The highest efficiency of converting rest mass into energy by accreting matter into a Kerr black hole is approximately 31% (Thorne 1974). We propose a new process in which periods of accretion from a thin disk, and the associated spin-up of...

Very recently the Chandra first light observation discovered a point-like source in the Cassiopeia A supernova remnant. This detection was subsequently confirmed by the analyses of the archival data from both ROSAT and Einstein observations...
A Model for the Quiescent Phase of the Recurrent Nova U Scorpii [0.03%]
UC sco的名字为UScorpii,简称U_Sco。淬灭期指的是复发新星经历大爆发之后的宁静期。题目可以翻译为“大爆发型复发新星USco的淬灭期模型”。此题目的翻译建议为:“复发新星UC Sco的静默期模型”

A theoretical light curve is constructed for the quiescent phase of the recurrent nova U Scorpii in order to resolve the existing distance discrepancy between the outbursts (d approximately 6 kpc) and the quiescences (d approximately 14 kpc...
Evolutionary Timescale of the Pulsating White Dwarf G117-B15A: The Most Stable Optical Clock Known [0.03%]

We observe G117-B15A, the most precise optical clock known, to measure the rate of change of the main pulsation period of this blue-edge DAV white dwarf. Even though the obtained value is only within 1 sigma, P&d2;=&parl0;2.3+/-1.4&parr0;x1...
Discovery of a New Pulsating X-Ray Source with a 1549.1 Second Period, AX J183220-0840 [0.03%]

A new pulsating X-ray source, AX J183220-0840, with a 1549.1 s period was discovered at R.A.=18h32m20s and decl.=-8&j0;40'30" (J2000, with an uncertainty of 0&farcm;6) during an ASCA observation on the Galactic plane. The source was observe...
First Mass-resolved Measurement of High-Energy Cosmic-Ray Antiprotons [0.03%]

D Bergström et al.
We report new results for the cosmic-ray antiproton-to-proton ratio from 3 to 50 GeV at the top of the atmosphere. These results represent the first measurements, on an event-by-event basis, of mass-resolved antiprotons above 18 GeV. The re...
Detection of Polarized Millimeter and Submillimeter Emission from Sagittarius A* [0.03%]

DK Aitken et al.
We report the detection of linear polarization from Sgr A* at 750, 850, 1350, and 2000 µm which confirms the contribution of synchrotron radiation. From the lack of polarization at longer wavelengths, it appears to arise in the millimeter/...

Planetary nebulae (PNe) in the Large Magellanic Cloud (LMC) offer the unique opportunity to study both the population and evolution of low- and intermediate-mass stars, by means of the morphological type of the nebula. Using observations fr...

We discuss the spectrum arising from synchrotron emission by fast cooling (FC) electrons, when fresh electrons are continually accelerated by a strong blast wave, into a power-law distribution of energies. The FC spectrum has so far been de...
Multiple Sub-Jet Model of Gamma-Ray Bursts and Possible Origin of X-Ray Precursors and Postcursors [0.03%]

We assume that internal shocks of gamma-ray bursts (GRBs) consist of multiple sub-jets with a collimation half-angle of about several times gamma-1i, where gammai is the Lorentz factor of each sub-jet. If by chance a sub-jet is first emitte...
