... Direct observation of the vortex structure in high- T c superconductors in tilted magnetic fields. Abstract: . A high-resolution Bitter technique has been used to observe an effect of tilting the external magnetic field on the flux line lattice (FLL) in Tl 2 Ba 2 CaCu 2 O 8+x single crystals. ... The reason is believed to be that the formation of the equilibrium vortex state (vortex chains) was prevented by strong pinning, revealed for our crystals by the M(t) curves. ...

... We present the results of an ongoing survey of cool, late­type supergiants -- the descendants of massive O and B­type stars -- that has systematically detected magnetic fields in these stars using spectropolarimetric observations obtained with the ESPaDOnS at the Canada­France­Hawaii Telescope. Our observations reveal detectable, often complex Stokes V Zeeman signatures in the Least­Squares Deconvolution mean line profiles in a significant fraction of the observed sample of 30 stars. ...

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. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
