In this White Paper we present the potential of the enhanced x-ray Timing and Polarimetry(exTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass x-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. exTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the exTP mission is expected to be launched in the mid 2020s.

This is a general review Oil the observations and physics of black hole x-ray binaries and microquasars, with the emphasize on recent developments in the high energy regime. The focus is put on understanding the accretion flows and measuring the parameters of black holes in them. It includes mainly two parts： i） Brief review of several recent review article on this subject; ii） Further development on several topics, including black hole spin measurements, hot accretion flows, corona formation, state transitions and thermal stability of standard think disk. This is thus not a regular bottom-up approach, which I feel not necessary at this stage. Major effort is made in making and incorporating from many sources useful plots and illustrations, in order to make this article more comprehensible to non-expert readers. In the end I attempt to make a unification scheme on the accretion-outflow （wind/jet） connections of all types of aecreting BHs of all accretion rates and all BH mass scales, and finally provide a brief outlook.

We test different x-ray spectrum models to find the one that best represents the observed Rossi x-ray Timing Explore/Proportional Counter Array (RxTE /PCA) spectra of Her x-1 during Main High state (MH). We then apply this model to MH observations taken over the lifetime of RxTE. From the results, we obtain patterns in the spectral parameters vs. 35-day phase during MH. The precessing-disc occultation model explains the 35-day cycle by changes in observer view of the emission regions by the accretion disc 35-day precession. Qualitatively, we find that this model can describe the main spectral changes. However, several spectral parameters show detailed changes that the models have not addressed yet. These changes will likely require modifications to the basic precessing-disc model for the 35-day cycle.

The archival Rossi x-ray Timing Explorer (RxTE) Proportional Counter Array (PCA) observations of HZ Her/Her x-1 are analyzed here. The time periods for Anomalous Low States are refined. The 35-day x-ray lightcurve of Her x-1 is produced using 35-day phases determined with RxTE All-Sky Monitor (ASM) and Swift Burst Alert Telescope (BAT) data, with adjustments based on the RxTE/PCA data. As a result, we constructed the best-phased 35-day lightcurve of Her x-1 with the highest sensitivity. The RxTE/PCA data are separated into 8 different substates of the 35-day cycle: Main High (MH) turn-on, MH, MH decline, Low State (LS) 1, Short High (SH) turn-on, SH, SH decline, and LS2. Orbital lightcurves are created for each substate, and they are compared. Eclipse data are extracted for each substate to determine the changes in eclipse shape with 35-day phase. A scattering corona model is fit to the eclipses for the different 35-day substates: this shows that the corona is present with similar intensity at all 35-day phases. We search for previously reported dips without absorption but find none.

The Effects of A Varying Accretion Rate and Spiral Density W...

学位级别：硕士

Most accretion disc models consider the accretion rate to be steady and nonvarying or run disk simulations with one accretion rate at a time to determine how the different rates affect disk dynamics. However, in the case of a black hole accreting from its companion star, the accretion rate should progressively vary since the star may still be evolving and because of additional mass that is loss via the stellar winds. In order to investigate how a varying accretion rate in the context of spiral density waves effect the dynamics of the disc:I use the recently made public code, Fargo3d, to simulate the effects of a varying accretion rate and compare them with a simulation of a consistent accretion rate. Three different accretion rates, one of which was constant, were supplied to magnetized thin disks with an aspect ratio of0.1. The results indicate that there is indeed a difference between a constant accretion rate and a varying one as both of the disks with the varying accretion rates produced more turbulence over time, i.e. a high value of alpha(the turbulent velocity over the sound speed), than the constant accretion rate. It is also worth noting that the accretion rate with the least total mass of the three had a greater value than the constant accretion rate. This may have great implications in the way we view disk models as the assumption of a constant accretion rate may not be as inconsequential as proposed.
