Ozone Depletion from Nearby Supernovae
Neil Gehrels, Claude M. Laird, Charles H. Jackman +3
Estimates made in the 1970's indicated that a supernova occurring within tens of parsecs of Earth could have significant effects on the ozone layer. Since that time, improved tools…
Evolution of Iron K Line Emission in the Black Hole Candidate GX 339-4
Y. X. Feng, S. N. Zhang, X. Sun +3
GX 339-4 was regularly monitored with RXTE during a period (in 1999) when its X-ray flux decreased significantly (from 4.2 erg cm to 7.6$\times 10^{-…
Three-Layered Atmospheric Structure in Accretion Disks Around Stellar-Mass Black Holes
S. N. Zhang, Wei Cui, Wan Chen +5
Modeling of the x-ray spectra of the Galactic superluminal jet sources GRS 1915+105 and GRO J1655-40 reveal a three-layered atmospheric structure in the inner region of their accre…
Evidence for Doppler-Shifted Iron Emission Lines in Black Hole Candidate 4U 1630-47
Wei Cui, Wan Chen, S. N. Zhang
We report the first detection of a pair of correlated emission lines in the X-ray spectrum of black hole candidate 4U 1630-47 during its 1996 outburst, based on RXTE observations o…
Strong Aperiodic X-ray Variability and Quasi-Periodic Oscillation in X-ray Nova XTE J1550-564
Wei Cui, S. N. Zhang, Wan Chen +1
We report the discovery of strong aperiodic X-ray variability and quasi-periodic oscillation (QPO) in the X-ray light curves of a new X-ray Nova, XTE J1550-564, and the evolution o…
The Progenitor of the New COMPTEL/ROSAT Supernova Remnant in Vela
Wan Chen, Neil Gehrels
We show that (1) the newly discovered supernova remnant (SNR), GRO J0852--4642/RX J0852.0--4622, was created by a core-collapse supernova of a massive star, and (2) the same supern…
