Cosmic rotation

Cosmic rotation, which appeared to be in geocentric mode, has been observed in radio astronomy (Birch, 1982) and excited the comment that ... [Pg.234]

Exceptionally violent phenomena can nevertheless disturb this fine order. Some of them bring tremendous speeds into play, in both translational and rotational motions. Solar and stellar flares come to mind, along with exploding stars and spinning pulsars (neutron stars). If part of this well-ordered energy is conferred upon an atomic nucleus, it then becomes a cosmic ray. It is thus excluded from the community, whose gentle brethren are no longer able to retain it. [Pg.31]

We give an estimation of the carbon fraction locked in these molecules. We discuss the rotation rates and electric dipole emission of hydrogenated icosahedral fullerenes in various phases of the interstellar medium. These molecules could be the carriers of the anomalous microwave emission detected by Watson et al. (Astrophys. J. 624 L89,2005) in the Perseus molecular complex and Cassasus et al. (2006) in the dark cloud LDN 1622. Hydrogenated forms of fullerenes may account for the dust-correlated microwave emission detected in our Galaxy by Cosmic Microwave Background experiments. [Pg.1]

Hydrogenated fullerenes and buckyonions may produce rotationally based electric dipole microwave radiation under the conditions of the diffuse interstellar medium. These molecules are potential carriers for the anomalous Galactic micro-wave emission recently detected by several cosmic microwave experiments. Their precise contribution to this emission should be fully investigated. [Pg.23]

Bob pushes the thoughts out of his mind and enjoys the grass. For centuries, scientists hypothesized that the Sun and planets were born from a rotating disk of cosmic gas and dust. The flat disk constrained the nascent planets to have orbits lying roughly in the same plane. This nebular theory was proposed as far back as 1755 by the philosopher Immanuel Kant. [Pg.92]

This cosmic spectroscopy method has been extended to study variation of other fundamental parameters. The ratio of the hydrogen atom hyperfme transition frequency to a molecular (CO, CN, CS, HCO+, HCN etc.) rotational frequency is proportional to y = a2gp where gp is the proton magnetic -factor [21]. A new preliminary result here is Ay/y = (—2.4 1.8) X 10-6 about 4 billion light years from us (the average z=0.47). Altogether, we now have 3 independent samples of data two optical samples (see [2,3]) and one radio sample. All 3 samples hint that Aa is negative. [Pg.566]

Herbig-Haro objects are often found to be associated with molecular outflows observed in rotational lines of cosmically abundant molecules (e.g. CO, NH3) that come from regions enveloping the jet. The outflow velocity is generally much lower. The origin of these molecular outflows is not clear either they result from winds from the accretion disk or from the interaction between the jet and its surroundings. [Pg.59]

The rotational energy of a young pulsar with period P that remains after the supernova explosion is estimated to be 2 x 105O(10 ms// )2 erg and may provide an additional energy reservoir for the acceleration of cosmic rays. [Pg.133]

Studies carried out during recent years have demonstrated the connection of life cycles of individual organisms and their communities and the universal cycling processes. The latter arises from the geophysical and cosmic events such as rotation of the Earth about its axis and about the Sun, the natural evolution of solar matter, the... [Pg.2]

P13.30 The question of whether to use CN or CH within the interstellar cloud of constellation Ophiuchus for the determination of the temperature of the cosmic background radiation depends upon which one has a rotational spectrum that best spans blackbody radiation of 2.726 K. Given flo(CH) = 14.90 cm-1, the rotational constant that is needed for the comparative analysis may be calculated from the 226.9 GHz spectral line of the Orion Nebula. Assuming that the line is for the l2Cl4N isotopic species and J + 1 <— 7=1, which gives a reasonable estimate of the CN bond length (117.4 pm), the CN rotational constant is calculated as follows. [Pg.264]

It is an intriguing fact that nucleons in nuclei, electrons in atoms, as well as large cosmic objects such as solar systems and ev galaxies, are more dominated by rotational than by linear motion, although in our daily life the latter seems to be a more common phenomenon. In rotation there is a balance between two forces the centrifugal force of inertia, which tries to move a body away from a center point, and an attractive force (gravitational, electrostatic, etc.), which opposes the separation. [Pg.303]
