Nonextensive distributions of asteroid rotation periods and diameters
Context. We investigate the distribution of asteroid rotation periods from different regions of the solar system and diameter distributions of near-Earth asteroids (NEAs). Aims. We aim to verify if nonextensive statistics satisfactorily describes the data. Methods. Light curve data were taken from the Planetary Database System (PDS) with Rel ≥ 2. We also considered the taxonomic class and regio...
متن کاملThe shallow magnitude distribution of asteroid families
It is well known that asteroid families have steeper absolute magnitude (H) distributions for H 12–13 values than the background population. Beyond this threshold, the shapes of the absolute magnitude distributions in the family/background populations are difficult to determine, primarily because both populations are not yet observationally complete. Using a recently generated catalog containin...
متن کاملThe effect of the dust size distribution on asteroid polarization
We have developed a theoretical description of how of an asteroid’s polarizationphase curve will be affected by the removal of the dust from the surface due to a sizedependent phenomenon such as radiation pressure-driven escape of levitated particles. We test our calculations against new observations of four small (D ≈ 1 km) nearEarth asteroids [(85236), (142348), (162900) and 2006 SZ217] obtai...
متن کاملOn the statistical distribution of dust devil diameters
Dust devil diameters, like many features in nature, have skewed distributions. I summarize, and present in a unified manner, literature values of dust devil optical diameters from seven terrestrial surveys, three rover-based surveys on Mars and two orbital surveys on Mars. The problems of appropriately treating these data are analogous to those for impact craters, and similar display and binnin...
متن کاملParametric Probability Distribution Functions for Axon Diameters of Corpus Callosum
Axon diameter is an important neuroanatomical characteristic of the nervous system that alters in the course of neurological disorders such as multiple sclerosis. Axon diameters vary, even within a fiber bundle, and are not normally distributed. An accurate distribution function is therefore beneficial, either to describe axon diameters that are obtained from a direct measurement technique (e.g...
