THE SINGLE-DEGENERATE BINARY ORIGIN OF TYCHO'S SUPERNOVA AS TRACED BY THE STRIPPED ENVELOPE OF THE COMPANION
X-ray arc Tycho's supernova
2014/12/20
We propose that a nonthermal X-ray arc inside the remnant of Tycho's supernova (SN) represents the interaction between the SN ejecta and the companion star's envelope lost in the impact of the explosi...
Supersoft X-ray Phase of Single Degenerate Type Ia Supernova Progenitors in Early Type Galaxies
Supersoft X-ray Phase Single Degenerate Type
2011/1/13
In the single degenerate (SD) scenario for Type Ia supernova (SN Ia) progenitors, an accreting white dwarf (WD) is expected to undergo a supersoft X-ray source (SSS) phase. Recently, Gilfanov & Bogdan...
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Around several single DAZ and DBZ white dwarfs metal-rich disks have been observed, which are mostly believed to originate from disruption of smaller rocky planetesimals. In some cases the material do...
The HST/ACS Coma Cluster Survey III. Structural Parameters of Galaxies using single-Sérsic Fits
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the HST/ACS Coma Treasury Survey. Parameters from S\'ersic fits to the two-dimensional surface brightness distribu...
Stellar models of massive single stars are still plagued by major uncertainties. Testing and calibrating against observations is essential for their reliability.
Consistency relation for the Lorentz invariant single-field inflation
shape bispectrum Lorentz invariant single-field inflation
2010/3/19
In this paper we compute the sizes of equilateral and orthogonal shape bispectrum for the general Lorentz invariant single-field inflation. The stability of field theory implies a non-negative square ...

A GLOBULAR-CLUSTER MODEL WITH VARIABLE MEAN MASS OF A SINGLE STAR
GLOBULAR-CLUSTER MODEL SINGLE STAR VARIABLE MEAN MASS
2009/4/8
The application of the basic hydrodynamical equations to globular
clusters is reconsidered. As usually, these stellar systems are assumed to be
spherically symmetric and in a steady state with an is...
THE DISK EMISSION IN SINGLE PEAKED LINES FOR 12 AGNs
Galaxies active-Line formation-Plasmas
2009/1/15
The disk emission in the single peaked Broad Emission Lines (BELs)
of Active Galactic Nuclei (AGNs) is di±cult to detect. In order to ¯nd the disk
traces in BELs the line pro¯les were simu...
