چکیده

We investigate the magnitude and characteristics of the photocentre offset phenomenon of small solar system bodies, and compare different scenarios for correcting for it. We discuss the corresponding implications and limitations to the inverse problem of model construction based on astrometry with instruments such as GAIA.

Photocentre displacement of minor planets: analysis of Hipparcos astrometry

We present a study of the phase effect (or photocentre offset) on the astrometry of minor planets. Analysis of the high precision Hipparcos observations of the largest asteroids shows the validity of the model. Minor planets Ceres, Pallas, Vesta and Iris show a brightness distribution close to the lunar scattering properties, while Juno and Hebe are found to be more uniformly bright objects. Fo...

Prospects of Dynamical Determination of General Relativity Parameter β and Solar Quadrupole Moment J2⊙ with Asteroid Radar Astronomy

We evaluated the prospects of quantifying the parameterized post-Newtonian parameter β and solar quadrupole moment J2 with observations of near-Earth asteroids with large orbital precession rates (9 to 27 arcsec century). We considered existing optical and radar astrometry, as well as radar astrometry that can realistically be obtained with the Arecibo planetary radar in the next five years. O...

Asteroid 1566 Icarus’sSize, Shape, Orbit, and Yarkovsky Drift from Radar Observations

Near-Earth asteroid (NEA) 1566 Icarus ( = a 1.08 au, e=0.83, =  i 22 .8) made a close approach to Earth in 2015 June at 22 lunar distances (LD). Its detection during the 1968 approach (16 LD) was the first in the history of asteroid radar astronomy. A subsequent approach in 1996 (40 LD) did not yield radar images. We describe analyses of our 2015 radar observations of Icarus obtained at the ...

Updated analysis of the dynamical relation between asteroid 2003 EH 1 and comets C / 1490 Y 1 and C / 1385 U 1

The asteroid 2003 EH1, proposed as the parent body of the Quadrantid meteor shower, is thought to be the remnant of a past cometary object, tentatively identified with the historical comets C/1490 Y1 and C/1385 U1. In the present work we use recovery astrometry to extend the observed arc of 2003 EH1 from 10 months to about 5 years, enough to exclude the proposed direct relationship of the aster...

Astrometric effects of solar-like magnetic activity in late-type stars and their relevance for the detection of extrasolar planets

Using a simple model based on the characteristics of sunspots and faculae in solar active regions, the effects of surface brightness inhomogeneities on the position of the photocentre of the disk of a solar-like, magnetically active star, are studied. A general law is introduced, giving the maximum amplitude of the photocentre excursion produced by a distribution of active regions with a given ...
