Effects of orbital ellipticity on collisional disruptions of rubble-pile asteroids
Celestial mechanics Methods:numerical Minor planets,asteroids:general Planets and satellites:physical evolution
2015/12/25
The behavior of debris ejected from asteroids after collisional disruptions has significant implications for asteroid evolution. Analytical approximations of the elliptic restricted three-body system ...
Numerical predictions of surface effects during the 2029 close approach of Asteroid 99942 Apophis

2015/12/25
Asteroid (99942) Apophis’ close approach in 2029 will be one of the most significant small-body encounter events in the near future and offers a good opportunity for in situ exploration to determine t...
Collisional evolution and reddening of asteroid surfaces–I. The problem of conflicting time-scales and the role of size-dependent effects

2015/12/25
Space weathering is the generic term used for processes that modify the optical properties of surfaces of atmosphereless rocky bodies under exposure to the space environment. The general agreement abo...
Space plasma effects on Earth-spaceand satellite-to-satellite communications:Working Group 4 overview
Earth-spaceand satellite-to-satellite Space plasma
2015/9/14
This paper summarizes the the activities carried out by Working Group 4 of COST 271 Action. The structure of this Working Group included four Working packages that were dealing with different aspects ...
The Effects of Refractive Index Mismatch on Multiphoton Fluorescence Excitation Microscopy of Biological Tissue
scattering spherical aberration refractive index mismatch two-photon microscopy multiphoton fluorescence excitation microscopy
2015/5/21
Introduction: Multiphoton fluorescence excitation microscopy (MPM) is an invaluable tool for studying processes in tissue in live animals by enabling biologists to view tissues up to hundreds of micro...
Pressure support versus thermal broadening in the Lyman alpha forest - I. Effects of the equation of state on longitudinal structure
low-density intergalactic gas temperature
2014/12/22
In the low-density intergalactic medium that gives rise to the Lyman α (Lyα) forest, gas temperature and density are tightly correlated. The velocity scale of thermal broadening and the Hubble flow ac...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
The interstellar medium is not necessary fully ionized. When a shock propagates into the partially ionized medium, some neutral particles leak into the upstream region from the downstream region. In t...

2012/2/21
In this paper we study the chemical history of low-mass star-forming (SF) galaxies in the local Universe clusters Coma, A1367, A779, and A634. The aim of this work is to search for the imprint of the ...
On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites: atmospheres – radiative transfer
2011/9/29
Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clouds/hazes a...
