A Compact Central Object in the Supernova Remnant Kes 79

چکیده

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 properties are similar to the central source in Cas A even though the Kes 79 remnant is considerably older.

Discovery of a 105 Ms X-ray Pulsar in Kesteven 79: on the Nature of Compact Central Objects in Supernova Remnants

We report the discovery of 105-ms X-ray pulsations from the compact central object (CCO) in the supernova remnant Kes 79 using data acquired with the Newton X-Ray Multi-Mirror Mission. Two observations of the pulsar taken 6 days apart yield an upper limit on its spin-down rate of Ṗ < 7 × 10 s s and no evidence for binary orbital motion. The implied energy loss rate is Ė < 2 × 10 ergs s, surface...

We report the discovery of pulsed X-ray emission from the compact source 1E 1841−045, using data obtained with the Advanced Satellite for Cosmology and Astrophysics. The X-ray source is located in the center of the small-diameter supernova remnant (SNR) Kes73 and is very likely to be the compact stellar-remnant of the supernova which formed Kes73. The X-rays are pulsed with a period of ≃ 11.8 s...

Chandra View of Kes 79: a Nearly Isothermal Snr with Rich Spatial Structure

A 30 ks Chandra ACIS-I observation of Kes 79 reveals rich spatial structures, including many filaments, three partial shells, a loop and a “protrusion”. Most of them have corresponding radio features. Regardless of the different results from two non-equilibrium ionization (NEI) codes, temperatures of different parts of the remnant are all around 0.7 keV, which is surprisingly constant for a rem...

Revealing 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...

Probing the Proper Motion of the Central Compact Object in Puppis - A with the Chandra High Resolution Camera

By making use of the sub-arcsecond angular resolution of the High Resolution Camera (HRC-I) aboard the Chandra X-ray satellite we have examined the central compact object RX J0822−4300 in the supernova remnant Puppis-A for a possible proper motion. Using data which span an epoch of 1952 days we found the position of RX J0822−4300 different by 0.553 ± 0.212 arcsec, implying a proper motion of µ ...
