High Resolution Spectroscopy of Balmer - Dominated Shocks in the RCW 86 , Kepler and SN 1006 Supernova Remnants ⋆
We report results from high resolution optical spectroscopy of three non-radiative galactic supernova remnants, RCW 86, Kepler’s supernova remnant and SN 1006. We have measured the narrow component Hα line widths in Balmer-dominated filaments in RCW 86 and SN 1006, as well as the narrow component width in a Balmer-dominated knot in Kepler’s SNR. The narrow component line widths measured in RCW ...
متن کاملPulsar 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 کاملBalmer-Dominated Spectra of Nonradiative Shocks in the Cygnus Loop, RCW 86 and Tycho Supernova Remnants
We present an observational and theoretical study of the optical emission from nonradiative shocks in three supernova remnants: the Cygnus Loop, RCW 86 and Tycho. The spectra of these shocks are dominated by collisionally excited hydrogen Balmer lines which have both a broad component caused by proton-neutral charge exchange and a narrow component caused by excitation of cold neutrals entering ...
متن کاملInfrared 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 کاملAn unresolved X - ray source inside the supernova remnant RCW 86
We report on the discovery of an unresolved X-ray source inside the supernova remnant G315.4-2.3 (RCW 86). The source is located 7 to the Southwest of the geometrical centre and may be close to the actual explosion centre of the supernova, which makes this a candidate for the stellar remnant associated with RCW 86. However, the presence of a possible optical counterpart with V ∼ 14 at 3 from th...
