22. Magnetic field influence on martesite phase transition in Ni2+УMn1-УGa
Cherechukin A.A., Koledov V.V., Shavrov V.G., Tulaikova A.A., Vasil'ev A.N. Magnetic and structural phase transitions in Ni2+УMn1-УGa (0<У<1) alloys are investigated experimentally. The martensite domains formation under the action of external magnetic field on the surface of polycrystalline Ni2,19Mn0,81Ga specimen was investigated by optical method. ... It is found that the martensite phase formation temperature is enhanced by the order of 0,3 K in magnetic field of 1 kOe. ...

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...

. I will briefly summarise the methods to estimate the magnetic field strengths of different types of neutron stars and the caveats associated with them. In this context I will present some recent results we have obtained in finding the limits to the field strengths of accreting millisecond X-ray pulsars from the interaction between the accretion disk and neutron star magnetosphere.

32. Rivi: Magnetic Stars
... Be Stars . ... Magnetic Stars . ... Magnetic fields in stars are common. ... The earliest star known to have a magnetic field is the O-star 1 Ori C, one of trapezium stars in the central cluster of the Orion nebula of spectral type O6. ... The non-existence of more rapidly rotating magnetic stars was thought to be an immediate consequence of the magnetic field: The field would help the star to get rid of angular momentum by forcing the wind into co-rotation, and so to brake down the star. ...

35. Methodology of Time Delay Change Determination for Uneven Data Sets
... It was found in this way that the radio variations (5 MHz) followed the optical ones, but that the time delay was a linear function of time with the mean value being about 2370 days and with the rate of increase days/year. ... We take days/year as the test value. ... To show that the method has real abilities to determinate a value of of the time delay rate of increase in the light curves we again use Monte-Carlo simulation as it is explained in (1) and (2), but the actual value is 110 days/year. ...

37. Attitude variation
... A complication to transforming from CHIPCOORD to sky coordinates is that the spacecraft attitude is never completely fixed, thus the exact transform varies with time. ... Each chip image is subjected to multiple transforms, one per attitude bin; the output image consists of a weighted sum of these transformed images, the weights being proportional to the duration of each attitude bin (but see also section 3.2 below). ... It may for example be unwise to make OOTE sky maps this way. ...
