Question: Which discipline of physics are also used in astrophysics/

Generally, either the term "astronomy" or "astrophysics" may be used to refer to this subject.
Based on strict dictionary definitions, "astronomy" refers to "the study of objects and matter outside the Earth's atmosphere and of their physical and chemical properties" and "astrophysics" refers to the branch of astronomy dealing with "the behavior, physical properties, and dynamic processes of celestial objects and phenomena".
In some cases, as in the introduction of the introductory textbook "The Physical Universe" by Frank Shu, "astronomy" may be used to describe the qualitative study of the subject, whereas "astrophysics" is used to describe the physics-oriented version of the subject.
However, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics.
Few fields, such as astrometry, are purely astronomy rather than also astrophysics.
Various departments in which scientists carry out research on this subject may use "astronomy" and "astrophysics," partly depending on whether the department is historically affiliated with a physics department, and many professional astronomers have physics rather than astronomy degrees.
One of the leading scientific journals in the field is the European journal named Astronomy and Astrophysics.
The leading American journals are The Astrophysical Journal and The Astronomical Journal. 
Solar physics is the branch of astrophysics that specializes in the study of the Sun.
It deals with detailed measurements that are possible only for our closest star.
It intersects with many disciplines of pure physics, astrophysics, and computer science, including fluid dynamics, plasma physics including magnetohydrodynamics, seismology, particle physics, atomic physics, nuclear physics, stellar evolution, space physics, spectroscopy, radiative transfer, applied optics, signal processing, computer vision, computational physics, stellar physics and solar astronomy.
Because the Sun is uniquely situated for close-range observing (other stars cannot be resolved with anything like the spatial or temporal resolution that the Sun can), there is a split between the related discipline of observational astrophysics (of distant stars) and observational solar physics.
The study of solar physics is also important as it is believed that changes in the solar atmosphere and solar activity can have a major impact on Earth's climate.
The Sun also provides a "physical laboratory" for the study of plasma physics.  
The field of interest for this journal, Astronomy, includes in its the scope sub-topics of astronomy.
These are stellar astronomy, celestial mechanics, radio astronomy, physics of the Sun, planetary astrophysics, astrophysics theory, and astrophysics science through observation.
Also included are methods of astronomy and instrumentation. 
The National Space Science Data Center serves as the permanent archive for NASA space science mission data.
"Space science" pertains to astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science.
As the permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and, in some cases, to the general public.
NSSDC also serves as NASA's permanent archive for space physics mission data.
It provides access to several geophysical models and to data from some non-NASA mission data.NSSDC supports active space physics and astrophysics researchers.
Web-based services allow the NSSDC to support the general public.
This support is in the form of information about spacecraft and access to digital versions of selected imagery.
NSSDC alsoprovides access to portions of their database contains information about data archived at NSSDC (and, in some cases, other facilities), the spacecraft which generate space science data and experiments which generate space science data.
NSSDC services also included are data management standards and technologies.NSSDC is part of the Solar System Exploration Data Services Office (SSEDSO) in the Solar System Exploration Division at NASA's Goddard Space Flight Center.
NSSDC is sponsored by the Heliophysics Division of NASA's Science Mission Directorate.
NSSDC acts in concert with various NASA discipline data systems in providing certain data and services.
