The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.

An astronomical instrument is a device for observing, measuring, or recording astronomical data. [citation needed] They are used in the scientific field of astronomy, a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
The team devised a way to measure the surface gravity of distant stars to help determine if the planets in their orbit have life-supporting conditions.
Computational astrophysics refers to the methods and computing tools developed and used in astrophysics research. Like computational chemistry or computational physics , it is both a specific branch of theoretical astrophysics and an interdisciplinary field relying on computer science , mathematics , and wider physics .
Amy Mainzer (born January 2, 1974) is an American astronomer, specializing in astrophysical instrumentation and infrared astronomy.She was the deputy project scientist for the Wide-field Infrared Survey Explorer and is the principal investigator for its NEOWISE extension to study minor planets [1] and for the future Near Earth Object Surveyor space telescope mission.
Theoretical astronomers use a wide variety of tools which include analytical models (for example, polytropes to approximate the behaviors of a star) and computational numerical simulations. Each has some advantages. Analytical models of a process are generally better for giving insight into the heart of what is going on.
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
