The space between the planets is far from empty. It contains: electromagnetic radiation (photons); hot plasma (electrons, protons and other ions) a.k.a. the solar wind ; cosmic rays; microscopic dust particles; and magnetic fields (primarily the Sun's). While the Sun 's radiation is obvious, the other components of the interplanetary medium were not discovered until very recently. ... Except near some of the planets, interplanetary space is filled with the Sun's magnetic field. ... Sun .. ...

... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

The Yarkovsky Effect in the Motion of NEAs . ... In this paper we evaluate the Yarkovsky effect on the motion of NEAs under the assumption that this acceleration depends on heliocentric distance as 1/r 2 and is characterized by the transverse component 2 in the orbital coordinate system. ... In some instances the Yarkovsky effect can be estimated by using only optical observations. Accounting for the Yarkovsky effect permits to include more optical observations in the orbit fitting process. ...

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...

If the rate of accretion from one star to another is sufficiently high (e.g., the mass transfer occurs on a timescale a few times shorter than the thermal Kelvin-Helmholz time for the normal companion) or the compact object is engulfed by a giant companion, the common envelope (CE) stage of the binary evolution can set in (see Paczynski 1976; van den Heuvel 1983). ...
