 10,592 asteroids with known orbits selected from a sample of 58,000 moving objects observed by the Sloan Digital Sky Survey (SDSS). This is more than t…
Structure of Possible Long-lived Asteroid Belts
N. W. Evans, S. A. Tabachnik
High resolution simulations are used to map out the detailed structure of two long-lived stable belts of asteroid orbits in the inner Solar system. The Vulcanoid belt extends from…
Maximum likelihood method for estimating the mass and period distributions of extra-solar planets
Serge Tabachnik, Scott Tremaine
We investigate the distribution of mass M and orbital period P of extra-solar planets, taking account of selection effects due to the limited velocity precision and duration of exi…
Apsidal Alignment in Upsilon Andromedae
E. I. Chiang, S. Tabachnik, S. Tremaine
One of the parameters fitted by Doppler radial velocity measurements of extrasolar planetary systems is omega, the argument of pericenter of a given planet's orbit referenced to th…
Solar System Objects Observed in the SDSS Commissioning Data
Z. Ivezic, S. Tabachnik, R. Rafikov +4
We discuss measurements of the properties of about 10,000 asteroids detected in 500 deg2 of sky in the Sloan Digital Sky Survey (SDSS) commissioning data. The moving objects are de…
Asteroids in the Inner Solar System II - Observable Properties
N. W. Evans, S. A. Tabachnik
This paper presents synthetic observations of long-lived, coorbiting asteroids of Mercury, Venus, the Earth and Mars. Our sample is constructed by taking the limiting semimajor axe…
Asteroids in the Inner Solar System I - Existence
S. A. Tabachnik, N. W. Evans
Ensembles of in-plane and inclined orbits in the vicinity of the Lagrange points of the terrestrial planets are integrated for up to 100 million years. The integrations incorporate…
Possible Long-Lived Asteroid Belts in the Inner Solar System
Wyn Evans, Serge Tabachnik
The recent years have witnessed a carnival of discoveries in the Outer Solar System. Here we provide evidence from numerical simulations of orbital stability to suggest the possibl…
Cartography for Martian Trojans
Serge Tabachnik, N. Wyn Evans
The last few months have seen the discovery of a second Martian Trojan (1998 VF31), as well as two further possible candidates (1998 QH56 and 1998 SD4). Together with the previousl…
