We present an update on the results of our monitoring observations of the X-ray remnant of supernova (SN) 1987A with Chandra. As of 2002 December, we have performed a total of seven observations of SN 1987A, which allows us to monitor the details of the earliest stage of the supernova remnant evolution in X-rays. The high angular resolution images from the latest data reveal developments of new X-ray-bright spots in the northwestern and the southwestern portions of the remnant, as well as…

Based on observations with the Chandra X-ray Observatory, we present the latest spectral evolution of the X-ray remnant of SN 1987A (SNR 1987A). We present a high-resolution spectroscopic analysis
Chandra Observes the End of an Era in SN 1987A
Updated imaging and photometric results from Chandra observations of SN 1987A, covering the last 16 years, are presented. We find that the 0.5–2 keV light curve has remained constant at ~8 × 10−12
SNR 1987A: OPENING THE FUTURE BY REACHING THE PAST
We report an upturn in the soft X-ray light curve of SNR 1987A in late 2003 (∼6200 days after the explosion), as observed with the Chandra X-Ray Observatory . Since early 2004, the rapid increase of
HIGH-RESOLUTION X-RAY IMAGING OF SUPERNOVA REMNANT 1987A
We report observations of the remnant of supernova 1987A with the High Resolution Camera (HRC) on board the Chandra X-ray Observatory. A direct image from the HRC resolves the annular structure of

Abstract The development of the radio remnant of SN 1987A has been followed using the Australia Telescope Compact Array since its first detection in 1990 August. The remnant has been observed at four
The Presupernova H II Region around SN 1987A
The slow expansion of the bright ring around SN 1987A and the large size estimated for the radio source at an age of ~1500 days suggest a low mass-loss rate, , from the blue supergiant progenitor
X-Ray and Ultraviolet Line Emission from SNR 1987A
The soft X-ray emission seen from SN 1987A and the apparent deceleration of the radio source expansion suggest that the supernova blast wave has encountered a moderately dense H II region interior to
