Chandra and XMM-Newton X-ray Study on the Core-collapse Supernova Remnant N63A in an H II Region

Hanxiao Chen, Yang Chen, Lei Sun +1

N63A is one of the brightest supernova remnants (SNRs) in the Large Magellanic Cloud and provides an excellent laboratory for studying SNR evolution in an H II region. We present a…

A pulsar escaping an ancient open cluster via tidal stripping

Lei Zhang, Xiaoting Fu, Di Li +21

Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…

A Complete X-ray View of Supernova Remnant W28 with Einstein Probe: Spatial Distribution of Parameters and Origin of the Thermal-Composite Morphology

Yi-Heng Chi, Ping Zhou, Yang Chen +6

It has been an unsolved question what leads a supernova remnant (SNR) to a thermal composite rather than a typical shell-like morphology, and what causes recombining plasma inside…

Evolution of X-ray Gas in SN 1987A from 2007 to 2021: Ring Fading and Ejecta Brightening Unveiled through Differential Emission Measure Analysis

Lei Sun, Salvatore Orlando, Emanuele Greco +4

As the nearest supernova (SN) observed since Kepler's SN of 1604, SN 1987A provides an unprecedented opportunity to study in detail the early evolution of supernova remnants (SNRs)…

Unusual X-ray Oxygen Line Ratios of SN 1987A Arising From the Absorption of Galactic Hot Interstellar Medium

Lei Sun, Salvatore Orlando, Emanuele Greco +5

Recent high-resolution X-ray spectroscopic studies have revealed unusual oxygen line ratios, such as the high O VII forbidden-to-resonance ratio, in several supernova remnants. Whi…

Optical observations of the Galactic SNR HB9 and H II region G159.2+3.3

Jiang-Tao Li, Li-Yuan Lu, Huiyang Mao +4

Context. We present multi-wavelength observations of the Galactic SNR HB9 and the H II region G159.2+3.3 apparently projected nearby, in order to study their properties and potenti…
