Burst–Disk Interaction in 4U 1636–536 as Observed by NICER
نویسندگان
چکیده
We present the detection of 51 thermonuclear X-ray bursts observed from 4U 1636-536 by Neutron Star Interior Composition Explorer (NICER) over course a three year monitoring campaign. performed time resolved spectroscopy for 40 these and showed existence strong soft excess in all burst spectra. The emission can be characterized use scaling factor (f_a method) to persistent source, which is attributed increased mass accretion rate on neutron star due Poynting-Robertson drag. also model taking into account reflection off disk. spectral analysis 5 simultaneously NICER AstroSat, confirm main results with even greater precision. Finally, we evidence Compton cooling using 7 contemporaneously \nustar, means correlated decrease hard lightcurve as start.

Interaction of Hydrogen and Deuterium with Dislocations in Palladium as Observed by Small Angle Neutron Scattering
Small angle neutron scattering (SANS) measurements on Pd samples containing dislocations with a density of a few 10 cm 2 reveal an additional intensity for a scattering vector of 0.02 Å 1 to 0.2 Å 1 after loading with hydrogen (H) or deuterium (D). The corresponding net cross section is inversely proportional to the scattering vector as expected for line type scattering objects with a superimpo...

Long-Range Lipid-Water Interaction as Observed by ATR-FTIR Spectroscopy.
It is commonly assumed that the structure of water at a lipid-water interface is influenced mostly in the first hydration layer. However, recent results from different experimental methods show that perturbation extends through several hydration layers. Due to its low light penetration depth, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy is specifically suited t...
متن کاملInteraction of Mycoplasma hyopneumoniae with the porcine respiratory epithelium as observed by electron microscopy.
An in vivo-passaged strain of Mycoplasma hyopneumoniae attained viability titers of 10(6) to 10(8) color-changing units per mg of tissue in pig lungs and caused gross and histological pulmonic lesions. Mycoplasmas were readily located in the lumina of the respiratory tract by electron microscopy. In sections of tissue fixed in glutaraldehyde-osmium, the organisms were found to possess many radi...
متن کاملThe X-ray spectrum of the bursting atoll source 4U 1728-34 observed with INTEGRAL
We present for the first time a study of the 3–200 keV broad band spectra of the bursting atoll source 4U 1728-34 (GX 354-0) along its hardness intensity diagram. The analysis was done using the INTEGRAL public and Galactic Center deep exposure data ranging from February 2003 to October 2004. The spectra are well described by a thermal Comptonization model with an electron temperature from 35 k...
