Constraining values of bag constant for strange star candidates
We provide a strange star model under the framework of general relativity by using a
general linear equation of state (EOS). The solution set thus obtained is employed on …

On the lack of thermal emission from the quiescent black hole XTE J1118+ 480: evidence for the event horizon
JE McClintock, R Narayan… - The Astrophysical …, 2004 - iopscience.iop.org
A soft component of thermal emission is very commonly observed from the surfaces of
quiescent, accreting neutron stars. We searched with Chandra for such a surface component …

Compact strange stars with a medium dependence in gluons at finite temperature
Aims. The possible existence of strange stars in the universe will help in the understanding
of various properties of quantum chromodynamics, like asymptotic freedom and chiral …

A model finding a new Richardson potential with different scales for confinement and asymptotic freedom, by fitting the properties of Δ++ and Ω−
M Bagchi, M Dey, S Daw, J Dey - Nuclear Physics A, 2004 - Elsevier
Phenomenological Richardson potential has built in asymptotic freedom (AF in short) and
confinement, with only one parameter Λ in the potential. But it is known that the scales of AF …

Have we observed the skin vibration of realistic strange stars (ReSS)?
Skin vibration of ReSS and consequent resonance absorption can account for the
absorption lines in the spectrum of X-ray emission from many compact stellar objects and in …

Strange pulsar hypothesis
It appears that there is a genuine shortage of radio pulsars with surface magnetic fields
significantly smaller than∼ 108 G. We propose that the pulsars with very low magnetic fields …

Possible evidence of surface vibration of strange stars from stellar observations
S Ray, J Dey, M Dey, S Bhowmick - Monthly Notices of the Royal …, 2004 - academic.oup.com
Emission lines in the eV and keV range by certain stellar candidates from their recent
analysis invoke the question of their possible origin. The stars under consideration are 4U …
