... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

The CCD acts as a storage medium, and with frame times of the order seconds, there is no obvious method of employing prompt co-incidence rejection of charged particle events. ... In conventional CCDs, a m track length results in an equivalent energy deposition of 5 - 6 keV, and significant confusion with X-ray events arises. ...

The aromatic features in M101 were studied spectroscopically and photometrically using observations from all three instruments on the Spitzer Space Telescope. The global SED of M101 shows strong aromatic feature (commonly called PAH feature) emission. ... This implies that the weakening of the aromatic emission in massive star-forming regions is due primarily to processing of the dust grains in these environments, not to differences in how they form. ...

... The photon temperature now is T p = 2.728 K and the neutrino temperature now is 1.947 K. If neutrinos are massless then we can compute their equivalent mass density using rho = [Q/a 3 ]/c 2 = N n (2\sigma/c)(7/8)g f T n 4 where N n is the number of neutrino species: N n = 6 for 3 types of neutrinos and 3 types of anti-neutrinos. ... Because this behavior is caused by the thermal velocity of the neutrinos, this form of dark matter is called Hot Dark Matter . ...

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 .. ...

We have obtained simultaneous high resolution H alpha and Na I D spectra of five dwarf M stars that span a wide range in chromospheric activity level. ... However, the H alpha line systematically indicates a value for the mass loading at the onset of the Transition Region and the location of T_min that is 0.4 dex lower in column mass density than that indicated by NaI D. Therefore, the profile of both lines cannot be simultaneously well fit for all but one of our stars. ...
