I review the method of Doppler tomography which is widely used to understand the complex emission line profile variations displayed by accreting binary stars. Doppler tomography uses the information encoded in line profiles as a function of orbital phase to calculate the strength of emission as a function of velocity, using a process closely related to medical X-ray tomographic imaging. I review applications which have revealed spiral structures in accretion discs, the accretion flows within… 

Three dimensional Doppler tomography

Doppler tomography is a method to compute the emissivity distribution within the co-rotating frames of binary stars from observations of their emission line profiles at multiple orbital phases. A key

Using Optical Spectroscopy to Map the Geometry and Structure of the Irradiated Accretion Discs in Low-mass X-ray Binaries: The Pilot-Study of MAXI J0637−430

The recurring transient outbursts in low-mass X-ray binaries (LMXBs) provide us with strong test-beds for constraining the poorly understood accretion process. While impossible to image directly,

Multiwavelength Observations of Accretion in Low-Mass X-ray Binary Systems

This work is intended to provide an introduction to multiwavelength observations of low-mass X-ray binaries and the techniques used to analyze and interpret their data. The focus will primarily be on

Phase-resolved spectroscopy of the low-mass X-ray binary V801 Ara

We present phase-resolved optical spectra of the low mass X-ray binary system V801 Ara. The spectra, obtained in 2014 with IMACS on the Magellan/Baade telescope at Las Campanas Observatory, cover the

High-Speed Optical Spectroscopy

The large surveys and sensitive instruments of modern astronomy are turning ever more examples of variable objects, many of which are extending the parameter space to testing theories of stellar

Structure of accretion flows in the nova-like cataclysmic variable RW Tri

We obtained photometric observations of the nova-like (NL) cataclysmic variable RW Tri and gathered all available AAVSO and other data from the literature. We determined the system parameters and

TLDR
The recent and future challenges in the burgeoning area of time domain astrophysics are reviewed, with particular attention to persistently variable sources, the recovery of reliable noise power spectra from sparsely sampled time series, higher order properties of accreting black holes, and time delays and correlations in multi-variate time series.

Analysis of spiral structure in the accretion disc of the nova-like cataclysmic variable EC21178–5417

We present an extensive Doppler tomography study of the eclipsing nova-like EC21178–5417, which exhibits the classic accretion disc signature in the form of double-peak emission lines in its

Multicolor Photometry of a Close Binary System with an X-ray Source

Four-color WBVR photoelectric observations of close binary system (CBS) HZ Her = Her X-1 in 1986–1994 are presented. Two-color diagrams (W–B)–(B–V) and (B–V)–(V–R) are given, which make it possible

Black holes in binary systems. Observational appearance

The outward transfer of angular momentum of accreting matter can lead to the formation of a disk around the black hole. The structure and radiation spectrum of the disk depends, in the main, on the

BLACK HOLES IN BINARY SYSTEMS

Since the observational detection of black holes is inherently difficult, it is important to begin with a clear idea of the general possibilities for such detection as they seem practical from
