Sentences with phrase «region of the accretion»

«The gravitational energy is released gradually, so the glowing region of the accretion disk is fairly extended,» Reynolds says.

To get a better handle on how much energy those photoionized atoms consume, researchers at Osaka University in Japan attempted to recreate conditions in the region of an accretion disk that would be nearest a black hole.

«The gravitational energy is released gradually, so theglowing region of the accretion disk is fairly extended,» saysReynolds.

This new finding indicates that the jet indeed carries away part of the angular momentum (rotational momentum) from the material in the innermost region of the accretion disk (space hamburger), which is rotating around the central protostar.

Not exact matches

The study found cooler sea temperatures, greater precipitation and stronger upwelling — all indicators of La Niña - like conditions at the study site in Panama — during a period when coral reef accretion stopped in this region around 4,100 years ago.

The sun formed at the hot and dense centre of this disc, while the planets grew by accretion in the cooler outer regions.

Meanwhile, a correlation between the rate at which stars form in the central regions of galaxies and the amount of gas that falls into supermassive black holes (mass accretion rate) was known to exist, leading some scientists to suggest that the activity involved in star formation fuels the growth of black holes.

We interpret this periodicity as a property of the accretion disc, most likely a long - term precession, where the disc edge structure and X-ray irradiation is responsible for the hard X-ray dips and modulation, although we discuss other possible explanations, including Lense - Thirring precession in the inner disc region and spectral state variations.

With this, two new phenomena have been discovered: the fast flares in the early light curve seen from days 9 - 15 (which have no proposed explanation) and the optical dips seen out of eclipse from days 41 - 61 (likely caused by raised rims of the accretion disk occulting the bright inner regions of the disk as seen over specific orbital phases).

NuSTAR's observations revealed that the black hole's gravity pulled the coronal X-ray light onto the inner regions of Mrk 335's accretion disk.
