The nature of the X-ray point source in the bar of NGC 6822. [PDF]

open access: yesThe Astronomical Journal, 1997
We have analysed archival ROSAT PSPC and Einstein HRI data for the x-ray point source in the bar of NGC 6822. The source decreased in x-ray flux by at least half an order of magnitude in the 13 years between the HRI and PSPC observations. It has a PSPC flux of f_X = 8 x 10E-14 erg/cm^2/s, giving L_X = 2.4 x 10E36 erg/s for a distance of 500 kpc.

Fully open-flavor tetraquark states $$bc\bar{q}\bar{s}$$ bcq¯s¯ and $$sc\bar{q}\bar{b}$$ scq¯b¯ with $$J^{P}=0^{+},1^{+}$$ JP=0+,1+

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We have studied the masses for fully open-flavor tetraquark states $$bc\bar{q}\bar{s}$$ bcq¯s¯ and $$sc\bar{q}\bar{b}$$ scq¯b¯ ($$q=u, d$$ q=u,d ) with quantum numbers $$J^{P}=0^{+},1^{+}$$ JP=0+,1+ .

Arm morphology in off-centre barred galaxies

open access: yesAstronomy & Astrophysics
Context. Many barred galaxies, including the Large Magellanic Cloud (LMC), display strong lopsidedness and off-centre bars. The dynamical connection between bar–disc misalignments, internal-mass asymmetries, and arm morphology has not yet been fully ...

Periodic control of the bar with point mass

open access: yesMechanics / AGH University of Science and Technology, 2008
The following article discusses the usage of optimization theory with quasi periodic control to form a vibrating bar with point mass that is situated on the bar's axis. The maximum principle was changed and used to calculate a numerical sample.
