... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ... Right: the image of the comet 29P/Schwassmann-Wachmann 1 obtained at the 6-m telescope. ...

Cas is a main sequence B-type star, and together with other such stars showing hydrogen emission it forms the class of "Be stars", where the "e" stands for emission. ... Struve further speculated that those stars would be surrounded by a disk, basically thrown off the stellar surface by the rapid rotation. ...

... Abrikosov strings arise in some superconductors when the level of the external magnetic field exceeds a certain critical value. Then the superconductivity starts to break down by forming normal conductivity zones inside the superconductor, looking like strings stretched along the direction of the field. ... Moreover, a reduction of Seiberg--Witten equations to such complex Abrikosov strings can be defined, leading to systems of vortex equations on their normal bundles. ...

... SHTOL ' Special Astrophysical Observatory of the Russian AS, Nizhnij Arkhyz 357147, Russia The investigation of such a phenomenon as the magnetic field variability at long times (years - decennials) is very interesting. If the explanation of the magnetic field variability with rotation period by the oblique rotator model is evident, then the reason of the long-period variability is not clear yet, despite the existence of some assumptions on its nature. ...

... The output file (in either format) directs the plotting package (gaia or ds9) to draw a circle of a certain radius at a certain sky position. The radius can be made an arbitrary function of column values in the input source table. The task first calculates the value of the column expression in parameter radiusexpression . ... If this is `raw' (the default), the task does no further processing: the result of evaluating radiusexpression is used directly as the radius of the circle to be plotted. ...
