Next: The Stopping Radius in Up: ``Ecology'' of Magnetic Rotators Previous: The Environment of the . Now we consider qualitatively the effect of the electromagnetic field of a magnetic rotator on the accreting plasma. ... What is important is that both relativistic particles and magnetic dipole radiation will transfer their momentum and hence exert pressure on the accreting plasma. ... 2) The pressure of the accreting plasma is high enough to permit the plasma to enter the light cylinder . ...

The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

The Southern African Large Telescope (SALT) was a relatively cheap (~$20M) 10m class telescope, for which the construction phase was completed, relatively quickly, by late 2005. ... These cover a range of topics, and some will focus on studies using the unique or rarer instrument capabilities for large telescopes. Finally, I look to the future of SALT and the prospects of new instruments and capabilities and I will also discuss some of other new SAAO facilities and future plans. ...
... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

... Калибровка снимка - это удаление из него паразитной информации, которая включает в себя: темновой шум, горячие пиксели, шум считывания (ток смещения), а также тени от пыли на матрице и оптике. Для калибровки снимка нужно подготовить снимки с паразитной, т.е. нежелательной информацией. В первую очередь нам нужно получить мастер-кадр шума считывания (ток смещения), на западе снимок шума считывания называют Bias или Offset . ... Уровень темнового шума сильно зависит от температуры матрицы. ...
... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...

Given a subset A of the primes and a positive integer N, we define the relative density delta (N,A) of the set of elements of A less than N as the quotient between the number of elements af A up to N and the number of primes up to N. Ben Green proved that if N is large enough and if the relative density delta (N,A) is large ...
... Stars . ... Cepheid variable stars have been known since the 18th century. ... Regularly brightening to a peak over days, weeks or months before fading these variable stars were remarkable curiosities to astronomers in past centuries.€а The term Cepheid is taken from the star Delta Cephei in the constellation of Cepheus, which was identified as variable€а in 1784 by the teenaged prodigy John Goodricke (1764-96). ...
