On the origins of part-time radio pulsars
Growing evidence suggests that some radio pulsars only act sporadically. These ‘part-time’ pulsars include long-term nulls, quasi-periodic radio flares in PSR B1931+24, as well as the so-called Rotating Radio Transients (RRATs). Based on the assumption that these objects are isolated neutron stars similar to conventional radio pulsars, we discuss two possible interpretations to the phenomenon. ...
متن کاملOn the Nature of Part Time Radio Pulsars
The recent discovery of rotating radio transients and the quasi-periodicity of pulsar activity in the radio pulsar PSR B1931+24 has challenged the conventional theory of radio pulsar emission. Here we suggest that these phenomena could be due to the interaction between the neutron star magnetosphere and the surrounding debris disk. The pattern of pulsar emission depends on whether the disk can ...

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
On the absence of mildly recycled radio pulsars amongst the population of ordinary single radio pulsars
Current scenarios for the evolution of binaries predict that only 1%or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths B > 1012 G the period vs. magnetic field diagram shows no evidence for injection of pulsars at P ∼ 0.5 s. For magnetic...
متن کاملKinematics of Radio Pulsars
A very good fraction of stars in the sky are believed to be in binary (or multiple) systems. Therefore, we expect a good fraction of pulsars to have originated in binary systems. However, observations of pulsars have shown that most of the pulsars are not in binary system now. This would imply that these pulsars must have become solitary after the disruption of their progenitor binary system du...
