Pulsar Near the Supernova Remnant RCW 103
Received ; accepted – 2 – ABSTRACT We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4−0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617−5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 ...
متن کاملthe impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
15 صفحه اولInfrared spectroscopy of young supernova remnants heavily interacting with the interstellar medium ⋆ I . Ionized species in RCW 103
ISO spectral observations of the supernova remnant RCW103 are presented. This object is the prototype of relatively young remnants ( 103 yr) with fast shocks (vs 1000 km/s) interacting with dense interstellar medium. The spectrum is dominated by prominent lines of [NeII], [SiII], [FeII] and other low excitation species which provide, for the first time, a simple and reliable estimate of the gas...
متن کاملKinematics of the Pencil Nebula ( RCW 37 ) and its association with the young Vela supernova remnant RX
The association between the Pencil nebula (RCW 37, NGC 2736), the Vela X-ray fragment D/D' and the recently discovered new X-ray supernova remnant (RX J0852.0-4622) in Vela is investigated. Recently published Chandra images of D/D' are compared with optical images of RCW 37 and confirm the close association of the two objects. New optical line profiles of RCW 37 from an extended slit position p...
متن کاملThe Rayleigh-Taylor instability and the origin of filamentary structures in the Vela supernova remnant
The nature of the Vela X-ray ”jet”, recently discovered by Markwardt & Ögelman (1995), is examined. It is suggested that the ”jet” arises along the interface of domelike deformations of the Rayleigh-Taylor unstable shell of the Vela supernova remnant; thereby the ”jet” is interpreted as a part of the general shell of the remnant. The origin of deformations as well as the general structure of th...
