A Compact Central Object in the Supernova Remnant Kes 79
A Chandra X-ray observation has detected an unresolved source at the center of the supernova remnant Kes 79. The best single-model fit to the source spectrum is a blackbody with an X-ray luminosity L X (0.3-8.0 keV)=7×10 33 ergs s −1. There is no evidence for a surrounding pulsar wind nebula. There are no cataloged counterparts at other wavelengths, but the absorption is high. The source proper...
متن کاملRevealing the Obscured Supernova Remnant Kes 32 with Chandra
I report here on the analysis and interpretation of a Chandra observation of the supernova remnant Kes 32. Kes 32 is rather weak in X-rays due to a large interstellar absorption, which is found to be ∼ 4 × 10 cm, larger than previously reported. Spectral analysis indicates that the ionization age of this object is very young, with net ∼ 4×10 9 cms, and a temperature of kTe ∼ 1 keV. The X-ray em...
متن کاملBeppoSAX observations of the young pulsar in the Kes 75 Supernova Remnant
We present the results of BeppoSAX observations of the young X–ray pulsar PSR J1846–0258, recently discovered at the center of the composite supernova remnant Kes 75. The pulsar (plus nebula) spectrum can be fitted by an absorbed power law with photon index αph = 2.16 ± 0.15, NH = (4.7 ± 0.8)× 10 cm−2, and unabsorbed flux ∼ 3.9 × 10−11 erg cm−2 s−1 (2–10 keV). By joining two observations taken ...
متن کاملASCA Observations of the Supernova Remnant VRO 42 . 05 . 01
We present the results of our ASCA SIS and GIS observations of the supernova remnant VRO42.05.01. Our spectral fits indicate that the SNR is isothermal (∼ 8.3 × 10 6 K), consistent with our ROSAT analysis results. The absorbing column density (∼ 2.9 × 10 21 cm −2) obtained from these spectral fits is much smaller than expected for the nominal distance of 5 kpc, indicating that the line of sight...
متن کاملA 700 Year - Old Pulsar in the Supernova Remnant Kes 75
Since their discovery 30 years ago, pulsars have been understood to be neutron stars (NSs) born rotating rapidly (∼ 10 − 100 ms). These neutron stars are thought to be created in supernova explosions involving massive stars, which give rise to expanding supernova remnants (SNRs). With over 220 Galactic SNRs known (Green 1998) and over 1200 radio pulsars detected (Camilo et al. 2000), it is quit...
