Suzaku Observation of 30 Dor C: A Supernova Remnant with the Largest Non-Thermal Shell
This paper reports on the Suzaku results of thermal and non-thermal features of 30 Dor C, a supernova remnant (SNR) in a superbubble of the Large Magellanic Cloud (LMC). The west rim exhibits a nonthermal X-ray spectrum with no thermal component. A single power-law model is rejected but a powerlaw model with spectral cutoff is accepted. The cutoff frequency of (3− 7)× 10 Hz is the highest among...
متن کاملThe Optical Spectrum of the Sn 1006 Supernova Remnant Revisited
We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the NW rim of SN 1006. We detect the broad and narrow components of Hα, Hβ and Hγ and report the first detection of the He I λ 6678 emission line in this supernova remnant. We may have detected, at the 1.5σ level, faint He II λ4686 emission. We measure a full width half maximum of 2290± 80 km s in the broad c...
متن کاملThe X-ray Spectrum of Supernova Remnant 1987A
We discuss the X-ray emission observed from Supernova Remnant 1987A with the Chandra X-ray Observatory. We analyze a high resolution spectrum obtained in 1999 October with the high energy transmission grating (HETG). From this spectrum we measure the strengths and an average profile of the observed X-ray lines. We also analyze a high signal-to-noise ratio CCD spectrum obtained in 2000 December....

The Remnant of Supernova 1987A
Although it has faded by a factor of ∼107, SN 1987A is still bright enough to be observed in almost every band of the electromagnetic spectrum. Today, the bolometric luminosity of the debris is dominated by a far-infrared (∼200 μm) continuum from ∼0.5 M of dust grains in the interior debris. The dust is heated by UV, optical, and near-infrared (NIR) emission resulting from radioactive energy de...
