... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

Meteor Streams: the Relation to Hazardous Celestial Bodies . ... Analytically tractable, the evolution of meteor particles' elliptic orbits in a gravitational field of the Sun is considered in view of light pressure, the Poynting Robertson effect, and the corpuscular analogue of Poynting Robertson effect. ... In the context of the perturbed two-body problem, the criterion for the probable meteor particles parent bodies are identified. ...

... In this poster we propose a hypothesis that within fixed assumptions about internal physics (opacity, thermodynamics, nuclear reactions) a strict relation between the surface helium abundance and the entropy of the adiabatic part of the convective zone exists for all solar models. This hypothesis is verified with models under simplified physics (Christensen­Dalsgaard 1988) and with six evolutionary models computed by Christensen­Dalsgaard (1992). ... 1990, Christensen­Dalsgaard 1991). ...

Mira's comet-like tail . Ultraviolet images from NASA's Galaxy Evolution Explorer show a speeding star that is leaving an enormous trail of "seeds" for new solar systems. The star, named Mira after the Latin word for "wonderful," is shedding material that will be recycled into new stars, planets and possibly even life as it hurls through our galaxy. The Galaxy Evolution Explorer discovered the strange tail during part of its routine survey of the entire sky at ultraviolet wavelengths. ...
