... The well-known spherical aberration in the OTA primary mirror causes most of the light for stellar targets to fall in a large halo (Figs. 2 and 3). The PSF core has nearly the correct diameter, but contains only about 15%of the light. ... The variations with field position are a large effect for WFPC images (Fig. ... This ``breathing'' of the OTA has a noticeable effect on the PSF wings for WFPC data; the wings expand and contract on a timescale comparable to the orbit period. ...

... OF MIR ORBITAL COMPLEX HARDWARE . ... Insufficient funds were compensated for by RSC Energia through of Contract activities. More than 60% of the entire scope of research both under the Russian, and International programs were performed on the MIR Station from 1995 through 2000. Within the final period (1997 - 2000) after the MIR final configuration as a research laboratory was completed, 138 space experiments were implemented under the science and application research program. ...

... Normalised spectra of all central stars of planetary nebulae observed in the 075.D-0289 campaign ordered by increasing effective temperature from top to the bottom. ... The presence of a magnetic field in the central star may be the reason for this lack of symmetry, but observational works published in the literature have so far reported contradictory results. ...

Magnetic stars, 2004, 212-215 Averaged stellar effective magnetic fields. ... The catalog is based on 12076 measurements of the stellar effective (or mean longitudinal) magnetic field strengths Be , which were compiled from the available literature. ... The first measurements of magnetic fields in stars were made more than 50 years ago (Babcock & Burd 1952). Since that time, both the number of magnetic field measurements and the number of investigated stars have grown enormously. ...

Next: Rapidly Rotating Stars Up: Discussion Previous: Relations . ... They attributed this to a mechanism which regulated stellar angular momentum through the accretion disk. ... While some of this may be due to sampling effects, the data seem to indicate that after a star loses its disk, either it continues its slow rotation for a period of time and then a rapid increase in rotation rate commences or spin up does not necessarily follow the loss of the disk. ...
