An unusual glitch signature in the pulsar PSR B1822-09
Two glitches have been detected in the pulsar PSR B1822-09. The first glitch occurred around MJD 49615 and was characterized by a fractional increase in rotational frequency of 2×10−10. The second glitch occurred 325 days after the first one and caused a fractional change in frequency of 5×10−9. Of interest was the post-glitch behaviour. The rotational frequency immediately after the second gli...
متن کاملA Frequency Glitch in an Accreting Pulsar
Frequency glitches have been observed so far only in radio pulsars and anomalous X-ray pulsars. Here we present evidence of a glitch in a neutron star accreting from a Be companion. The transient KS 1947+300 reappeared in 2000 October as a moderately strong X-ray source that exhibited 18.7 s pulsations, leading to an identification with the BATSE source GRO J1948+32, last detected in 1994. We h...
متن کاملA Massive White Dwarf Companion to the Eccentric Binary Pulsar System PSR B2303+46
Pulsars in close, eccentric binary systems are usually assumed to have another neutron star as a companion. These double neutron star binaries have proven to be the best laboratories for experimental General Relativity and are the most secure candidates for gravitational wave interferometers. We present deep B, V , and R images of the field containing the eccentric binary pulsar system PSR B230...
متن کاملGlitch: A Live Programming Model
Input changes are often handled by reactive and incremental constructs that are tedious to use or inexpressive, while changes to program code are typically not handled at all during execution, complicating support for “live programming.” We propose that change in code and input should be managed automatically, similar to how garbage collection eliminates memory management as an explicit program...
متن کاملOn the Glitch Phenomenon
The Principle of the Glitch states that for any device which makes a discrete decision based upon a continuous range of possible inputs, there are inputs for which it will take arbitrarily long to reach a decision. The appropriate mathematical setting for studying this principle is described. This involves defining the concept of continuity for mappings on sets of functions. It can then be show...
